Slow seedling, bit of problems and general worries

hi y’all! imma start by providing some baseline info as that should make for a good start

-What strain, Seed bank, or bag seed: extreme impact auto from heavyweight seeds
-Age of plant: 8 days for 2 of em, day 6 for the third fella
-Method: soil with 1/4th of total volume in vermiculite as the local shop was out of perlite and they sold me this one instead and i just bought it without thinking over it because i’m dumb.
-Vessels: 3 3gal fabric pots
-PH and TDS of Water, Solution, runoff: ph out of the faucet is 8.4 at 1c (33f)
-Method used to measure PH and TDS: ph pen, ppm/tds/ec pen is in the cart atm
-Indoor or Outdoor if indoor, size of grow space
-Light system List brand and wattage/spectrum: noname cheapo led brand “full spectrum”, currently at 18DLI, then will move over to a 300w hps for the flowering and to put another source of heat in the tent (if we’ll get that far to begin with)
-Actual wattage draw of lights: don’t got the tools for that
-Current Light Schedule: 20/4
-Temps: peak is 6c during the day (43f) nighttime is -4c (24f), in-tent it’s 25.5c/26.3c (77/79f)
-Humidity; Day, Night, local fluctuates from 70% to 96% on the outside, hygrometer is in the cart atm
-Ventilation system; 6" inline fan, yet to be hooked up carbon filter and in tent fan for moving the leaves
-AC, Humidifier, De-humidifier: currently using my bathroom heater and seedling mats for “Ac”
-Co2: lmao no

so, current problems/worries are related both to speed of the growth due to minimal progress compared to what i was able to see on other grow diaries and the fact that a the first set of leaves from the seedling have the tips of each frill curled slightly up and no matter what i seem to do there doesn’t seem to be an improvement, thus I’ll just post pictures of the different days and ask if this progress seems normal to you or not and in case whatever it is that is wrong about it that i failed to notice

9th of jan

11th of jan

12th of jan

13th of jan

14th of jan

and then another pic set 6 hours of light after on the 15th at 1am

i am aware that there have been some slow downs from me not removing the seedling cap and the underlying membrane during the first 2 days thinking that they would manage to do that by themselves, which i assume is what has caused the stretching and delays in the growth, but at the same time it has been 8~ full days since they’ve gotten out of the ground and they seems to be stuck at this phase still, reading around it seems like next time even with autos it’s better if i let them germinate in a smaller piece of substrate so as to limit the early root stretching
before the seedling goes into veg, so fellas, got any takes?

What’s your watering routine, that medium looks super dry. You’ll want ideal environmental conditions, lighting and nutrients on point when growing autos. They need a great start or you’ll be looking at a very small plant when flowering sets in :love_you_gesture:

Yes watering and looks like it is stretching. Can you measure light lux or unimole/m2 but low light will make slow growth as will watering…

current watering schedule was basically nothing if not the smallest amount of water (60mls~) in a spiral pattern as that seemed to be a good technique for seedlings being put in big pots as that was helpful for the roots and they’d just take the water from the air, there’s a significant chance i extended that for too long given the soil being bone dry at 6cms(2.3 inches) of depth, did a first light watering to make the top non water resistant and then gave n.1 and n.2 400mls of dechlorinated ph balanced water and n.3 200mls as she’s starting to show stem growth too (to identify the different plants if you look at the names of the files you have the first 2 numbers which indicate the day and then a second number which indicates which plant is in the picture, then for the 2nd or 3rd picture of the same plant there’s an extra letter, didn’t keep track on the 11th of jan so i just wrote some nonsense), took some pics but as they were taken in the 15th too and there was barely any difference if not n.3 having spread her first leaves a tiny bit more and the node starting to move i don’t think i will upload them, will look in 10ish hours if there will be some significant change and then report when i can sit down in front of my PC

"They need a great start or you’ll be looking at a very small plant when flowering sets in :love_you_gesture: "
yup that’s why I’m eating my nails atm

checked for the lux and did all of the calculations before starting with the seedlings, n.1 and n.2 are getting 19dli if not more as they got over the distance where i measured it, n.3 while being in the same lighting conditions doesn’t seem to be stretching at all and seems to be almost caught up with n.2 and n.3 with the node development (which is not a lot but n.3 is starting to become comparable), i assume n.1 and n.2 stretched at the beginning as they didn’t manage to get the seedling mesh off early, will try to center them better under the light and raise the dli to 25 tomorrow if just the water doesn’t bring changes.

