Phosphorus issue?

I think is phosphorus and I’m not having much luck stopping it. Two other plants started like this and Kept going. I have some bone meal and made a gallon slurry at 400ppm by letting it soak. This did not seem to do much of anything. I also top dressed some ewc and am letting that work. Suggestions??

Blondie 400 ppm of bone meal s a good source of calcium and a lot too and will raise the pH. Its slow so you can expect the pH to go higher or stay high. You can not fix the problem by giving the plant anything at this point.

On watering day after you water your plants wait about an hour and then do a pour thru with about 250 ml of Distilled or RO water and catch some of the run-off out the bottom. Just a little. Test the pH, EC and you will find that your pH is very high and that may be what's causing the yellowing.
