I can't figure out this issue

hey guys my blueberry has been loosing its leaves from the bottom to the top for about a month now. They might have started as nite burn but now i believe it's not. But also idfk lol. It was experiencing these issues when I topped it so that didn't help. Also didn't get a ph kit till about two weeks ago and I flushed it with ph'd water around a week and a bit ago.

600w hps around 2ft away
Not the best drainage soil but the flush proved it's not horrid
Few other plants in the same tent had similar issues but recovered. Gave this plant the same treatment as them.(transplant etc)
Roughly 150-300ppm tap water


Was gunna let it go and focus on new growth but it's hit my last set of leaves where I topped. So getting worried
Help?

Your water is really hard I would try using bottled water which is depending is like 0-150 ppm's. Ph your water I'm sure that is some of the cause and you can probably move the lights a little closer I keep my 1000w around 2ft away, are you feeding them at all? What are the temps in the room?

ok thought i might have to get bottled water. I dont have a feeding or water schedule cuz each of my plants takes something a bit different. I flushed my plant 2 weeks ago with 6.5 ph'd water and 1/4 feed, haven't watered since. Haven't noticed signs of needing it and they were all pretty badly over watered. I'm using a 25-10-15 synthetic fert. I have an inline fan in my 4x4 tent and an open window with a fan slightly blowing in winter air to outside the tent. Temps go from 65-85 but average 75. Only hits the high and low if i didnt put my window fan on the right setting

That’s a wide temp range I’d try to close that gap a little if you can, and you seem to know your problem the overwatering. I’d flush see if it helps then start using bottled water. I don’t run a feeding schedule I just know how the pots feel when there full of water so when they feel light I water em.

Alright sounds good. been trying to reduce the flux but temps outside vary a lot lately and i dont want my roots or small plants to be too cold when my inline fan sucks air through slots on the bottom of the tent.

Yeah weather has been weird where I’m at also so I feel ya I just try to check the temps twice a day adjusting fans as necessary.

Oh also i flushed it 8 days ago and transplanted it a few days before that. Its doing a fair bit better but yeah.. So a few questions, Is another flush advised still? will Ph'd tap water that sat out for a few hours work for the flush? And i'm assuming no nutes? Or a low dossage?
