WulfBlud
started grow question 3y ago
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.

You probably confused Manganese with Magnesium.

Am I about to give my plant a nitrogen overdose?
Today I noticed that some of the leaves tips were curling a bit down, being a bit darker and they seem to have some wrinkles too. Could it be nitrogen overdose? How would you correct that? Less fish mix or switch to bio grow?

Not sure about deficiency, thought was Calcium or Magnesium but not sure anymore.
The nutrient deficiency is back so I gave it another double dose of CalMag to see if that can stop it in its tracks but I am not positive if that is the specific problem. Added micronutrients mix as well to see if maybe that helps. Any suggestions would be appreciated.

Ph value is decreasing despite BioBizzUp
I don´t get it I´m trying to increase the Ph value but it is permanently falling again to a value of 4,2. Any idea what could be the reason why my Ph adjustments (BioUp) are not taking effect in the soil. Additional question for SD: What to do with the brown leafes? Remove them?
