deficiency?

Again, that's a very rare deficiency to have. It looks like your problem started at the bottom of your plant. This means it's a mobile nutrient problem: nitrogen, potassium, phosphorus, calcium, or magnesium. Boron, sulfur, iron etc are all immobile nutrients so the problem starts at the top leaves. You are using Floramicro, so you shouldn't have micronutrient problems. Always mix micro into your nutrient solution before gro or bloom. Dissecting your journal, I notice you have no calmag supplement. Calmag are vital for your plant to live. Looks like you have a calcium and magnesium deficiency. The problem starting at the bottom supports this conclusion. Get some calmag, I recommend CALiMAGic @ 5ml/gal. If your journal is accurate, I am 100% sure this is your problem. Good luck.
