My GG4 Auto has burnt tips and some yellowing on leaves. Just came back from a week and a half trip and RH was 35% and plants were pretty under watered. Is this nute burn? or from underwatering

CalMag or PK issue?
What is she telling me? Before I was thinking of a CalMag issue (upper leafs have "burned" tips and get yellowish). So I added it to the reservoir. Is it CalMag or maybe a PK issue, that resolves in a CalMag issue? See my diary for more details.

Burning Edges/Yellowing and Drooping?
The yellowing has gotten worse and I'm noticing slightly burnt tips/edges and some droop. Could this be burn/deficiency or over/underwatering? A combination? Is there anything I can do to fix this early or is it just a matter of giving them some time and less nutrients? Thanks!
