Need a couple diagnosis’

[Waira]

6.5 is fine IMO, depending on how your soil tends to change as the grow progresses,... and keep in mind the A8 is +/-0.2! ...Most micro's start to lock out as you get near 7.0,... you just may have been short on them, and/or the roots were pissed off for a bit,.. ... the fastest way to treat is with foliar sprays (along with soil dosing) with the micronute supp', plus a wetting agent; this allows your spray to coat and stick better, not just bead up and roll off,.. get tops, and bottoms especially of leaves,.... if you want max-ass kicking on this, Optic Foliar Transport is bomb stuff! used with the micro-supp', no wetting agent,... no need to get bottoms either, since the Transport allows temporary penetration through the leaves cuticle layer right into the working tissues! Check out the older Showcase item I did on this for details,...
the A8 should have some instructions on the cardboard backing of the package,...
