Help please not sure if these seedlings are nute def. or have lock out

I sprouted some seeds and they’re about 2-3 weeks old. I put them from rock wool cubes to 70% coco 30% perlite (royal gold coco). I never have flushed my coco before putting clones in, but I don’t have to much experience with seedlings and coco and noticed the run off was around 1800 and I have been feeding them tap water that’s 280 ppm .5 scale phd to 6.0. Some shriveled up and others are looking nitrogen Defeciant. Should I be worrying about the run off or do they need food? I also have been treating them for spider mites, could they be why some of them shriveled up?

If its 1800 in your runoff.
Its 1800 in your media.
You should be 2 or 300.
I reckon you have 1600 worth of salt.
Sorry man

Looks like you might have thrips or spider mites.

Appreciate the response. Would I just keep flushing till the run offs around 300 or get new brand of medium?

I’ll look into thrips, but I know i definitely have spider mites! I just defoliate everything and dipped every last plant in acid last night. Going to wait a week and hit them with need and azamax every other day for a week and I’m between set off 3 pytherium bomb 3 days apart, then 1 more floramite spray down.

They are seedlings.

If you have mites where did they come from? You need to do more than just treat those plants. The relentless, pesky fuckers can be everywhere in your grow space and beyond.

Yeah id be flushing it, with very light feeds. Working about 30% runoff.
Nice and slow. Every couple days.
Good luck

Well those are seedlings, but I have plants in all sorts of stages from flowers to clones and all in between. Hard to say exactly where they came from, but I haven’t done one lick of maintenance in that department i got way to complacent after my last slip up with them. I’m waiting on my last run of flowers to finish next week to rip everything else out and clean, clean, and clean some more and bomb the room several times. I know how bad those fuckers can be. I’m going full on nuclear on they’re asses and starting a routine to keep them out hopefully. I have dipped them and every plant I have not flowering in avid and plan on doing it again in 2 weeks.

I would try to get the runoff ppm down when you flush too.
Even if you do 2 flushes, in the day.
It'll rise again by next flush.
Important to get the runoff to read the same.
Good luck dude, you're no newbie anyway.
You'll be sweet mate.

Thanks amigo! Got the run off real close to my input! Just got my ro unit in! Going to start feeding them lightly and working it up. Always appreciate the input!
