Flush feeding

[Dr. Monty]

When dealing with nute lock or burn do you flush then feed a little or do a flush with the food already in there?

using promix, 15 gal smart pot, Heavy 16 nutes, LED lights

all different plants

What ppm were you feeding?

 

[Dr. Monty]

What ppm were you feeding?

I guess heavy 16 goes by ml instead of ppm but I used about 1/3 strength and my ppm was around 800.
I never fed enough to where it was coming out of the bottom of the pot very much tho

Woudnt hurt to flush. Id go 1/2 of that.

Check your runoff ppm while your at it.

Check your runoff ppm while your at it.

What ppm should I have on a normal day? Lol I usually don’t check it lol

Some run pretty high 1000. I tend to error on the low side. 500-600 in flower. My theory is if your runoff is real hi your plant is not using the nutes. Cut back. Oh thats with ro. So just nute ppm. Some feed high and water with runoff to keep from building up, but i believe its a waste of nutes. I know in coco you can shoot for 300ppm over what you are feeding, not sure about promix. May be the same. Iv had runoff as hi as 2000 and the plant looked a fine a little burn on the edge but i was shocked that it wasnt burnt bad.

Your plants dont look stressed so id flush and go back to what you were feeding. Cut some if yojr runoff is high.
