My setup: DWC rockwool medium, ph 5.5 when feed the plants and it usually jumps to 6.2 12-15 hours later and I adjust it to 5.8. I’m running the GH line (base +calmag, floraliocious, and bushmaster microbe for protection) 600w MH temp doesn’t go above 79 or below 71 and humidity was and issue so I got a dehumidifier so RH is now 40-60. I run a 6 inch online fan no carbon filter yet.
First time grower and I do my research before I ask questions. I can’t seem to find a definite answer and solution for my problem. I first noticed this on one leave and it’s been spreading and I now see it on other plants. I just put in the “transition to bloom” mix that has more phosphorus yesterday. Hopefully that fixes the issue.
I saw but marks on some of the leaves so I’ve started Neem oil treatment and I’m 3 days in on that. Are they connected to the leave discoloration?
Any diagnosis or suggestions?
