I have gone through 2 batches of clones trying to get my aero working properly and to no avail! I am using misters along with Iguana juice grow with clones in rockwool. The PH is good, around 5.8. My babies are turning yellow, and not growing. The roots in the first batch started to grow then stopped. In my 2nd batch, the roots have barely began to grow, and its week 2! Do you think it could be the temp of the water (too hot)? Im using a 400 watt metal halide, i have a fan on them when the light is on, and the temp in the grow area is around 88 degrees. I dont know what it is! Nutrient lockout from something? too hot? somebody please help! Thanks
