Medium/grow method: ffof w 30% perlite

Feed: and supplements used:1 feeding of megacrop and sweet candy @half strength

water source:tap ph to 6.5

Strain/age: blue mystic 26d

light used: an 288 @ 100 watts roughly 22 "

Climate:78-81f 30-40 humidity (stealth gun cabinet grow)

Additional info:first grow. I had major heat problems and overwatering issues to start out . I seemed to have everything dialed in and getting good growth every day. What do these leaves indicate? There are a few more of these in back but most of the plant looks great. Thank you for you help!

I see that you are using tap water, make sure to let it sit open up to 48 hours to let Chlorine evaporate. I would also add some calmag to your feedings. Another good place to start would be to check the Ph of your run off water and the ph of your soil, you would need a soil ph tester for that tho.

Looks like some nutes got on some leaves.I would recommend removing those bottom leaves that might be touching the soil or the ones that are not getting any light.
