Need Help Identifying Deficiency

[Hoang]

Any help would be appreciated... I have recently switched to the lucas formula for this plant (6/9 in coco + epsom slt)

and symptoms seem to have improved, but what is causing this?

Nitrogen def. Never seen that happen with coco + 6/9 . Did you flush the coco thoroughly before using it?

 

[Hoang]

Yes I did flush. Was previously using floranova. Hopefully the switch to lucas 6/9 flora series will save the plant.

Sure would be nice to see how the whole plant is looking instead of leaves plucked off. I see P-, to start.
