Day.21 flower. All good so far. Buds filling up the colas. A little amber amongst the white now. This being the longest flower time of my 3 I didnt expect it to be the most developed so early. Fed and watered today. Day.24flower- seeing a cal mag deficiency again, same as the nl. Fed and watered today. Lowered ph to 6.1 as ive read promix tends to ph up over time .Maybe locking out or just needs more. Had laid off cal mag a bit last few feeds so i could keep ppm down a bit but it appears it cant do without. Day.25. Seems to have affected some old growth fan leaves first luckily, and not much else has continued to happen today, so i think i got it in time. Day.27. Fed and watered. Keeping cal mag up. Seems to really like it.
