It looks like your leaves are canoeing and this can be caused by to much N

johnny-0

It could be to much N.Leaves curl up (canoeing)or possibly it got to cold for awhile or lol it could be to low humidity--IM very confused!

JMagick

hey Johnny yeh the humidity is around 40% right now i just did a nute change today so hopefully it will clear up the problem i am running EC 1.0 now as i got my bluelab ec truncheon today hopefully it will help me fine tune the amounts of nute they get! and that might sort it out

im no pro but it doesnt look like a sigle element deficiency to me...im gonna say your PH is way too high.

the ph is most likely your issue since you say you have no way to measure it...tap water is usually around nuetral (7.0) or higher and your ph should be around 5.6-5.9 with 5 and 6 being acceptable extremes.

ph is especially important in hydro setups as there is no soil to properly buffer a ph thats either too high or too low. it doesnt look like nutrient burn to me, but at this stage without a ppm meter it is a possibility...

just my .02

good luck
