Flush

How often should you flush your plant? Im starting my fifth week of flowering and notice that some of my fan leaves turning yellow, shriveling, and falling off. Dont know if its because its in the middle of flowering or something else like salt in soil or low ph.

you should alternate feedings and tap water. it avoids salt build up etc. and for the leaves yellowing yes it's normal in late the late flowering stage.

i flush ever 3 to 5 weeks and always 2 weeks before harvest.

when in doubt, flush it out.

always flush during the transition of veg to flower if you used veg nutes and I flush once every few weeks to keep the soil fresh
