Weird browning on leaves

So I got one purple punch and one lemon mimosa, growing in pro-mix, now the pro-mix is pretty old and I’m not sure if the lime in it has completely depleted cause my ph levels are 6.0 or below with run off. I can’t seem to stop these leaves from browning. I’ve tried everything. Flushing, feeding, lower power of lights. Has anyone seen this or know what could possibly be the problem? I know it’s probably too late to save them, but I’d like to know for future grows cause pro-mix is all I can afford at the moment. Please help.

What were you feeding them? They look like they've been overfed.

Lots of people use promix so if that's all you can afford that's fine. It's not the promix that caused that.

fox farm trio, I mostly use tiger bloom when it’s this late into flower. I just recently flushed both plants.

I was going off Ppm reading, around 700-1000 early flower, then I bumped it to around 1300 after I saw this thinking it was a deficiency, and then I flushed after it started getting worse. I usually half their feeding recommendations.

If you're feeding you're plants fox farm trio you should also use the grow big for the nitrogen but at half strength when in flower, looks like you over fed you're plant when you water do you get 10% run off? and are you letting you're clean water sit out for at least 24 hours so the chlorine evaporates? Also what is you're run off and you should be properly phing you're water at 6.5 if you're in soil

Pro mix likes runoff every time you feed.

Over watered, try watering with a bit less water or less frequent. I can see in picture 3 you have her setting in her run off. Normally burn edges and curling up which advance to rust spots looking like potassium deficiency is a sign of overwatered or root trouble.

Try only half of recomended dose of fox farm. Im using the same thing and ran into same problem. I cut the foxfarm dose to half of what the feeding chart says and no problems since.

I do have them elevated so it doesn’t sit in the run off. But yeah I’m hoping it’ll be okay. I’ll just try better next round
