Pineapple Express x2 & Auto Durban Poison x3

Pineapple Express (PE) x2 & Auto Durban Poison x3 (DP): This week They have grown a lot. PE #1, #2, & DP #1 all had dark green leaves with a waxy look. DP #1 even starting to show some white tips on new growth and a few white spots. This is a sign of Nitrogen Burn. Watered to run off to cool things but I feel it's not such a problem. They are still green and growing so I'll leave them be. Accidently pinched a leave on DP #1 marked it pretty good. Transplanted PE #1 & #2 into 3 Gal Pots. Transplanted DP #1, #2, & #3 into 1-Gal pots. But later up potted DP #2 to a 2-Gal tall pot once it flowered. DP #2 seems to be in flower very early (Day 33). Sohum Living Soil for Cannabis thus far has been a good but Hot soil. Retains water well. I've watered to run off then don't need to do it again for 4-5 Days. Currently hitting them with 18/6, 800-850 ppfd, RH 53%, Temps 75-80F, Ambient CO2 550-800ppm. FIMed DP #1 seems like there are 2 mains now. Topped DP #3 for 2 Colas as well. Practicing techniques.
