First, the details
-3 weeks into flowering under (2) 400 watt HPS lights
-COCO COIR w/ Hydroclay watered 3 times every 24 hours
-Lucas Formula GH Micro + Bloom, w epsom salt, florablend vegan compost tea. Distilled water, PH balanced.
-PH is always 5.5-6.5, humidity around 50
Ok, now onto the pics, and my thoughts on their diagnosis. I really need your help guys in figuring out why my plants keep losing their lower fans to this yellowness. The leaves first turn yellowish with purple stems, then they shrivel up and are dead within a week.
According to my Book on growing, the leaves look like they are suffering Phosphourus deficiency, because dark blotchy spots occur on some of the leaves. However, the plants are being dosed with 16ml of Bloom, so how is this possible? Is there a nutrient block out of some kind?? What can i do??
