Meizhi 450 watt

Flushed the plant on day 37. Feed as posted...since my fan is blowing thru it is really turning purple.I still haven't received my ph meter yet but got my buddies and went to Calabrate it and got a reading of 7.4 on my water and then tested vinegar and got 3.6 not 2.4 then the ph meter wouldn't turn back on so I'm taking a guess and saying my water is at 6.i decided to feed one nutrients each watering to catch my ph without using ph up or down..The CM is looking a little over watered but really showing color.Nice purples on the flowers, leaves, stock and stems. March 2nd. I flushed My Pineapple express today all of the ladys were showing signs of nitrogen toxicity. The leaves were dog legging and the tips went Into a sever curl downward after after a light watering.
