medium = DWC

i really like 5-7ml chem // 5-7ml calnit // 2.5-3ml mag-sulf per gallon. Im testing this formula all thru flower. Im on week 2 so no results yet.

another test would be 5ml chem // 10ml calnit // 2.5 magsulf per gallon just to see if this fixes the calcium issue.

mrrangz, somehow i've missed your post. from what i am experiencing slight bump in both calnit and magsulf makes a difference, but that is in coco with RO. your results in dwc might vary. please keep up posted with your results. do you have any pictures?

mrrangz, those are healthy looking plants. looks like one with more calnit has little longer internodal spacing and looks bigger.

how was your run??

I've switched eventually to master blend 4-18-38 because of the price - it is almost 40% cheaper and formula is not that much different.

we finished a run, but had some issues with deficiencies. will try to correct it next round.

the extra cal-nit which was supplying 150ppm Nitrogen and 150ppm Calcium was good, especially for the cal content, just too much N . So im still using calnit but im using less of it and adding cal chloride for a Calcium increase with out messing with the N ratio.

the N that got lowered with the use of cal chloride, allows me to add extra chemgro for a PK boost.
