Ppm in runoff higher than feeding
The run off ppm is around 500 and when I watered it it was around 200 ppm. Ph levels are fine. Does this mean it’s not getting the nutrients it needs? How can I solve this?

Yellow leaves
my little GG2 is starting to lose many leaves (they turn yellow and fall even before drying) while the other is not having any problems (the only difference between the two is the "aggressiveness" used in the LST) it could be due to the flushing done (but less than 5 days ago) 🤔

phosphorus and boron anomaly
Could someone please explain the precise mechanism underlying the phosphorus anomaly? As anticipated, availability decreases with increasing pH, yet it exhibits a sudden surge at pH 8.5. What is the exact (bio)chemical rationale behind this phenomenon? Boron has a similar pattern

Potassium, correct?
I think this is the beginning of a potassium deficiency. The near neon green discoloration is what caught my eye. This leaf is affected the most. Second week of flower. The Alga Bloom was just increased from 2 to 4ml/l earlier this week, so she should be alright. Right?

Add CalMag or Manganese? Still slightly discolored and veiny leaves on week 6
Calcium or Manganese deficiency? Last week had what I thought was early calcium deficiency. Gave it a dose of CalMag but now not sure if it’s still Calcium or possibly Manganese. I do mean manganese but I realize it could be a CalMag or Manganese deficiency as well.

Cal Mag deficiency. Should I put it to flower?
Will the plant recover when it reaches this level of damage? This plant is at the end of vegetative growth. Is it okay to put to flower, or do I wait out? Many thanks.

Is this a K deficiency? Otherwise good at 47 days?
First grow is looking good. Started supplementing P and K a week ago - noticed signs of K deficiency today. Lower leaves yellowing, red leaf-stems. Should I just keep stay the course and keep the nuts coming?
