This is my first hydro grow (top-fed dwc) and it was going great up until this week. The leaves began to taco and slouch (from what I assume is overwatering) and the rate of growth slowed down a bit. They're in 2 in Rockwool cubes and I've stopped watering for the most part in attempts to dry out the cubes. I also lowered the humidity and upped the temperature by a couple degrees. I've just been coming in every couple hours or so to make sure the roots don't dry up. I also lowered my nutrient concentration by about half just to make sure the signs the plant was showing werent early signs of nitrogen toxicity. Any ideas on how to fix my problem? The Rockwool just refuses to dry out and I'm afraid if I can't fix this quick the roots may begin to rot. Any help is appreciated!
