leaves,up down,up down

opinion needed please. what i have is 1 month old plant 15" tall, 11 nodes,10" pot.under 400mh at 18/6, ff soil and nutes.showed female preflower yesterday(yahoo). she's been very healthy BUTT, the past 5 days she starts drooping during the last 3 hours of the light cycle, butt she's back to looking healthy again after the lights come back on. ph is 6.5 in and 6.5 out. she does have some light purple on top 2 branches.fed twice 1/2 dose and once full dose.soil is dry 3" finger deep and meter, before watering, flushed her yesterday.read a few threads on drooping leaves, just not sure on this problem. i'm thinking it't a feed problem, butt not too big a problem because she doe's look great during the day. oh hummmmm,please your opinions are valuabe, thanks a lot.

p.s. sorry about the long post, no pics(daughter,desert,sand,lens) camera no worky no more,so wanted to give as much info as possible.
thanks again.

alot of what i read says to water when the top 2" of soil is dry. maybe you could try watering them a little sooner. if there's no other problems (discoloration, spots) it could just need more water.

good luck.

nothing sounds bad here.. the purple can be due to possible cold weather? or possibly just the strain itself. My last plant had some purple of the stem part of the fan leaves with no bad effects.. the drooping sounds normal. let it grow she can take care of herself. its growing let her do her thing


I am no pro but Im just sharing my personal experience.
take it how you want. GL

thanks for the input, I'm gonna get her nutes schedule straightend out and that should take care of it.
later.
