Leaf tips yellowing again

So my gg4 plants have been kicking my ass I wasn’t giving any nutes for about 2 months because I was using soul that feed for 30 days first 30 when the plants were you g everything was good I repotted them in 10 gallons fabripots with the same type of soil thinking it woulyfeed them another 30 days and give them straight ro water with cal mag I was wrong the plant were getting real light green and the tips of the leafs we’re starting to yellow Iit probably didn’t help my ph meter was off I was giving the around 9 + ph well I fixed that problem started feeding them nutes first 500 ppm then 800ppm 2 to 3 more watering the plants looked to be getting some green back then now recently they look like they are falling back in the same shit I think I may be over watering idk maybe a flush now but should I flush if I’ve been over watering

Pics?

What’s the brand of soil you are using?

Roots organic 707

I am only having problems with the older plants on the right and they are in the roots organic 707 the younger ones on the left are just in pro mix and having no problems

I don’t know I’m not familiar with the new nutes I’m using and not familiar with using the fabric pots or having a 10 gallon medium any suggestions on how much water to give them

Seems like good stuff looks like I shouldn’t need any cal mag I wouldn’t think

Does the bag say what the NPK ratios are?

I don’t see nothing I did do some research and found it is safe for younger plants and they do great I know it’s not as hot as foxfarm ocean forest

And I do think it holds moisture longer wich could also be my problem

Your new growth looks ok... it's just the older leaves that are damaged by your ph fluctuations.

Get your ph sorted and feed them at a low level 700ppm should be fine...alternate water and feed daily. Just keep ph stable.

Once you see all new growth is fine remove all the yellowish leaves to encourage the new greener leaves to grow and you'll be fine

So you’re saying water with Nutrients daily but lightly

I see every other watering use nutes

Without knowing the NPK ratios of your soil, if there is in fact any in there, adding more nutrients is a recipe for disaster if it’s not needed, because the soil contains all the nutrients you need. You just water and that’s it. I use roots organic terp teas and both bags have the NPK ratios notated at the top of the bag, but they are amendments not soil. I would reconsider bottle feeding until you know for a fact that the soil doesn’t contain any.

I know it dose contain food I just think it’s on the lighter side and definitely out by now

N-p-k is 5-3-3 of the 707 soil I found it on line in a thread

Anymore more input

Think I’m going to give them strait water with this 5 benefits in one
