Three of my eight plants have some of these BIG brown area/spots on some of the leaves. So my question is what do I do to help stop the issue. Here are the specs on my grow.

1) Using Miracle Grow ??mix? (not soil). Yes its mix and not soil, I just realize my screw up but in this deep 8 weeks and can not turn back.
2) About 3 weeks ago used MG (diluted) liquid fertilizer. Most of my plant tips are brown so I must have not diluted enough
3) About 2 weeks ago change my lighting to three 90W LED UFO lights one 126W LED
4) About 2 weeks ago transplanted to bigger pots
5) Temp is 75 to 80 degrees



How do I stop big brown area on leaves?
Did I really screw up by using MG potting ??mix? and not ??soil??
Shock from new lights?
Shock from transplanting?
All of the above?

Thanks for any ideas/input
