Dwc feeding/tips

Besides your basic nutrients, I recommend calmag, hydroguard, and diamond nectar. Calmag I'm sure you know all about. Hydroguard protects the roots from rot, especially important if it's going to be warm in your space. Diamond Nectar is humic acid, and increases uptake of micronutrients. Hydroguard is the only one I use right away, all of my other feed I introduce around the end of week 3. If you're worried about a warm res, put your pumps in the coolest part of your grow space. My tent is in an air conditioned room, so my pumps sit right by the vent. My pumps blow cool, fresh air into my buckets. My diary is my first DWC grow, check it out. I made plenty of mistakes and documented them all. It may help.
