Could never figure out why so many have issues with FFOF. Other than some regional differences in sources of the elements used.
FFOF can run a plant “ all the way thru “ a grow whether auto or photo. Medium will begin some exhaustion after 6 weeks but can be RECHARGED with a simple top dress or Tea / Soil drench. You just keep medium charged at intervals of grow. Not rocket science .... no need for distilled ( another head scratcher on use ) ... yes distilled can remove things like crypto / lead / pathogens etc.
But .... it also removes lots of dissolved solids like calcium / potassium and other trace elements. Which ironically the grower has to “ ratio “ back into it by way of feed or supplement . What other plant on earth NEEDS distilled water ? Outside grass , bushes , other plants dont give two shits about the water. Even the chlorine extraction pulls that element - and plants DO USE chlorine in some plant processes . Its just a plant .... no magic involved... no unicorn sweat or magic pee water.
Tap / city water works fine.
Big bloom is the only organic of the 3 ( trio pack ) and is a supplement to the bennies in the soil. It can be used throughout grow but not alone. The addition of fresh FFOF will charge the host soil and allow the big bloom to “ complete “ soil with ewc / kelp and other micronutrients.
IMO .... add more ffof ... water in ( tap ) ... drop ph 6.5 ( to allow for minor drift ) - FFOF is ph’d at 6.3.
FFOF will add more of what is being pulled from host soil WITHOUT guessing ... since plant has already acclimated to it . Spots are from the calmag deficiency... led grows often need a bump at times.
