Ok thanks I was currently trying to flush and star...

Hi there Tangie, you're starting to do the right thing, but it takes a bit of time for the "inertia" to reverse, meaning it will take a week or ten days for the serious problem to stop spreading and reverse. There's a pretty huge problem with the "pH-perfect" line of nutrients called "it's not perfect pH at all", meaning it's causing all sorts of problems. your main problems are potassium issues, that you can see from the coloful discoloration; and a magnesium related issue , this you can see from the discoloration of the serrated edges of the leafs. You can tell it's from too many nutrients from the burnt tips. If you take a look at the ingredients of what's inside what you're giving them you'll see you're giving two NPKs and two Micro nutrients, you should be giving one NPK, one Micro and one additive. So to fix this you want to find and add a humic acid, this will stabilise your pH, remove excess nutrients in your soil and help with getting the nutrients to your plants. Do this and the problem should stabilize within ten days or so. Hope this helps growmie ! 🚀
