Yes it can. Just don't mix the micro nutrients with macros.

Honestly, as long as your'e staying within the ranges I listed your'e good. So you could do either. That's one of the beauties of the EI method. There is a lot of wiggle room. Often I see people trying to calculate this to death. Just get in the range and your'e all set.

Element ppm/degree
K 7.50
S 3.08

I would be dosing it 3 times a week so that method would be correct?
Yes it's fine 3 x 7.5 = 22.5ppm in a week. The range is 10-30ppm. See the wiggle room? lol

Just mix the macro and micro seperate. Dose on alternating days. Technically mixing the two can cause precipitation. I've never seen that happen and I dose both on the same day. I just make sure each is mixed into the water well before I dose the next.
