Strange leaf formation in grow

[bloodshot247]

Hey guys,

two out of three of my girls are developing new growth with only single bladed leaves. They are about 30cm high and about to be re-poted from 2.5L pots into 20L pots. All the older growth is fully developed and looks fine, it's just the new stuff over the past few days. Humidity is around 60%, temp is 26 light on and 20 light off ( 1 x 600 MH) Nutes @ 18 (Canna coco). Cupboard is totally light proof. Any ideas fella's???

marijuana reaches its maximum blades per leaf (usually 7, 9 or 11) and then slowly works its way back down to mostly 3 and 5 bladed leaves....fucked if i know why it happens but i have never seen a single plant that has grown any differently except for the so called "celery" strains which grow single blades like crazy

wantdachronic, I have grown these a couple of times in the past and they have never done this before. When they flower the colas have three and single bladed leaves. It seems like they have turned without developing buds. The light cycle is solid 18/6. Got me stumped???

Maybe if they are root bound? Could this cause the problem?
