lowrider issues

my girl looks light green throughout the plant but some of the leafs look burnt at the very tip (not along the blades). it is about 5 weeks from seedd.

i have only fed it once with 1/2 solution grow and molasses. i was thinking N def, but does that burn the tips too?

on another note, i am about to flower 3 WW x lowrider. They are looking B E A utiful. not showing signs of sex after 5 weeks so so i guess they didnt get teh autoflower part of lowrider. They are all branching like crazy though. going to be interesting to see

Not sure what to tell you, but I'll def. keep up with this post cuz I will be starting some LR2 X AK47's real soon...

thanks man. i just changed the light cycle today and put a temporary veg chamber below the flower chamber for clones i took of everything. total in flower now, 3 blueberry, 3 g13 haze, 3 D-cup(ww x lr2), and 1 LR2. the plan is to have a continual harvest with 4 plants coming in and out every2 weeks. i think i am going to do a g13 mom and a blueberry mom

No doubt! One thing I can tell you, from all the reading I've been doing, I know that LR plants prefer very little, or no nutes at all. How close are the plants to the light? Could that be what's burning the tips?
