Plants are three weeks into 12off 12on. Look healthy. But the tops
of some of the leaves are curling down from the vein, not tips.
ppm's are 1320-1280 using GH nutrients. ph is 5.9 to 6.1.
any idea whats going on?

Filling-out the troubleshooting form is the only way your plant's situation can be diagnosedgoing to get an accurate response...but with the 'canoeing' of the leaves...my initial thought is a ph issue. But it's not affecting the entire plant. If only on upper leaves, it's perhaps heat stress and overwatering combined.
Anyway...fill-out the troubleshooting form, and someone with hydro experience should be in shortly to help. :thumbsup:
thanks rusty,
i let my friend load these pics and told him to fill out the troubleshooting form but he didnt do it. i dont think its hot in the room and i think the ones that are doing it are on the outside edges, not under the light. as far as over watering, he did increase watering from once to twice a day while the weather was nice. the medium is Roots Organic coco 0-0-0 in 12in mesh bottom pots on E&F. it drains very fast. i told him to get on the Q&A thing but we'll see.
thanks-

I did a flush after my first posting and some of the "canoeing" looks
better. Still have a few that are showing this curl.
Looks like light intensity to me, nothing to worry about, it is just not as bothered growing leaves as buds any more at this stage IMO.
Subzero. :thumbsup:
thanks sub,
a hand water flush to the few plants that were doing this has seemed to fix it. also watering was cut back from 2x to once a day. they are now getting a purple tint to the fan leaves. he posted pics under my name in another thread called "is this normal" ive had this before on purple strains and bubba kush (which gets purple in some spots at the end). i normally dont see it until the last couple weeks and it seems to get darker in colder weather. its never affected my yields. i think its just the purple nature of the plant. anyone?
