I have 9 plants and 6 of which are just beginning to flower. I will need to be using nutes as they are growing in pots outdoors and not in the ground. I have the FF trio of nutes and the medium is FFOF that’s about 6 weeks into my grow but my question is if I mix at 1/2 The rate the bottle suggest as most of you have told me to do so starting off. Should I mix a gallon of water worth and use the whole gallon on each plant or maybe mix a gallon worth and use half gallon each on 2 plants and so on. Just wasn’t sure exactly how to do it. Also do I wet the whole medium first before adding the nute mixed water or what. Sorry if any of this sounds as if I should know this but I really don’t and usually only get a few responses to any questions I have if I’m lucky so I’m just kind of winging it. Also does anyone flush occasionally after a few feedings to prevent salt build up or only flush prior to harvest. Just learning as I go and isn’t always the easiest thing to do. One more thing is there anything else I can add to help my plants besides the nutes I have? Heard certain types molasses helps but I don’t know which ones or if there’s anything else I can add above and beyond what I have to help bud that won’t creat nute burn or has a low risk of it. Thanks to anyone who might be willing to help me. These are my girls a week or 2 ago.
I would mix 5gal at a time because they probably won’t take whole gal
I also think I would start by mixing up 5 gallons for all the plants. You can always adjust if it was too much or not enough. Mix and use, it settles if it sits too long.
I would do the flushes on the schedule. Better to be safe than sorry there.
I also use the trio. Use them together as they are designed.
I use full dose and just water between feeds. You might start with 1/2 if it makes you feel better. Your call there.
So I feed,water,feed,water,ect.
Here is schedule in case you dont have one.
The rule of thumb I use is use water half the gals of your pots.
A 5-gal grow bag requires no more than 2.5 gals on average to completely saturate
