was going to say what Joomby and Nug said. are your plants still transplantable or too far along? theres a few things you can do to bring soil pH down quickly but it comes with risk i.e. you can go too far and/or depending on whats in your soil it might buffer what you throw at it so the balance will be all screwy. theres longer term (and safer) measures but by the time they're working your plants may well be fucked. Not something I've faced myself so I won't offer advice as such BUT if it were me (and it were possible to do so) I'd get them the fuck out of that soil and into something else pronto

Dolomite lime is one such soil additive but it needs to be mixed in so a re pot would be nescacary.

My plants have been in their new pots for a couple weeks so might still be able to dig them up. The newer leaves seem to be looking fine however so im not sure if leaving them would be the best option or not

Dolomite lime is a PH buffer. I thought it gave u a PH of 7 but after a quick read I may be wrong.

yeah its definitely a buffer so would have a neutralising effect of sorts but its better for raising rather than lowering - it will also effect your ratios of Ca and Mg - possibly in a bad way.

@C00pers you can also look into a few acidic organic amendments as a top dress like peat moss amongst others but take that with a grain of salt - I've never had to drop soil pH to the extent you need to and I'm just not sure how quickly this would work for you. the growers bible has a big section on acidic and alkaline amendments and their effectiveness but I cant for the life of me find it in PDF - I have it somewhere just cant find the fucker

Ask @OzCocoLoco when hes about. he is quite the soil nut. I hope you see a bit of improvement with the change to your feeding in the meantime

Yeah cheers will do im hoping the plants can get through it or maybe the soil might stabilise since its a new soil

Those soil test kits are a bit funny depending on your sample size,you have to take samples from as many different parts of the pot as you can mix that all up then do 3 or 4 tests and get an average. I’ve only tested native soils though ive never phed my container soils but that test is really out I’d be doing a few to see if you just picked up on a pocket of something
