whoa dude, cut out the nutes and just use plain water. Also turn off 2 of those 3 lights. You're 2 weeks away from 1/4 strength nutes.

I concur. They already have all the stored energy they need for the first couple of weeks, and watering with nutrients can badly burn or kill them. All they need right now is water with corrected pH (5.5 - 6.0). Then after a couple of weeks start out with 1/4 strength nutes.

italian04, Its best to soak those rockwool cube's in the correct PH water for a while before you put the plants in.:thumbsup:

[italian04]

thanks for the info guys. unhooked the pump and just fixed up a ph corrected spritzer. should i just squirt them 2-3 times a day?? this is just our practice run so i didnt soak the cubes this time. once my northern bright seeds come in i will do that. also is 85F to hot for the room?? i have a good size fan in there so it really doesnt even feel that hot at all. humidity is at 60.

Hi Italian
Let clarify my post about rockwool .
Rock wool is unstable when it comes to PH the reson to soak them in water at the corrcet PH is to make them more stable, I soak mine in PH water at about 5.5 to 5.8 overnight and then let the exsess water drian off before use.
Rock wool is a good media for holding moistere so dont over water.

ya i understand the ph part. kinda worrying about the temp. and when should i start to use cal-mag?

[Greenthing]

Daytime temperature within your growroom should be 21-26.5 C according to the book i read, it can rise if you use CO2 between 26.5- 32 C in the last two weeks of flowering the daytime temps should be kept 21-26.5 C and Co2 reduced to adjust for the plants lower metabolism, night temps should be kept above 15 C to reduce
stem elongation.

well it feels good in our room but temp says 84. the babies look good so im not goin to worry bout it right now. i will keep you guys updated.
