Burnt tips diagnosis how to fix?

Hey guys supposedly have a Gary Payton plant here and we’re getting somewhat close to flowering being done but I’m seeing some tips that are burning in some sort or the other. This just started a week ago but now it’s affecting lower leaves too. I did accidentally let her go a couple days with needing water got pretty busy with other stuff, she made me sad but I quickly corrected. Buddy said it was an over feeding but would love a second opinion!

Fox farms ocean forest - Previously used for other grows so not fresh

Roots organic - organic powder nutrients

Led light - not sure on the watts but it’s doing the job for this girl

Grow phase - Flowering

Grow type - Indoor

Feeding schedule - last feed was 1 1

Water - as seen needed. No PH just let the water sit. Our Water isn’t thatfar off what she needs.

Looks like early phosphorus deficiency.

The PDF in the first post of the following thread has some real info in it.

Don't know about the second picture but the other one's look like to much nutes and therefore start burning.
How long do they have to go? What's you're current EC and PH? Could perhaps be a build up do to a wrong PH level.

Not familiar with the EC but I can check on the ph tomorrow when lights kick on.

Looks overfed...

Definitely check on that. "most" nutrient problems start by having the wrong PH levels.

Appears to have too much N and not enough P K.Could be the dry fertilizer has wrong ratios?. Perhaps root bound.Doesnt really look that bad.The purplish leaves as said above would be lack of P I think.
