Today Sunday? I'm not familiar with the products. What's generally in the nutes? I'm interested to know what you're adding to your soil. I hope it gets resolved by the flush.I wish I knew what the cause is! I usually get yellowing of the lowers later in flower but I'm losing a lot through stretch on this one.
I am in soil and I'm trying different formulations of my nutes to see if that helps. Maybe the MC is too old or too wet in the bag and my measurements are off? I'll probably flush Sunday morning and reset with a new mix, replacing MC with Blue Planet Max A and B. I have a lot of choices to hit my targets.
