Taco leaves

[IslandGrown]

Hey guys!, so this isn't my first grow but I've never encountered a problem like this that i just have't been able to diagnose. My Big Bang Auto seems to be curling its leaves upwards and on the very tip it is slightly yellow. I don't believe it is heat stress as my auto super silver haze has been right next to it the whole time and it is only very very slightly curled up. I also don't think it is wind stress or nutrient burn. The only thing that was different between these two that i can think of was that big bang was in a smaller pot for a while before i transplanted her. I did raise my lights just to be safe (even though CFL's give off not that much heat) and i turned my fan so it only slightly hits them. I also laid off on the nutes. I'm growing using 8 CFL's with sufficient lumens on a 24/0 cycle and they are in coconut coir. I put some pics! If you have any ideas please lay em on me!

What's your RH%? from your pix that look's like how they react to long periods of low humidity in my experience.. it also appears you have some other issue brewing as well.. maybe someone else can chime in with a better idea then me as I battle high humidity half the time lol.. so hardly see that happen in my plants.

Hey Deo thanks for the suggestion and i had that same thought today so i made a kind of improvised humidity dome i put a pic below. Tell me if you think this will help or hurt more...thanks! I just ordered a new humidity meter (my other one broke) so i'm not sure what my levels are.

That should help.. make sure you take it off for a few minutes a couple times a day to give them fresh air and continue to mist them with plain water. Keep an eye on them and see how they react for a few days.. Ideally you want 60-80% RH during Veg. w/ good fresh air flow to prevent any mold issues.

I also see some odd yellowing in your pix.. might indicate a PH related problem or splashed nutrient solution causing a burn .. do you PH your nutrient/water before feeding? and what strength are you giving them? They look very young to be feeding anything above 1/4 strength every other water.. might want to back off feeding them and just give them Ph'd plain water for a week or 2 if you haven't already to get that back in check and see if that improves as well.

Good thing is your in early veg and can fix all these problems and give them time to recover before flower w/o it affecting the end product much.. Good luck!

Unfortunately my PH is 7.2 because i ran out of PH down so i have to wait a few days. Do you think that could be the problem? Also i definitely over nuted...put about 4 tablespoons per gallon of botanicare pro grow. So i'm just doing regular water but while i wait is there anything household i could put into my water to lower the PH? Also i started getting eagle claw on one of my top leaves....thats a sign of over nutes right? I put pics

over-nuting causes effects like incorrect pH. a flush would help at this stage.

very important to keep an eye on yr pH as even correct ratio nutes will acidify growing medium over time.

also put some air/ventilation holes in that 'humidifier'. say, 3 or 4 X 6mm.

cheers!

Thanks for the help guys!

Too much light dude. Leaves are curling cause they can transpire fast enough with their root system, they're only small. Back the light off, get your temp/humd meter and you'll be better able to work out where to have tyour light source.
