just decided to drop hours!

after posting my post about an hour ago, sitting here thinking whilst reading some posts, and decided to put her into bloom, i just want her to have a chance to grow a decent crop, the reason im doing this is because she has started to get some curling/browning on the tips and some lighter green on the outer edge of her leaves,
also the bottom leaves look grim not all of them are ill but some, they look lush green apart from that so im changing her hours/light so that i can assess her chances when she`s getting on a bit wiv the bloom stage! well wish me luck i need it!!!! hope she can manage it ill keep u posted she is beggining of 8th week 250 watt 2x2m tent with 2 small fan`s and one fan to suck out.

I started my plants flowering cycle at about 8 weeks also... there doing really good so far so good luck with yours.

i have dropped the hours now for the 2nd day now, dont think it would matter to much it is about 4 days earlier then i was going to do. It`s just the leaves seem to be brwning, and the nutes im using are just the same as before no changes, so i think the reason for the tips curling and edges of leaves starting to crisp, the humidity is about 35-38 and 39-40 when off, do u think this could be causing the problem? i have a 250watt hps for my flowering but i have been vegging with a metal halide, my tent is 1x1x2, i have 3 fans, one extracted at the top, 1 on an intake at the bottom and a smaller one inside mixing and circulating air around the tent, the temp is around 77 goes no higher then 79 when lights on and when lights off 66 but occasionaly drops to around 63, could this contribute to the problems that my girl is experiencing,thats y i have put her into flower .
