Bad leaf curl...

[Sativa_Grows]

Oh boy, this is a fan leaf from one of my Deep Chunks...I just cought this, the plants are so bushy that I couldnt see the bottom fans anymore...

They're in 1 gal pots with straight FFOF, been watering with R/O water. The leaves affected are dry and fall off the plant easily, some have brown spots...PH issue? Defficiency? Hight temps and low humidity wouldn't have anything do with it would it?

High temps Low humidity is your answer.

That type of leaf curl is from low-humidity.

I am guessing your humidity is >30? 20?



Edit: I just read the part about the bad-leaf being under-neath. I still am sticking with my low-humidity answer, BUT, it could just be dieing off as its not needed.

RH is <25, wont even register on my meter, figured they could deal with it being a pure 'ghani and all. I'll raise my lights in an attempt to strech out my plants for better airflow and to cool the tent down. If I can find my humidifier I'll put that in there too and report back in a couple days. Thanks for the quick reply!

Hey man. How many of the other leaves are doing this? If its a leaf thats "at the bottom" of the plant, its not new-growth and u shouldn't worry about it.

I had super low humidity problems (wouldn't even register). I slowed down my air-flow and as the plants got bigger it wasnt a problem. you'll be thankful for that humidity in flower, as you want it to be lower. (30 range)

Make sure there is no fan directly blowing on your plants
