Light source CFL’s ? Heat issues ? if nutrient issues all leaves would present it - Nutrient splash ?
Are the leaves stems purple? most of the leaves look like contact burns from splash but some show signs of mag def.
What are you using for nutes? and are you adding a Cal-Mag supplement?
Magnesium def would most likely be your culprit since it is more readily absorbed in higher ph. Let your ph fluctuate between 5.5-6 if you add Cal-mag set ph 5.8-6 will absorb and clear up most of the issue though be easy on any feeding during root recovery think like its a fresh cutting. Carob molasses may also do the trick if you don’t have Cal-mag supplement

Keep in mind ph of 6 would speed ability to absorb but 5.8 will work too if you don’t want to risk overnight ph climb
Yes botanicare cal-mag
