Auto Glueberry O.G. DWC

Week 2! Steady growth. Roots have finally hit the reservoir. Upped the nutes hoping to push the plant a little without causing burn. 4/25: ppm = 502 pH = 5.7 Temps: 63 - 73F (a water chiller is on the way!!) :) * While the top of the plant looks slightly worse for the wear, roots are really beginning to to start emerging from the large rockwool cube and hang into the nutrient solution below. I'm new to hydro, so any help on something like a ppm schedule for an autoflower would be much appreciated. If nothing like this already exists, I'll keep track of one of my grows and post the ppm schedule I used (if the grow goes well, haha). Cheers!
