Hey there mjsticky1,

I see you are growing in a rockwool delta bock, your ph level of 6.5 is just way too high for RW, even for just water flushing. That fact alone will cause nutrient lock-out.

For RW you need a ph of about 5.5, both when you feed the plants nutrients and when you flush them. When you get your new nutrients see what the mfg reccomends for RW.

Some strains in RW will even be happier at a PH lower then that, 5.2-5.5.Hope this mightr help you.
