Grow questions

Hi ..growing 4 fem ww in wilma 4 from seeds. The light am using is 600w MH for veg and will be changing it for 600w HPS for flowering.

They've been in for 3 days now and I've got my ventilation running 24h, my nutes PH is going up everyday and am adjusting it with phdown to 5.5/5.6. the EC started at 1.2 and I've kept it at 1.3 for last two days.

The humiditiy is 39% and my temp is 27c today, but on first day it was 40-45 % humidity and temp was 25-29c.

I'm using a cooltube with RVK125 fan for heat extraction and 100TT fan for air intake. And am running a 12"fan on 3rd setting (hightst) to circulate the air in the tent.

Please is everything going ok?? its my first grow..and I'm not sure!!

sofar 3 days under MH 600w light!:rasta:

Thats alot of light for a baby. you could run a couple of CFL's (75w or 100w) over it till you have a few true leaves anyways. keep nutes very light if not just PH'd water for now till first true leaves then can introduce nutes at 1/4 strength and slowly increase from there.

cheers for the advice
