Masterblend for flower

Anyone use masterblend as their base through the whole grow? I haven't been able to find any good info so I just took an educated guess and swapped out my calcium nitrate and epsom salt for calmag and mkp.

its the wrong balabnce of food from what ive gherd, dont see why as it works great for tomatoes and cannabis have the same food needsapart from the lack of P in it, its packed with potassium nitrogen but lacks enough P

SO YOUVE TAKEN ALL THE CALCIUM AND NITROGEN FROM IT oops, now all you have is the organic masterblend trace nutes and some p and a ton of potassium

if you want to use it, try this
12grams Masterblend,
12grams Calcium Nitrate,
6grams Epsom Salt,
per 5 gallons,
ended with 600ppm or 1.2ec.

The masterblend 4-18-38 has some n in it though. And the calmag has well... calcium and calcium and magnesium. The mkp blend I'm I'm using is 5-45-19. I ran the 12g/12g/6g through veg and early flower. I just worry about n toxicity in flower.

Too much N in the mix will hinder flowering too, it stops the flowers forming as well as they could.
this may be of interest to you.

How did it finish up?

I grow in potting mix as the media, not hydro. I started with Masterblend 4-18-38, but over the years wanted NPK ratios to match what I was reading on cannabis-growing boards and in magazine articles. I wanted ratios like 3-1-1, 3-1-2, 1-3-2, etc. So I started altering their basic formula with various amounts of calnit, MAP, MKP (and S.T.E.M. for micros) to get closer to those ratios (my NPKs are higher, like 15-5-5, but I've used a divisor to reduce and have labeled it Relative NPK).

A few days ago I was checking Masterblend's product line, and it's been significantly expanded with a lot more NPK variants. Were I starting today with it, I may have chosen a different blend from 4-18-38, though I would need to study their NPK ratios more closely to be sure. One of their blends is 10-30-20, which should work well during bloom.
