Fox farm ocean forest soil. 45 days in flower. Started getting these spots and getting worse. I feed them fox farm nutes tigerbloom and a veg one. I haven't been giving cal mag til recently. I'm wondering if it's a calmag issue because of lockout. But idk if that looks like one or not. I ph water at 6.8. The soil is 6.0 and it never raises. I Ph water at 6.8 to 7.3 just to see for like whole grow and it has never raised. Maybe it's possible my ph water meter is broke and not calibrated and it says its 7.8 but really 6.2. I got in new few months ago calibrated it then not since. I just have a gut feeling that isnt issue tho. Run off is 5.5. I need help bad guys. My first 2 pics and all other pics are 2nd plant. Same exact details pretty much but looks much worse. Lights are 250 watt led light 2ft above so that is no issues I'm pretty sure. I know some pics hard to see cuz of light. Sorry any advice at all tho. No idea why ph doesn't raise? I'm thinking this could possibly be lockout of cal mag but idk I'm pretty new so any advice appreciated please Sent from my SM-N950U using Grasscity Forum mobile app
Ocean Forest has crushed oyster shell in it to help buffer the PH. Zero reason to ph your feed/water. IMO that just causes more problems in the long run.
