hopefully the two that i just put in will grow a bit better ive put humidity domes over all three of them now i turned the fan off and
i'll use non ph water , i get about pH8 we have really really soft water where i am but i dont know 8 sounds high.

Im using ecolite 1%charge coco70/30 perlite and I keep the ph between 5.8-6.2 you want to keep it in that range in my opinion when using coco

it not that crispy i had 600 further away but much more heat ad it for and swapped it for a 400 is 25"-30" still too close for a 400w hps, is it cos i have such a simple light with no fan attached to it? ive got a fan blowing on them and when i put my hand on the soil its not hot at all it actually feels cold.

Think that's the issue your having is the ph levels and over watering.... I would lay off the watering and ph your water and only water when need and not over do it. Remember less is more

im using coco 70/30, cal+mag buffered it said on ebay i emailed them how long calmag should last in the mix and they said 14 weeks. :/

im thinking of taking the 400w out and put the 600w back and raise it to like 40"-45"
EDIT: and instead use tap water left out for a few days instead of the ph 6 ive bin using, start from square 1 again . i think i tried to jump ahead too quickly so much conflicting information out there

The wet spot (that sounds funny) should be 2" diameter if you watered directly. She us definitely watered. Dont water again until the medium is dry at least 1/2" down around the perimeter of your humidity dome. I think dont press the dome in. Just set a clear done on top of the soil. It will raise the RH bit still allow some air. GL
