Last week (2) - I noticed yellowing of new growth, higher ph locking out Fe was my diagnosis. I attribute the high ph to the addition of DiatomEarth (+H2O) as a Silica supplement. DiatomEarth= ph9+. Corrected the ph through feeding @ 6.0. Contemplating experiment with FIMing (depending on continued health).
FIMMed 80% new growth @ 5th node. 12 hours later, no signs of distress, "wounds" healed/closed. I spread out the remaining 20% foliage to promote separation. Looking good so far.
Great growth post FIM, no sign of stunt/delay.
