Phosphorus Defiency? Nute burn? Tons of pics

Hey guys, Im in coco feeding at about 1.2EC on the truncheon and PH 5.8-6.0


Ive been noticing interveinal graying on bottom leaves, but am beginning to see it on top leaves. Bottom leaves are also curling downwards.

Probably but im bad with deficiencies
phosphorus deficiency is usually purple ish in most crops

It does look like P but I have to ask, what type of lighting are you using? Your plants look starving for light.

looks like p yes it does check your p.h

problem looks to stem from a water logged medium, which in return is causing the deficiencies. let that medium dry out a lil more between watering/feedings.

i know you may be saying to yourself, it's impossible with coco, but it definitely looks like the case. until the roots take a nice hold of the medium, you must water accordingly.

Change nute brands & increase ppm, check incoming water ppm, double check your ph with a chemical test, looks like you need stronger light if you are using cfl's add hid.
