15 gal airpots. Watered every day if needed. Ph of nute mix is usually 6.5. I have one plant in a 20 gal regular pot doing the same thing. My PPM's are around 1000 and I fertilize twice and water on the third day
My leaves develop brown spots late in veg and it gets worse through flowering and the eventually get crunchy and brittle. Anyone know what's going on? I'm using ro water and Humbolt county's own nutes and fox farm soil.
