So I upped my game and bought a the recommended fertilizer and a better PH pen. I have been water with the 321 at 5.8ph to run off and the run off has been mid 6s. I’m still seeing yellowing on one plant so I decided to flush with clean water. I flushed with 5.8ph and my run off on the one plant was 6.8 to 7
No idea why but I’m guessing that could be part of the yellowing. Any suggestions? Should I add stuff to lower the soil ph? I just flushed 2 days ago.
My other plant (white widow looks to be doing fine that’s the last pic. They’ve been getting exactly the same stuff. It’s run off was 6.8.
I’m looking to turn it to flower soon but want to correct anything before that.
