6/19 - The plants all entered flowering this week. Right on schedule with what Growers Choice says about the strain. The new light is incredible and is finally at 100% power. The plants have really responded to it and growth has picked up. The insect issue from last week seems to be handled. All yellow glue boards have caught many flies and there doesn't appear to any further damage to the leaves. I did a heavy flush on all four plants today per Fox Farms nutrient schedule. The PPM went from around 2000 to 150. pH stayed at 6.5. The plants started displaying signs of magnesium deficiency on the top leaves, had to confirm this online of course. After flushing, I gave a normal watering with pH 6.5 with 5ml CalMag, plus foliar spray of the same solution to get in the plants both ways. I did some "reverse" LST on one plant. I originally LST'd this plant too far outward, so I wired them back to a more vertical position. I also defoliated the bottom third of leaves and all leaves that were blocking lower bud sites on top. 6/21 - Fed the plants their weekly nutrients. Calcium deficiency has whooped the plants asses! I'm using CalMag to bring them out of it. 5ml per gallon on every watering. 6/25 - The calcium deficiency seems to have passed. I kept calm, and fed 5ml. CalMag per gallon all week. CalMag foliar spray twice during the week, one on Monday and then again on Wednesday. I trimmed as many damaged mature leaves as I could see. All new growth seems to be unaffected by the calcium deficiency, though they are slightly twisted. The leaves still have deep grooving in the veins of the leaf. I'm not sure what causes this, and they seem to be growing and developing pistols like crazy. Is it possible that the leaves change as the plant matures? And as a real bummer, all new growth tips have nutrient burn!!! The Fox Farm bottle said up to two feeds per week and I got greedy. Going back to one feed per week. So, there have been a few set backs in the last two weeks. Between the gnats, calcium deficiency, and now nutrient burn, the plants have been through a lot. Hoping for some stability in the plants to finish things off. On a side note, I'm not using Coco next time, being void of calcium in the first place and the need for so much flushing, I just don't think Coco works for me.
