Ok so I have been on this forum for several months and new to growing. I have research and research again and read so many different things.
Here’s my problem. The tips of the leaves on my plants are turning yellow with a brownish tint to them. I thought it was a calcium deficiency and slightly increased the Calmag+ when I fed them yesterday morning. When I checked them a couple hours later the yellow was slightly worse. Then this morning it was even worse.
I am growing in Mother Earth Coco-perlite 70-30 and using Canna Coco A+B nutes. I am using well warer that I had tested and it has a ph of 5.7 with 40 ppm tds.
I started with 2 ml calmag per gallon and when I saw the yellowing tips I increased the Calmag to 3ml per gallon. The yellowing continued so after a week I increased the Calmag to 4ml thinking that since my water was at 40 ppm it needed more. Increasing the Calmag has not helped.
My nutes are mixed at 800 ppm since the ppm of my water starts at 40ppm including the Calmag and ph up to 5.8 - 6.0. I check the run off and the ph is within 0.2 of what I feed.
I am running 1000w hps lights and they are about 24 inches away from the tops. The temps are at 75 degrees and I’m running 800 ppm C02 in a sealed room.
My ladies are not looking good at all and I’m trying hard not to kill them and I need help please.
