It is close to watering time so I thought I’d ask about this. The one with tips curling down is a Chocolope and the yellow tips are a Gold Leaf.
Last water was just RO water with CalMag and was 2 days ago and runoff was 6.2/1100 for Chocolope (tip curl) and 6.3/1500 for Gold Leaf (yellow tips). That water had a pH of 6.9 going in because I knew the soil pH was low (runoff was 5.8 when I gave it full Fox Farm trio nutes @ 6.7pH 6 days ago). However the plants looked pretty good then. This didn’t happen until the plain watering.
Other things of note: I switched to 12/12 just over a week ago. I defoliated the Chocolope 2 days ago. Gold Leaf is untrained/untouched. Soil is mostly FFOF with some perlite, castings and dolomite. Topped off with Roots Organic original. Temp and humidity have been a little high at times, up to 80*-82* and 55%-65% sometimes.
Just looks like it’s the tips. Humidity looks to be the most likely cause.
Was it close to lights out? Leaves might just getting ready to sleep.
Either way, the leaves look great. The curl i wouldn’t be too worried about. @Hungrybud
The tips are nute burn, and you have some signs of nitrogen claw as well. Nothing major in my opinion, probably just a little more charge left on soil than you were expecting.
Your runoff is high, so probably just a bit of very, very minor nute burn & high nitrogen, plus your vpd is just slightly off (temps too high for your humidity level, but not by much). Also, do you have a fan blowing directly on them?
Thanks all. Slight Nitrogen excess was my guess too. I forgot to mention that I used Xtreme Tea along with nutes a week ago and it was not ‘brewed’ but rather ‘quick mixed’ and also had Azos added. Perhaps it was a delayed reaction and the tea made too many nutes available a few days later?
My next watering was supposed to be with nutes (only Tiger Bloom and Big Bloom tho, no Grow Big) so maybe I’ll just use Big Bloom. I was going to make tea again too but maybe I should wait.
Tent is mid-high 70s temp and low-mid 50s rh right now. It is unseasonably warm and humid outdoors right now. I sort of rely on a cool/dry outer room to keep the bloom tent cooler and drier by running exhaust fan.
@blackthumbbetty
Yes, I do have a fan on them. There is one oscillating and one fixed that I just added today to try to help move more air. There was very minor PM on very bottom leaves which is what prompted the defoliation and added fan. But this curling was already underway when I added the second fan.
Good morning, The one with the yellowing tips I would have to say has NUTRIENT BURN and the other very well may have the same thing. What was your feeding schedule you never said and how much and how offen ?
This information is very important so please be honest ok…and we’ll get your plants back on track.
I use Fox Farm trio and pretty much follow the chart. Last feeding was the first time I used 2 tsp/gal of both Grow Big and Tiger Bloom but I did not use Big Bloom because I made the Xtreme Tea (compost tea) with 2 TBS/gal Azos added.
I feed every other watering and always (nutes or not) use RO plus CalMag, then pH adjusted. When giving plain water, the last 25% has Big Bloom in it (3 tsp/gal).
@garrigan62 will weigh in but having had this same issue a year ago, he got me on track and I’ve been following his advice.
Your FF nutes are at a level IMO that is too high to support good growth in some plant strains. If you use a TDS meter you will likely find you have a very high amount of solids in your nutrient solution. Like 1,800 plus PPM and some plants don’t like that. I run all of my vegging plants at between 800 and 1,000 PPM and that’s TOTAL TDS so include the starting value of your water. In my case it’s around 325 PPM and I add around 600 PPM of nutrients to that volume to give me around 900 PPM, give or take.
If you are in soil you have little need for any vegging nutes, assuming good soil construction. I’ve never run any veg nutes in soil; just media.
Ok, I see your 3rd pic with the curled tips It’s still called " NUTRIEN BURN "
Here is another pic I have showing the very same as your and it’s from Nutrient Burn
All this below =Nutrient Burn
Soil is mostly FFOF which is very hot soil to begin with, with some perlite, castings and dolomite. Topped off with Roots Organic original. with CalMag
Tiger Bloom and Big Bloom Xtreme Tea along with nutes a week ago and it was not ‘brewed’ but rather ‘quick mixed’ and also had Azos added,
And one other thing it’s not " NITROGEN " IT’S " NUTRIENT BURN "
As everyone has already noted, you’ve got some slight nute burn. Not a big problem, but your PPM is a little high, so I would recommend a little flush to bring it back down.
Thanks again everybody. I’ll give it just water today and measure.
I have given all 4 plants the exact same water/nutes/soil and the Gorilla Glue (not shown) runoff was 855 while the Gold Leaf was 1500 and both Chocolopes were 1100. All had pH between 6.1 and 6.3 but that was with 6.9pH going in. I’m guessing they will be fine with slightly lower pH water by now.
K, so I watered with RO plus CalMag plus 2tsp/gal Big Bloom (that’s the organic matter one with castings/guano and at about 66% strength). About 330 ppm and 6.6pH going in. 1 gallon per plant (spaced out over 30 minutes or so) into 5gal pots and got ~10%-15% runoff.
All had similar TDS at about 1050ppm +/- 20ppm. 3 of 4 had similar pH ranging from 6.1 to 6.35. However one of them was 5.55. Interestingly, that one is a Chocolope but does NOT have curl/claw. The one that does have curl/claw seems to be growing a tiny bit faster and budding a little better but maybe not a fair comparison because one was topped once and the other was fim’d once. Curly was the topped one.
My guess is to stay the course and adjust each plant at next watering, again with no nutes.
Is it OK to make compost tea next time? That stuff has fairly high pH and I don’t adjust it but I do adjust the rest of the water to water it all in. The tea is only maybe 20% of total water added.
Obligatory Sunday night pic, they are all a bit droopy except the Gold Leaf (top left). Others are Gorilla Glue (bottom left) and Chocolopes on right. Curly in the back.
I got tell ya I think your right staying the course. They do look better but only you know for sure and I think you should go with your gut feelings. keep us posted and we’ll see how they do in the next few days.
I would back off the tea for now , at least until you get this under control. The go for it and see what happends
I wouldn’t add anything to the water just yet. Try and get the Ph under control first before adding tea. Adding any kind of nutrient now could make matters worse rather than better.
@raustin
Does that include Big Bloom, or even CalMag? I use RO water, my tap water has chloramines and is only 40ppm TDS anyway. So I always use CalMag and almost always use Big Bloom but often both are less than full strength.
