I am growing a tangerine dream auto in fox farm ocean forest mixed 50/50 with fox farm coco loco. I’ve only given her protekt and water ph’d down to about 6.3. I started to notice these yellowing leaf tips the past week or so at the top of the plant and these brown spots on the bottom of the plant. I was initially thinking nutrient burn from the hot fox farm soil but the yellowing started only recently. The brown spots look like a phosphorus deficiency. I do have a seedling heat mat running under the pots which I’m wondering if it is keeping the roots too warm and causing the yellowing at the tips. Any thoughts on what it could be causing the yellowing?
