I cannot seem to determine what deficiency I have going on with my gdp grows. The plants are all cloned and spend 2 weeks under t5. They then get potted up and go under mh. After a week or so under mh they start looking like the Pic. Soil is buffered with calmag and I feed fishmix, kelpak and humates and water with calmag. All ph to 5.8. Any help would be very much appreciated
You need to bring your ph up. Your plant will uptake cal-mag better at 6.1-6.2. 5.8 is good for hydro, but pretty low for soil. I’d be shooting for 6.5.
