some help if you can!
ive got a leave curling problem on my plant..
diary here.. https://www.thctalk.com/cannabis-foru...ad.php?t=12006
the leaves are curling on this plant..
..its sister here is in good health, but also a slight leaf curl..
they are under a 400w hps 2ft above.. its not heat stress as there are 2 plants much closer to the light and they are fine.
im feeding them GHE nutes.. they were on 2.5ml /10l of gro bloom and micro for the last 2 weeks. the leaf curling started a few days ago. yesterday, as they were getting bigger and slightly pale, i upped the nutes to 7ml /10l gro loom and micro (as per guidelines provided on the bottle) and they have both got thier lush green colour back. ph is just under 6.0, it need adjusting everyday, usually rising to 7.. .everyday, i adjust ph back below 6.0.. ec is around 0.8.
its the leaf curl that bothering me..
ive heard its possible mg def? it cant be heat stress.. the room is 30degrees with good circulation.. notice also the lower leaves are burned at the tips..
help!..
thanks
