anyone????????????

could be alot of things.. do you check your ph

having the wrong ph can really fuck your ladies up, can we say NUTE LOCKOUT

ya i ph my water to 6.8 for soil

the 2 tone is strange ive never seen that in any of the info ive read or seen on RIU

though i do suspect nute lock out in some of the other plants

i have yet to do a runoff ph since i transplanted into the 3 gal pots

either way i was planning on flushing all my pots this weekend

you can always flush them

hey anytime I have seen any type of leaf curl it has been a ph problem, which if you have can cause the plant not to take up nutrients.

thanks guys you guys were right it was PH. i did a flush and run offs were in high 4 and low 5s ph!!!!! got them up to 6ph i kno i need to get them a little higher but i didnt want to drown them
