I’m a complete scrub to most growers here, but 40 ppm sounds way too low after 30 days, no?
Lowering after stretch makes sense from what I’ve gathered here on f4200, but it does seem to be asking for problems lowering this much.
This is exactly the problem with this article/research. How many growers will leave after reading it getting that impression?
My understanding 40ppm is for DWC and hydro/coco none is needed IN ADDITION to base levels.
DWC really isn’t that commercially viable so the research is ultimately not that useful anyway. But since it says it will smoke better I’m curious how many people will be lead down the road of un-smokable bud rot.

after the 30th day of the flower We cut calcium down to 40ppm. Nitrogen will be around 30ppm, but our K number goes to 120ppm. Will there be an antagonism with calcium or not
