Flushing in coco, help

hey all,

I’m coming up on 7 days of flushing at 250ppm cal mag and carboload.

I’m getting solid run off while putting 10 gallons of water through the coco for feedings ( Once a day when lights come on)

With run off testing first at 750 now recently at 300 with a ph of 6.1 I’m curious if I can flush once more tomorrow evening and cut down Saturday.

That’s of course assuming my run off is 250 ( flushed of previous nutes and reflecting what I’m putting into the medium currently )

Let me know if I’m headed down the right track.

Thanks in advance!

Happy growing

The prove will be in the pudding

Why are you using cal-mag during the flush? It's got Nitrogen, which is what you're aiming to leech out of the roots during a flush.

I was told never feed with plain water while in coco which would lead to never feeding the plant for 7-10 days

if you are doing a flush to stop nute burn or lockout, then you flush coco with light nutes.

if you are doing a pre harvest flush , plain water is fine.

Or RO water is what i use.

Water with Pond zyme or a different Enzyme to break down dead roots is a bonus to the plant during the last couple weeks.

Thanks for all the replies you are all awesome, here’s a macro shot of my two flavors I ran. Waiting to chop down after New Years

That's a cool rig to check out trichs - they're looking perfect too. Nice job man

Yeah I would think the whole point of a flush is to remove any chemicals from the weed. I suppose if you feel your dope doesn't stink enough you could add sweeteners but it's not my bag.