(read the comment up above, currently gave them a watering that while not being excessive should be enough to tell us if the problem was not giving enough water for proper grow)

What size is the vessel and the medium you’re using? The temps need to be around 76-85 and the RH north of 65% for this growth stage. Most growers dome seedlings to keep the RH high. They’ll absorb the moisture through their leaves while they’re putting down their first roots. I water about 2 shot glasses every 3 days removing the dome for misting and some fresh air periodically through the day :love_you_gesture:

the vessel is a 3gal fabric pot and the temps are being kept between 77 and 79f, relative humidity in this city ranges between 70 to 90% between the day and night, did the humidity dome thing at the beginning while waiting for the seedling to sprout, after they’ve sprouted and 3 days had passed i took it off, usually i aired the domes at 12h intervals due to work (I’m a chef so i spend a lot of time in the kitchen), as to the rh in the tent I’m unsure, still have to get my hands on a hygrometer, will buy some tomorrow probably, considering the increase in temp it could be raised some more, adding some cups filled with water and cloth to increase humidity

My initial impression is they’re thirsty :love_you_gesture:

thanks and noted on that xD, just gotten back from checking and adding something to potentially increase humidity and yup, they were thirsty alright, in less than a couple of hours they have already gotten a bit bigger, now, I’m unsure if this is because of some bias or what, I’ll let the pictures have the final say over this tomorrow once I’ll take them, if the problem was underwatering I’ll have a hearty laugh about this and see if to proceed with LST or not (once there’ll be some nodes), what’s your take given the current stunting? would you predict a higher yield from one main cola (if there’ll be one) or an LSTed auto that was stunted at the beginning? what would you evaluate to make this decision?

little update, boy were they thirsty, the soil was completely dry in less than 18 hours post watering, gave them 600 MLS each this time and will check as soon as i get back from lunch rush tomorrow, the plants have shown minimal growing but at least they’ve started and there was a period where they were doing the “praying” thing, moved the light delivery up to to 25 dli, noticed that there are also black flies jumping around which i assume are fungus gnats, i will go get something to kill them asap, currently surprised by plant n.3 which is starting to grow her 2nd set of leaves already, any guesses as to what is the brown spot on plant n.2? is that a sign that the cotyledons are starting to run out?

here are some pics for the day

today is officially day 10 for n.1 and n.2, they are looking more lively but still underdeveloped, time to see if with these changes they’ll take off or not

update to the update, put some cups with beer in one and wine in the other to attract them, looked and each one of them had the leaves praying nicely

It’s not light, they aren’t stretching like that but your soil is mad dry you probably didn’t soak the soil before planting I’m assuming but just up your watering and see

welp, i am officially clueless over anything and everything, 25dli didn’t seem to do much or to encourage much growth, n1 and n2 have m i n i m a l growth and the same goes for n.3 just to a lesser extent, no signs of light stress as far as i can see, increased the light to 31DLI and turned on the fans, if it’s not the humidity, and it’s not the light, and it’s not the temp, and it’s not the watering what is left are the nutes, if the soil is dry tomorrow i will add some bio grow at half strength, the ppm pen will come in tomorrow too

pictures for the day

do you have any potentially useful approach to recommend?

upped the watering significantly, now they’re getting 800ml each

I’m a risky grower so my advice isn’t wise😂 but I’ve recently saved 3 autos after overwatering as well and i transplanted them into some fresh soil with no nutes and added some extra perlite but dont soak the soil soak around the soil then plant the seedlings in the new soil if your roots aren’t rotted you should see little white fuzzy roots and take out the seedling from the current soil just overly soak the soil cut the container open and take it out in whole, start picking the soil from the bottom to the top till there is little to no soil then plant them into the new soil which some micros sprinkled in the hole your planting in the new soil. Then fill the hole with soil it doesn’t have to sit up perfectly straight or anything it with grow towards the light anyway, but water it just enough to soak a small circle in the middle kinda like your starting from the beginning with maybe 20 ml every 3/4 days and it will grow out of it because it could be rot rot too but as long as you see the white fuzzy on at least a good chuck of your stems when you take it out you can save it


These were the ones i saved from root rot

I can also help through the transplant process

You are in a big.pot. Very dry. Lots of debris. Bark etc.
If it was me i would water till the pot is a little moist. Not on the seedling. All around the edges. Get some moisture into the pot for the seedling to chase. The debris in the soil inhibits root stretch a little. That will break down. The sprouts look healthy. We ALWAYS warn against damping off but can go both ways. Dont go crazy but those girls want water. They are ready to take off. Just my thoughts.

Should not need nutrients yet. Just ph water.

read the whole message and you currently have me looking at the monitor like O.O, damn you weren’t joking over being risky xD, due to me not having any backup pot and our shops being closed for today and tomorrow i think i will do a watering with oxygenated water around the base of the plant (so just where the roots are to avoid killing all of the good bacteria and useful mycelium so that the ones needed to break down the biobizz fert will survive) to ensure that it’s not root rot stunting growth, i would be quite surprised if it even was root rot to begin with considering how dehydrated the soil was 2 days ago, but thanks for the answer nonetheless, i will keep this in mind

the debris in the pot is on the top layer only as far as I’ve been able to see, below it’s a single layer of soil and vermiculite, i have a bad back so i avoided mixing “traditionally” to prevent flare ups, just tossed the pot left and right like a bowl letting things mix by themselves and I’ve seen all of the branches and huge chunks get on the top layer, from doing that for 10 minutes for each pot i’d consider it safe to assume that there aren’t other pieces under the soil, do you think differently?

damping off was the thing i paid the most attention to avoiding during the early stages due to how much I’ve read about it online, will see how it’s going to respond in a couple of hours and take notes, also when writing “never on the seedling” do you mean on the leaves/stem or at a certain distance from the seedling in by itself?

i do hope so too xD

will change the watering technique for tomorrow and report
