First time poster, long time reader…
I am growing (2) GrandDaddyPurple which started in PH’d Rockwool then transplanted in Happy Frog Dixie Cups now in 1-Gal containers which will be transplanted again to a 5-Gal container in a week or two (I hope).
I am OCD about PH and I maintain 6.3 - 6.5 confirmed with two meters and old school litmus paper.
I am running (2) 300W Meizhi LED lamps at 24".
As with my last few grows, I am using Fox Farms standard course and I am partially through week 2. In addition to the nutrients Fox Farms recommends for my particular soil; I am also adding CalMag. I feed them only when they look thirsty and I am also using a Wireless Soil Monitor which has been calibrated.
My temps inside my tent are 76 - 80 @ 45% RH
I am concerned because the new growth on both my plants is becoming twisted. They have had red stems on the leaf branches since birth but I am more concerned with slow growth and twisted growth.
