Something is not right, i need your expertise guys!

[BadGrandpa007]

Hi guys im new here, i hope this is the right place for my question…
I grow an autoflower, (RQS, Royal Cheese auto) its in the 2nd vegatative week i think… nearly 4weeks after sprouting from the soil…
It keeps growing, but this week it started to show little signs that somethings wrong, this is my 2nd grow, im an amateur
I cant figure out because there are too many simptoms, im not experienced yet so i want to ask you guys wtf is wrong with my plants!

MATERIAL:
soil

LED:
mars hydro SP250 250W LED (now im keeping it on 60-65%% and aprox from a 20" distance… i dont think its the light… maybe the light is too weak even. anyway…

NUTRIENTS:
T.A. (Terra Aquatica) TriPart nutrients, i started to use them la week ,starting from the 3week from sprouting, whe the first true leaves did grow (a leave with only 3branches), and i used only 30% from the does, rthen when i saw first levaes with 5branches i upped the 30% to 50%… it looks kinda anutrient burn, and this week i feed it only with balanced water nothing more, nothing less, because the soil has nutrients inside also…

PH:
i try to do steady 6.5 solution (GHE 1-5-0) Ph down

TEMPS:
min 17/18C at night over the day (19/5) to 24-26C, additional co2 is there because i live in the same rooms, small rooms, so co2 builds up very fast, but i dont think its related to co2…

RH:
trying to keep it 55-60%

first two pictures are from the last week, the others from yesterday… it keeps growing fast, but… there some signs… what could this be? i tend to think i started the nutrient program too soon, because soil already has a lot nutrients from my garden… but from the other hand it looks like a deficiency to me, i dont know guys, im an amateur, this is the second grow in my life… i cant do any expertise, im confused…the leaves ar colored and some places the tips are like from nutrient burn…

btw the leaves are pointing down i think just because i took the photos when the day cycle tarted (i turned on the LEDs minutes before that), but thats only my opinion…

sorry for my bad england

It looks to me like your plant needs water.

[Spiney_norman]

Agreed.
Did you transplant it recently?
And that meter you have in the pot is nearly useless.
They are hugely inaccurate and I recommend you don’t trust it.

[BadGrandpa007]

the first to weeks i barely watered it because it was so small, a seedling you know? like 25-40ml in the first week from sprouting, 2nd week 50-75ml, 3d week aprox 100ml in that 3gallon pot, and now when its bigger i do aprox 300ml… trying to do 1day in between and then 2days, 1day in between and then 2days in between… i cant imagine how big the roots are, maybe many parts of the roots dont get enough water, i dont know, i dont have much experience… i dont know if i did good with the aditiona lholes n the pot, but i thought, it will be difficult to verwater it…

[Spiney_norman]

Over watering is not too much water at once, but too many waterings in a given period.
You should water that soil completely until you get run off out the bottom and then wait for it to get dry and lighter when you lift it. Not bone dry of course, but mostly dry. Your plant is probably really thirsting for water. Otherwise it looks great.

[Bonjoyle]

Want to help too but a bit confused. You have alot of big nice holes in the pot but the other pics show a liner. Does the liner have holes too? At this age you should be watering to run off (flood) then wait as others have said until the pots are light again and then repeat. Run off is the reason I asked about the liner.

[Spiney_norman]

@Bonjoyle

the other pics show a liner

I think he has a grow bag in the plastic pot. At least I took it that way.

[Audiofreak]

Soil looks real parched.

[Skydiver]

@Bonjoyle

Does the liner have holes too?

Looks like some sort of a cloth liner inserted in the pot.

I also see some indication of a magnesium deficiency starting on some leaves.

I agree
on your next water use enough water so that the soil becomes completely saturated but do this over an hour or so because if done all at once you will have a lot of water seep out as the soil looks very dry. It may take 4 liters or so just apply slowly at first with 250ml and once that settles into soil add some more. Continue until you start to get water coming out the bottom into your saucer. Let that wick/soak back up and after 30 minutes if it hasn’t all wicked back up into soil then dump the saucer.

Before watering it lift the pot to get a feel for its weight when pretty dry and after watering do the same.

Leaving the meter in the soil will ruin the meter. It’s not designed to stay in the soil.

