looks like a heat issue to me....when you say 21", are you saying inches or centimeters

your temps are a bit high but not outrageous

Hi.....its inches

28 to 30 celsius is too high and pH of 6.3 is too low for soil. You should have your pH around 6.7 when you water but I think the bigger issue here is heat and lack of air movent...get a fan. Make sure you have lots of air circulation between the tops and the light and find a way to keep temps between 20C and 25C.
BTW if your humidity is below 40%, 30 degrees is really high!
