First Dro Grow

FIM/defoliate at end Wk 3/start of Wk 4. Re-test PPM and pH, adjust pH to 6.0 again, post-nut shot. Note1: all nut levels are actually mg/L, powder, mixed as recommended by PowerGrow. At this point, however, calculating nut shots with algebra (use of the formula: [ppm = m/V]) is used more to keep nuts in check. Target is 1500 ppm, but it never seems to measure that way (12g Master + 6g Espom + 12g CaNitrate = 30g = 30,000 mg dissolved in 5 Gal ~= 20L ==> ppm=m/V = 30g/5gal = 30,000mg/20L=1500 ppm. I should probably calibrate my ppm meter, but I am working off of relative ppm for now. Light cycle increased late Wk 3, now that roots are well developed in the DWC. Increased light distance to see if the plants stretch more, as nodes are quite tight. End week 4: just kinda let everything grow to recover. Began observing for sex traits (see pics).
