Thanks, might’ve saved me a trip to the hydro shop! I’ve got a big bag my wife uses for the bath. This do the job (magnesium sulphate heptahydrate)?

just make sure it doesn't have anything like lavender or any other crap like that. just plain old epsom salts.

and as a FYI since we're on the topic, if you need to fix a Mg issue really fast, foliar spray with about 1 TBSP per gallon right before lights go off. (don't do this when you have flowers or you risk mold).

Thanks man, will see how it goes next few days. Pushed my EC up 0.1 and PH down 0.1 so I gave it a bit of fresh water to mellow out back to what it was (1.4 EC 5.5 PH)

They've recovered decently and even took a topping in their stride (3 weeks from seed). Wasn't sure they'd make it they looked so terrible when the Ph swings were going on View attachment 5192828

Yep all the way to the bottom. Water was just below the net pot. The drain is basically in the net pot centre with this system

Not really, it’s only a few handfuls. These get moved between rooms for different stages so need a decent stable base for the plants once they grow in.

They are 6” net pots like this
