Doing this on a phone?
I have no clue,what next to do.

It's formatted for a computer.

With the information you just offered, I'll hazard a guess.
That looks like an over-nute problem and shows signs of several deficiencies.
It can actually be both, if the PH is out of range.

That said, I would start with a good flushing.
Run PH adjusted water through the soil to rinse it.

Then, when dried a bit, mix your nutes, let the water sit for an hour, then shake some air into it and measure the PH.

Water the plant until there is just a little runoff.
Catch the runoff and let it settle.
Then check it's PH.

Post your findings and we'll figure out a fix.
