So I use Jack's 321. I read recently that lots of nitrogen in flower is bad because it causes more leafy buds. But that I need calcium in late flower to help avoid getting bud rot.

If I drop cal nit and espom salts in 4 or so of flower. Can I use botanicare calmag and potash of sulphur to make up for the lack of?

Jack's 3-2-1 is designed to be used all the way up to flush week. Organic soil doesn't change the nutes available drastically and Jack's doesn't have to either.

If you feel like fiddling with success, try something that also works well in flower:
Weeks 1-5:
3 Jack's-2 Calnit-1 Epsom
Week 6-
3.6 Jack's-2 Calnit-1 Epsom
Week 7-
3.6 Jack's-1.2 Calnit- 1 Epsom
Week 8+
Flush

I thought nitrogen at that level would have a bad impact on bud growth? The last few runs I've had I had better bud formation with less nitrogen. But got some bad stuff from lack of calcium..

I am reading right now that alot of calmags use calcium nitrate for calcium. So I'm trying to find ratios to drop the calnit that works for less leafy buds.

I'm using MasterBlend, in wk 9 and have dropped the calcium to half strength the past month. Seems to be workin ok.

The MasterBlend is cheap and being 3 part easy to adjust.

Calmag is literally calcium nitrate and espom salts. Thanks guys but with hydrobuddy and some older posts I've put together my answer.

Bill that's why I'm trying to figure this out but I think I may have it now
