Plants are all auto's and outdoors. Plants are almost 5 weeks old and started to flower a week ago....I had been using a water soluble 24-18-20 up until now...I figured starting into flower I better reduce my N...

I bough a bag of jacks part A 5-12-26 for this purpose. I will be mixing in a 2 gallon Container. If I go buy jacks chart and do the math it comes up to 3.68 grams per gallon of water...Does this sound about right for starting at week 4 flower's just starting?

I also plan on adding a tad of Epsom salts according to jacks mixing chart....and a little calmag when it arrives in a few day's

Newb here guy's...Any help is appreciated!View attachment 4948523

I though much N was bad during flowering? I guess that's why jacks 321 mix calls for jacks 15-0-0???

Full strength is 3.6g Part A, 2.4g Part B, 1.1g Epsom Salts. That's what I use at reduced strength along with ArmorSi.

Sounds good, but do you have 15-0-0 Part B? I wouldn't recommend adding CalMag.
