the claw

3 out 12 pants showing the claw. All plants seem healthy otherwise. Ph is in check. Using happy frog 7-5-3 , all under t5's 18/6, intermitant flow of co2 18/6, only water when they show signs of thirst. I have leeched, transplanted, sprayed foilage with Revive. The Ladies are 12 weeks old and show no other abnormalities othere than the claw. The claw is present on the upper third fan leaves with a few smaller curled leaves closer to the bottom( just a few). I have searched high and low for credible info and here is the advice I have read: too much water, not enough water, ph wrong, nitrogen toxicity , too much co2 , ventilation, lights. I am at wits end. I can live with the claw if I have to but can the ladies live with the claw and how does this effect the " bud". Gracious for any help available

the claw is usually a sign of too much nitrogen...

dude, i had the exact same problem with one of my 12 plants...it grew quicker and taller than all the others, but the fan leaves wept like their parents had just died from sprout even till now, week 4 of flower...as it turns out, this 1 was a hermie, sooo im thinkin maybe just a weak plants with bad genetics? i mean if all your other plants are doin great, then it could be just that...it my first grow tho so i dunno, i always thought it was a humidity or heat problem...good luck!

as mentioned, prob nitrogen toxicity. also just too much nutes sometimes for certain strains. it won't really hurt the plant, but the leaves will stat that way so you gotta live with it.

one of my plants that showed sex today "clawed" up on me a few weeks ago....i figured it was either over nuted with VEGnutes or i had overwatered whatever it was i fixed it and no more claws...but they do stay that way like silky said
