So, i believe this is a phosphorus def, but not sure. My hijack auto is 28 days today and is showing what I believe to be a phosphorus def. % of stems turning purple is increasing. Show slight leaf discoloration (major leaf discoloration on one of the older leaves at the bottom). Just fed 1/2 FF trio nutes last night. Previous two feelings were @1/4 strength. Has been in flower for about 2 wks now and I feel that the growth is a bit stunted. I thought that maybe the vertical growth stopped to focus on bud development, but I haven't noticed bud developing in a few days. Pls advise...

I figured I'd still supplement not knowing how much ca/mg was in my tap. But I mean, that shouldn't have any ill effects on anything though, right?

Keep the use of Ca/Mg going......You simply don't know exactly what is in your tap water...

Not a P def I can see......Your plant looks great and doing well......The "damage" you highlight in your pics indicate it looks to be a natural low area die off.....No worries!

Consider switching to a "clean" water like RO......if you think you need to in the future.
