Dont Know?

One of my Plants, Ethos Citral Glue looks healthy as can be, loving life... Other plant, Wedding Cake x Inzane in Membrane is being a little B... Few days ago leaf edges slowly started turning up which looks more and more like tacoing from the stem outwards. No signs of Clawing, no burnt tips, no other curling. Now this morning almost literally overnight lower new growth looking like this... Rough/bumpy, lighter veins and interior flesh, worse tacoing. Plant still growing ok, is not stunted. Should have plenty of Magnesium/Calcium. Gets fairly hard Tap water so I would imagine decent micro nutrients. Temps stay about 81F with RH ~60%. Plants recently top dressed with Dr Earth 4-6-3 and a little bit of Dr Earth 5-5-2 and worm casting Tea. Get occasional Recharge and watering with Epsom Salt. If anything they should have borderline too much Nitrogen, plenty of Phos and Potas, plenty of Mg, have not supplimented Calcium but Dr Earth, Worm Castings and my tap water should have plenty. Good living soil with nice fungys and microbes from Mycorrhizae and Recharge so I would think its not a lock out? Someone help me figure this out please.

Im thinking maybe they are getting too much wind? Doesnt explain the "bumpy" rough texture on other leaves though. And that my other plant is perfectly fine...

Heat stress and no air moving across it. Your thermometer is showing 77 in the hole. Fill your containers to the top. Backfill as it compacts.

What's your medium?

well theres more than enough air movement, i actually turned my fan away for less direct airflow. Temps get as low as 72 at night and max about 81 during day. Unless it was getting too much wind, which is certainly a possibility, I would likely rule out heat or airflow. And humidity. My VPD is fairly good.

Medium is 50% Fox Farm OF, 20% perlite, 30% Worm castings maybe 5% Vermiculite thrown in for Silica. Stays fairly wet for longer than i would like but plants havent been watered now in 3 days and im pretty careful about watering. Im def going to switch to mostly coco after this run i think.

Some young plants want higher Rh. When my gg4 was small it looked rough till I raised rh% to 70+

sometimes it hits 70%, usually it around 60 tho tbh... I dunno there just no other signs to go off than some canoeing from the petiole and "irregular" look of some leaves. Im thinking maybe potassium deficiency would cause frilled up serrations but only way would have K Def is lockout from too much K, and theres no burnt tips or yellowing. I started to think maybe I have Russett or Broad Mites (god help me) but theres no signs of rough spots of being eaten... Maybe they have gotten too much Calcium?

I say they... its just the one problem child. Other plant green and healthy as can be. Vigorous and loves life. Rough looking leaves and slightly turned up edges been going on with this plant for at least a week now. No other signs of anything else other than this morning when lights came on I find tacoing at petioles.

Agree that RH being that low doesn't help for veg, but for FFOF, shouldn't have put any feed yet. That plant is still a baby. I'm on 2nd week of flower and just now added a top dressing of flower girl at 1/4 cup for a 5 gal container. Won't add anything else for another 3-4 weeks.

yea and it def has some signs of too much Nitrogen. But not a single sign of tip burn or other marks. Or clawing/curling. Maybe its just being overly sensitive about Nitrogen? The other plant is a normal healthy green, but this obviously is a bit too dark.

Whats your average rh? I thought I had something going on myself and never would have thought rh% makes so much difference. Try keeping it 70%+ for a couple days

This is it currently. It fluctuates from 60 - 70%. Temp is usually a few degrees higher, more often about 81 or 81F. I dont think i can get it any higher tbh...

Any reason you didn't actually fill the pots?

They look at most two weeks old. You started them in FFOF and you've already added top dressings? Why? Mostly likely your issue right there.

Pots have little less than 4 Gals each, i didnt really see the need to fill them to the top, and i have room for top dressing later. They 5 gallon buckets.

They pretty much me just starting some plants to veg in my closet until i buy a new tent next month. Hung 2x QB96s, currently set to 150w each at around 36 inches.
