hello, aeroponic system with reverse osmosis water and from the beginning I have a problem with calcium deficiency, vegetation lasted 3 weeks, flowering 3 days
I use masterblend 4-18-38, calcium 15.5-0-0 (19%) and epson salt and add monosilicon (power si) and amino acids
Co2-1400
ppfd-1000
RH- 65%
I choose masterblend 4-18-38 [2g-3g-1g/gal] please help me thank you
But could be caused by too much calcium and magnesium is locking out. I would ditch the calcium and epsom at next reservoir change and use a commercial calmag solution. To easy to get things out of whack in hydro when mixing your own brew.
