Nitrogen or Potassium deficiency?

@nobodysbuds, I relocated the plant into a bigger reservoir (3.5 gal) added water and PH'd it. ph is at 5.87 and ppm/ec is at 176/354 when I added the new water mixed with the older water that had nutes (did a water change same day as my other grow). Should I leave it as is for a week and see what it'll do? Or add more nutes since the ppm is pretty low a 176 during week 4/5 (this plant was originally planted on Oct 4th) I just don't want to give up on it lol

nute burn

Ppm is at 671. This grow was originally my first grow. Then I scrapped it and turned it into a kratky setup and see what I can do, instead of throwing it away. I started another grow already, not sure if you guys checked it. Maybe that’s where you’re referring the silica.

I’m testing ph. Ph is fine at 5.8

Are you testing ph? I saw you are giving a silica supplement and that can rise ph a lot. I know you are using “ph perfect” products but that’s just a claim.. You should start over with a new growth, plants suffering so early in veg are going to be weak. Go easy with nutes and supplements during the first weeks!

Not nitrogen deficiency as it looks to progress interveinal and the tip burning early in process. Calculate your ppms from guarnateed analysis labels. Ensure you aren't locking things out. check pH etc etc... if you start to see the darker spots along with interveinal chlorosis, it could be K-def. I'm leaning lockout because it looks like a mix of symptoms.. trace elements being locked out like Fe or Zn. That'd be really unlikely for any blend of hydro nutes not to include those at a proper concentration. pH is another big factor here.
