The RO machine wasen't bad, probably $300 total, and that puts the drum next to my work bench thanks to an extra long hose.

Im gonna go give them plain tap water 1 last time before I start feeding them again. Baised on what I understand, I should give fertilizer in water once a week for a week or so before switching to every watering, right?

THanks again
No need to adjust....

(let's stick to per gal for now)
5ml per gallon of PBPG = 590 - 600ppm
5 ml per gallon of CM = 225ppm
5ml per gallon of LK = 70ppm

So after looking at what the ppms are for each different bottle, we can see that even though we are giving the exact same number of milliliters, the ppms differ....so this is why I say that your N-P-K will always be given at higher doses....now ya get it???

Now let's add those numbers to see what we get.... 895ppm is what we would have if we place 5ml of each of those in a gallon of RO water.... But we want to be at 300ppm per gallon on week 2 of veg, so we divide.... Then once into flower you simply replace the PBPG with PBPB.... Just remember not to give more than 5ml per gallon of CM, anytime.... It's up to you if you want to give more than 5ml per gal of LK at any given time....the recommendations say to do so, so that one is up to you....

You don't want to give ferts with every watering....give plain RO water between feedings....

pH is pretty important too....you got that covered???
