What should PPM be at beginning of flowering for GH flora nutes???

I have my plants in a ebbflow hydro system and I have had my PH at 5.9 and 5.8..when I follor the nutrient calculater on the site. My PPM is way higher then what they say it should be on the site?? My plain water is on 70ppm. My ppm has been around 1400 and 1500. My plants seem like they are dying. I am not sure if it is from to many nutes or not enough. All my fan leaves are dying and plants turning yellowish green. I have been trying to get then healthy since I put the clones in my system six weeks ago. I just switched over to 12 and 12 last week. Thanks for the help

What PPM using GH flora nutes work for you??

Hi,

I started my 1st grow with GH and did a very similar same thing. Waterfarm journal.

What I would do is #1 I would run clean water Ph at 6.0 for a couple days and flush them. Then look at the water level. make sure the level does not totally submersed the rockwool cube (I assume you use them) Just touch the bottom of it.

Next after a few days I would use nutrients at half strength. In my experiences that all they really need. Keep Ph at a little below 6.0 and once flowering a little over 6.0 like 6.2 be sure to ph after adding nutes.

Good luck man.
