I've been feeding around 800-900ppm for full feed and around 400 ppm for a lighter feed. PH water between 5.7-6.0. It looks like nitroGen deficiency not sure what do u guys think this is my first time with this strain I've never had yellowing this early it started around week 2. It is day 19 of flower any suggestions on what I should do?
