Ok, there's probably a simple answer to this and I may have it right now but I just need to check to make sure.
In order to cut down and mixing every day or every other day, I mixed everything into a 15 gallon cooler last night. Next everything up and I forgot to add PK 13/14. I went ahead and fed them without this morning without it. So, to my obvious question....
Is it ok to add that into the cooler the next feeding? I was thinking of pre mixing some in some RO water first and added that way. Am I on the right track or do I just wait until I refill the corner again in a few days?
Can add it or make a seperate res to control the amounts you add seperate from your nutes. Personally I would make it separately just to have some added control. If you find it's to much you won't have to dump your nute res to get it right.
