I have two 1gal bottles for each of the three nutes and rotate as needed. Only 3 shown here, the other 3 are on the floor of the greenhouse in the shade.
To each bottle, filled 3/4 full of tap water I add:
#1 78 gms of Master Blend
#2 38 gms epsome
#3 78 gms calcium #3
to each bottle and fill the remainder of the bottle with tap water which is 7.0 pH and 225 carb hardness.
I have 3 one qt bottles that I use to mix the nutes into 1 gallon of fertigate. With coco you're always "fertigating" not just watering BUT you never want the coco dry out. The plant will suffer even if it's just a day or two.
This one gallon of nute water can be made weak, med and full strength by the amount of the concentrated nutrients used. 4 oz, 1/2 Cup of the 3 concentrates, and they must be mixed in order or lockout problems will occur, is the full strength amount that I give to adult plants. 1-2 oz per gallon work well for most herbs and Kratky hydro

I grow lettuce in the winter in Kratky, and young plants 8 days old to 3 or 4 weeks old.
3 oz per gallon is what I give most plants in veg and 4 oz is a full amount designed for Tomato Plants.
It works for weed real well if properly done and that's 3-5 x's a day, completely saturate the coco coir and have 10-20% runoff and again never let to dry out.
That's a lot of waste water but this is a tested, tried and proven way to produce dynamite smoke.
From seed to first 7 days only water, only. Easy to burn the end of those new leaves and stunt growth. Do Not Recommend, 0 stars.

Cost is minimal using MB with the other 2 and none of the liquid ferts I know of come in powder so you pay for the water.
As you can see MB us very versatile in catering to the needs of plants of different ages and kinds.
I've been growing in it 5+ years after a lifetime of soil in the ground, in the garden, under trees back in the day and even soil pots in a closet early 80's. That grow cost me as much as a pound and didn't produce more than a few ounces

Today I got big bags of somke, all the time
I just finished last fert, used almost 7 gallons of full strength in the garden, that's about 20 gallons when used 3 x's a day and almost 4 gallons in the greenhouse of a 3 oz mix so 10-12 gallons a day for 30-34 gallons total a day. I use to do 5 x's a day when i had both greenhouses on auto. Story for another day
Ya wanna grow big plants fast coco and hydro nutes rock.
