concerned with the health of this plant

Blue mystic, 60 days old

Looks like a phosphorus deficiency, feeding any nutes?

have you tested the run off's pH?

Feeding w/ GH trio - 2ml of each per gallon. Ph of water is always 6.5.

My ~50 day old haze auto isn't doing very well - here is a leaf that fell off this morning, im feeding it light nutes as well.
