Leaves Curling Up, Dry and Get Orange. Please Help!!!

Transplanted today into a 2 Gal container. At first plant had features of a high PH level,new growth was light green and leaves were getting smaller so I Lowered the PH with Fresh Lemon Juice and Water to Dilute it. Then tested soil and it seemed to lower the PH too much so I added some baking soda today with lots of water to raise PH and after that i decided to transplant plant into a bigger container than originally was. Now it looks like its drying. Leaves curling up alot and like drying out, getting crusty. Leaves are getting dark dark green with rust orange on it. I also gave a little nutes to the plant yesterday but i flushed it today. I am hoping the plant is stressing due to overwatering. Please Help!! Ill attached Photos, i can take more pics if requested. Also it was outside today in CA 60 degree weather while transplanting and flushing, idk if the sun might of hurt it. thanks

What are your temps mate? Looks like you had some heat stress initially.

too much water and your rh is probably off, lights are burning your plants, the curling tip means too much water

Dry them out and water 1- 3 times a week depending on plant after normal growth appears start nutes. Again also that's a big pot u should only need to water once a week check p.h and e.c
