Ran my temps a little too high the other day and now my bottom leaves have this discoloration. Should I remove the bad leaves or just leave them?

I'm growing an indica bagseed in foxfarm soil with foxfarm trio of nutes. My first grow. In a closet with a 60w led panel that's supposed to be equal to 400-600w hps. 1 gallon pots. Some bottom leaves are turning yellow, which could be nitrogen deficit or from not getting any light. Some of the higher fan leaves are getting dark spots then wilting and dying. I thought it was nutrient burn at first so I flushed the soil with plain water the last two waterings, but now it's showing signs of over watering. Can you guys make any recommendations as to what's wrong, besides over watering? Any tips to maximize yield? I'm 2 weeks into flowering, problems started when I started using the big bloom and tiger bloom fertilizer, which is what led me to think it was nutrient burn. Should I just pick off all those dying little leaves at the bottom? Thanks This is the worst looking of my 5 plants

Just wanted some opinions/advice on whether to transplant into a bigger pot while it's in flower stage. I'm not a grower just an experimentalist naturally.
