I realized that the lights were too close to her.. she had grown a lot in 2 days..
Can this be due to heat? or is it something else?

Can these leaves be recovered? Humidity is not a problem. It can either be heat or some nutes messing up.. PH of soil is 6.8. RH is 59%
Temp at base of pots is 27 deg C. I am using CFLs and lamps are 2 inch above top of plant. This happened only to the top... so it seems to be the heat.

The top of the leafs are already dead. You can chop these tops off.