Hope this help

Give that girl a good watering and those wilted leafs will stand up.
Happy growing

Always try to upload a clear picture in white light of any issues you may have to allow the community to assist you.

I am particularly interested in knowing more about the soil you are using. Like you stated, it’s likely way early to be adding nutes. That said; plant looks pretty good other than some ‘guarding’. Plants will also droop ahead of lights out and after lights on.

BTW if using that soil meter I’d pitch that in the garbage and get a decent set of digital PH and TDS meters. Those probe type meters aren’t worth the $10 they cost. Expect to pay anywhere from $80 to $200, depending on the brand. Apera and Bluelab are both good choices and don’t forget to purchase calibration solution and storage solution.

Really can’t stress that enough.

[BadGrandpa007]

2days ago i watered with 1L each, 3x times more than before and this is how they look now… The leave tips are burnt from the LED i think (1plant), but its strange, i dont know why other 2plant are not burnt the same way, the LED height is the same distanec from all plants. didnt check the height for few days and upped up the LED some 15% and the LED was too close i think…
These meters ar garbage, i dont know why i put them there
im thinking about my pots, that have these big holes around, the i made them so i cant overwater and so that the roots have more oxygen, but it means also the soil is drying out much much quicker this way…

[BadGrandpa007]

yeah i know, i should buy a ppm/EC meter, i have a PH meter, but it doesnt show TDS, also i shoud buy a lux meter to calculate the aproximate PAR or DLI…

[BadGrandpa007]

I have only a PH meter, trying to do 6.5 every time…

Many of your questions i answered in the first post, please take a look there…
-Age - now it already the 5week starting from sprouting
-Organic soil, from my garden, but the first 3 weeks i didnt water it enough, it was completely dry, i dont know if microorganisms are still alive now, probably not anymore…But this week one more time i will water it with 1L of balanced water and then i will start to contuinue to add some nutrients (mentioned the brand in first post and the dosage)
-4Gallon pots with big holes around everywhere so the roots have more oxygen and i cant overwater it, but now im thinking, this way the soil dries out much much faster…
-PH 6.5, dont have any ppm meter… TDS measured ppm right? i measure the PH after putting nutrients in the water and PH down… thats it…
-grow size 2.4 - 3plants
-LED - first post 250W LED 231W, estill keeping at 55cm distance, was 50, at 60-70%
-schedule 19/5
-Temps and RH mentioned in first post
-Ventilation is nice, RH now 55 all the clck aroung, the 5weke starts now.-plenty of co2 because im living in the space, if i ventialte my rooms over night its already more tha 1200ppm co2…

hope this helps!

now they look prety good, and on the new upper leaves i dont see any spots anymore, the stems are soo big now after i watered it with 1L each to full runoff, before i gae them 300ml each? i thought its enough… but yeah, it wasnt., so if a plant does get enough water and its already big it also cant take up nutrients from the soil, so deficiencies can show up only because not enough watering right?

[Skydiver]

Water helps keep the critters in the soil alive and doing what they do which is eat reproduce and poop and get eaten by bigger critters. What they process becomes available to the plant.

They look pretty good to me.
If you see them drying out quicker with the pot set up your using by all means water more frequently.

As far as using soil meters I’ve been using them since I started growing and they do work if you know how to take care of them.
They may not be as fast to establish a reading nor to the .01 of precision of the digital ones but they do work.
If you buy a $10 meter whether a liquid meter or a soil meter that is what you get. Will they work? Yes. Will they work reliably? Yes if used correctly and taken care of.
If you spend $50 on a liquid or soil PH meter will they work better and last longer? Yes as long as they are used properly and taken care of.

Many don’t use soil meters as they have a different grow style that dictates always checking LIQUID PH and PPM going in and going out with run off and all that goes with that style.
Sometimes things are repeated over and over and that becomes truth and that’s ok but I use them and have for years and for me they do work. Do they fail? Of course they do. Do they need replaced? Yep
I have that exact meter and have had it for 5 years and just the other day broke it out helping a friend who just started growing and had it in the soil comparing it to my other $50 meter and my other $60 new digital soil meter that was just calibrated and they were all within .02 of each other. Is that difference ok? It is for me growing in living soil. Is that ok for other grow styles? Maybe not but I do know they do work if used properly and taken care of properly.
