More pictures from today, I checked the ppm 440 and the pH 5.8, I only added nutes at half strength when I refilled the rez several days ago, so without further advice from you guys I just added the other half of Cyco Grow A, Grow B, and some CalMag. pH stable at 5.8, ppm is now 547.
Whats happening!? =(((
Dang leaf on the other plant straight snapped off hanging down... Lol.
The newest growth seems to be okay though - even more confusing. Also I noticed two of the other failed plants have came back to life, teeny tiny but they are coming back! Lol. Obviously the 600watts was too much.
