The plant sprouted on the first of March, went to flower on 4/20. I have been a little concerned that the plants would get to big before the end. This plant was my fastest grower, but now the other two adult plants are passing it. It is about 2 feet maybe a little taller. Lots of bud sites and the top of the plant looks ok to me. The lower leafs seem to have a phosphorus problem and for awhile the entire plant was darker than the others. The problem is starting to progress up and seems like it will continue.
I might have had a ph problem. I am using a ph pen from Apera. It came with a couple solutions to calibrate it. I know nothing of this brand. When I first noticed the issue, I recalibrated the pen and checked the run off with 6.2 going in 6.4 came out with ppm in the 700’s
This has been an organic grow up to now but I am thinking about trying a low dose of somekind of pk booster. I am just not sure how to tell if it’s ph or phos?
My water is from Lake Erie and is around 145 ppm out of the tap. I am Thinking of starting low say use a pk booster to take total ppm to 400 ish.
Thoughts? How to tell the difference ph or phosphorus? What would you do to fix?
One of the other two plants just started showing the same leaf damage but was never that wired green color. Oh and the first plants color is now good also.

Just wasn’t prepared for the nutrient demands going into flower - started adding non organic nuts and should finish fine.
Sorry you never got a response to this; I haven't been on the forum in awhile. Is this still an issue?
Ok thought I would follow this up with what came up in my research.
First my brand of ph pen tends to be decent. So I recalibrated it and the next time I watered I checked the run off. 6.2 in 6.4 out so this is not ph lock out. Turns out ph lock out is not so common outside of labs where they do it with extremes.
Second there is another plant around the same size that is not showing weird phos problems. They both have the same amount of nutrients in the soil.
The only other thing I can think of is that this plant must have sat in water long enough to damage the roots just a little and now in flower as the need for phos goes up it is having trouble getting enough from the soil.
So I am going to try to water even less. I am also going to add some micros to help the roots do their job.
If there is interest I will follow up with results.
