I am gonna lean on a ph out of line in substrate due to plant is absorbing lots of potassium and phosphorus. Raising ph as it eats. Now causing first signs of lock out for both those nutrients. I don't feel it's cal mag all in your case.
Organomananswered grow question 4y ago
It is not cal/mag, but burning from feeding too much or too often, or both.......as evidenced by the super green foliage in general.

Should I flush? (Overfeeding)I think I have overfed my 2 dwarfs. Theyre showing signs like very stringy skinny new growth and yellow leaf tips. Theyre still growing and I dont want to stunt their growth, so all I want to know is if it is necessary to flush. Please tell me how to flush if so, thank you.
