Help Please, calcium problem I think.

[Bigger_Nugz]

She’s had a calcium supplement but is still showing signs of deficiency. What’s going on, what should I do, I’m a new grower, the other 3 plants seem to be fine. Her water PH at the runoff was 6.7. I think that’s a bit high, should I flush her with some 6.0-6.1? Any help would be greatly appreciated.

flush and renute add back microbes

checking ph run off is a waste of time and probably fucked with your head trying to figure out what to do with that run off number.
Hint that number is worthless. Microbes regulate the ph at the root surface.

get some microbes

I'm new to diagnosing nutrient issues, but too much Ca can lock out other nutes such as K and others. That looks like it could be K deficiency.

This is the chart I look at to help me.

Ok so I flushed with nutrients with a ph of 6.13 so hopefully it will clear things for me.

If you have severe lockout and nutrient build up run-out ph will be very acidic from my experience.
