Run off ph and ppm

[MrNoobman]

Growing autoflowers. 3rd week of flower.

Currently waiting on a medium ph tester and an ec pen.

Wondering if anyone has info on how low the ph of the run off should be roughly in comparison to when it's fed.

I'm feeding at 5.9-6.1 growing in coco.

Ppm around 650-750

Ph of run off is around 5.2 and one even goes to as low as 4.9.

Should I flush and feed at a lower dose or just wait for the equipment to be able to get accurate readings.

Sorry if this sounds stupid but I'm kinda new lol


Thanks advance

Honestly, I've stopped watching my runoff entirely. You just end up overthinking things and chasing the pH and PPMs. That said, runoff will typically be lower pH than the input, so that's pretty normal imo. You're better off just focusing on watching what you put into the medium and learning to watch the plant itself for what it wants.
Nothing looks obviously out of whack so don't flush, if anything perhaps lower the PPM of your fert a little to be safe. Looks pretty good otherwise!

Don't do anything except increase the amount of fert solution you're pouring to it. Or water it more times a day.

After a couple of days. Check it again. From all over the bottom of the pot. Not just one drip. You want overall, all areas.

Sounds good. Thanks a lot.
Another somewhat daft question but, for my ppm because it comes out the tap at 250ppm should I add whats recommended onto it. So if I want a 700ppm would I make it 950 or would I just make that up to 700.

Thanks dude

Good question actually, unfortunately not something I have personal experience with. I suggest you try to get ahold of your local water report and see if you can figure out exactly what's in your water. 250ppm is slightly hard, but not the worst either. It may be you have a good amount of calcium in the water and you just dont need to add as much CalMag to your nute mix as someone like myself who has very very soft water amd can feed a lower strength mix. Or it might be other stuff in the water that doesn't affect the plant as much and you could feed full strength no problem. I would start with a lower overall PPM to start with, see how the plant handles it, then gradually increase the feed strength.

@hotrodharley if you think your making a point its a bad one. Go look at the other top problem posts right now. Hydro and soil and soil and hydro....and this guy said he's a newbe looking for help, exactly the sort of person I said runs into trouble with coco. So thanks for proving my point. Now if you don't mind I'm just trying to help some people here because I went through the same learning curve.

I think you have helped me on like 3 separate issues now. Thanks a lot dude and ill get onto finding out what's in my water asap

Sorry, didnt mean to hijack your thread. Good luck!
