Phosphor? wind Burn? my Leaves crisp up!

I would double check the pH. Could also maybe be low on calcium. But make sure your ph is good, because that can have a dramatic impact on nutrient availability. Or maybe even if you can add some humic or fulvic acid? Humates can improve nutrient uptake. The splotchy pale green almost looks like an early onset of potassium deficiency. But being on the new leaves, I’m not sure if that’s right, could actually be magnesium. Maybe just a little extra CalMag. Calcium without any magnesium can potentially start a magnesium deficiency. Maybe even some CalMag with a little Epsom Salt (Magnesium Sulfate) could make a big difference… I am still learning too. :) Best of luck
