Adding nutrients

Ok so I change my nutrients every week, I read a lot on the net. Get conflicting information, do I water straight RO water or mix nutrient water at 1/4 strength per gallon and use that to replace the water used. If so my plant uses 1/2 gallon a day, in a week I will need approximately 3 gallons of nutrient water at 1/4 strength and on day 7 is when I change buckets. I use soul/roots organic nutrients and follow the master soul feed chart. I have made the decision to remove the bio force as it makes a slime on the roots.

Recirculating feed set up ? Drain to waste?Regardless ,at the end of the week or if you run out earlier, you should start a fresh batch of solution. Also ,check the ph daily and adjust as needed.

It’s a recirculating system, now if I make new solution and change water on Sunday by Wednesday it needs more nutrients I should change then? If so how do you keep track of what week veg or bloom your in to follow a feed chart, sorry I really don’t know what I’m doing I’ve gotten lucky so far

Dont use straight ro water it has nothing in it plants will end up feeding on them selves sounds like recirc system hook up a rezzy to brain/sump tank with bull float as water is used rezzy will refill brain/sump
