Is the idea to try and keep the PPM going in the same as the runoff? Week 2 of flower and I’m feeding 1500-1800 PPM. My runoff is 2-3 times that. Should I use pH’d CalMag water until the runoff comes back down? Using Fox Farm “trio” nutrients.
Yes, you’re going to want to let that come down. If it doesn’t naturally, a flush will be needed.
@BobbyDigital Is a flush 2-3 times the normal amount of water I would give her letting it just runoff?
If using sledgehammer, then yes. If just using plain water you’re looking at around 3x the amount of your pot size. So if you’re in 5 gallon pots you’ll need around 15 gallons of water
What kind of soil are you using, and did you transplant into new soil just before flower? I ask because I know with the soil I use the runoff PPM’s are ridiculously high for the first several weeks of use. This can trick you into thinking there’s a problem. The organic materials in the soil are breaking down, as they should be, and this shows up in your PPM reading.
@Cap_Ron I’m using an organic soil from Lowe’s. It started out as an experiment seeing if I could get a plant started and turned into a full blown female plant that is doing great.
She looks great. I don’t think I would flush that plant based only on runoff numbers. If anything, slightly reduce your input PPM and see how it goes.
What is the pH of the runoff? When I used soil I ended up paying more attention to pH than ppm. If the pH drops a bunch over time, something like .5 or slightly more, I new salt is building up and need to correct it. With FF trio having to flush is part of the program. At times I would do a mini flush when I see ph consistently dropping with ppm increasing.
I would decrease nutrients and increase the amount of solution in order to have 25% or more runoff. This is just informational at this time.
Looking at your plant I don’t see anything that would cause alarm. However, if ppm don’t start decreasing and ph keeps going down, then some action is called for.
@beardless pH going in 6.4-6.8. The runoff has varied from the start with pH between 5.4-6.1.
Try plain tap water without pH’ing it. That’s the only way for my runoff to come out at 6.4 consistently. When I use pH down my soil started to slowly (see below)
Plant looks great ! I’m with @Cap_Ron I Don’t think I would flush plants happy. Go with PH watering till PPM drops to feeding range.
