I would flush using the sledge hammer at a PH of 6.8-7.0 until your run off PH is in range

Solid choice, I would say.

Thanks, @OGIncognito and @Growdoc . Know sounds dum, only dumb question one not asked. So when check my run off do I check the sledgehammer returns or run water through after to catch readings, if ya know what I mean. I really appreciate all help, I’m get away from ff one day.

You can catch a sample from using the sledge hammer. Let a good amount of the run off go then take a sample. Depending on the size of your vessel it could take several gallons. Follow the flush once the PH is in range with a feeding of 800-900 PPMs

Thanks @Growdoc & @OGIncognito , yea hopefully she will be forgiving lol I probably really aggravated her poor girl. I gave her some grub it was around 950 ppm, and 8ph. I’m leave her be til she’s thirsty again day or so. Really appreciate all the help. I need to get away from ff I see lot people talking about jacks. And probably wouldn’t have so much trouble to if I’d use something along with ff happy frog think see some use pedilite or something lol have to look back. Just have so much ff nuits I like to use the
Up. Anyway thank y’all so much and I’ll keep posting, now time for some R&R with my new friend lobo man I luv this thing. Love how you can really taste the flavor of your weed. Again thanks I know I pestered yall but thanks and happy grow my friends.

As long as you have meters, you can get by fine. You can add the fancy stuff later if ya like. It don’t make it grow better, just more convenient for you on mixing and such. I do recommend an electric stirrer, they are about $20 and money well spent!

Not really just some light flushing until she gets back in range is about all I would do, maybe a ¼ strength feed or so once she is dialed back in to make sure my Ec was good.

Well good morning all my growmies. @OGIncognito, @Growdoc, @spankyjr1 So she’s looking better today I believe her numbers are a lot better. She’s was thirsty so I gave her a drink water and grabbed some ro.
How numbers look to y’all? I know ph little high. So on EC what are we looking for versus ppm. She’s about 4weeks young.
So my meter shows say 1100 but like y’all say 1.45 or on ff sheet it’s a number with decimal. Is there a factor to use to convert it. lol

According to your pictures of meter readings, PH is fine at 6.7
Your meter is showing 476 PPM (that’s low, should be around 1000PPM at this stage of growth) IMO
I would feed next time going in around 800PPM and no lower than 6.5PH
and your EC is .951
PPM is about 1/2 of EC
1.00 EC is about 500PPM, depending on what scale meter you use
