Mmmh so
I see leaves with tip curling down and that would tell me too much nitrogen.
Then I see yellow leaves at the bottom like there is not enough nutrients.
I had this happen last year outdoor.
Contradictory...
I think your pH is off!
It went on nitrogen toxicity (curled tip) then lock out.
Yellowing from bottom.
At least,it was my problem.
My pH pen was broken.
When I could finally check my pH was at 8+
Corrected it and plants when back to full health.
Hope it helps
