Looks like heat stress ,if your light has a dimmer try turning it down some. If no dimmer then raise the light if possible.

Spotted crisp leaves
What's up with these leaves? They've all been spotting up, crisp edges and tips curl. I keep flushing them and it helps. I feed them 1 tsp calmag to each gallon and often the mixture gets diluted as much as half. PH water was 6.2 but soil 4.5. 15" from 70% light.

Everything was fine til it wasnt. Came out one morning after several days of tough heat and wind to discover what I believe is budrot and some other disease I cant quite identify. I havent changed up my watering schedule aside from the occasional afternoon watering.
