Amnesia Auto - 2nd grow

And we go downhill from here boys. Started to show signs of calcium deficiency (if you r reading this please help me confirm whats wrong) which will get worse and worse. Bad idea for me to add more nutes which included calmag. The calcium deficiency I think may have come from nute lockout in the roots from phosporous toxicity, from flower fuel?. Decided to flush and the end of the week. Also, this week I started to use a dehumidifier to get RH down to 40%. I also started a new grow of Northern Lights Auto in the bottom right of the photo. Btw, was very happy with how LST turned out so far. It really helped control the growth and making new bud sites without hindering the plant. Week 7 ——————————————— Mon 9 mar - 3L water (superbud flowering), am12 show signs of calcium magnesium deficiency, yellow brown spots on leaves (bad idea here to add more nutes) Wed 11 march - 2.5L water.
