First time grow all alone and can not figure out my problem 100%

[The420Grinch92]

UPDATE -
I am shocked at how my garden is doing for my first time. Honestly i didnt think i would be getting the results that i am. Im on week 5 of flower starting week 6 and i believe its time for me to flush them. I have been reading and trying to learn everything i can to keep a healthy garden and have a great outcome. I would love to hear ideas or feed back on ways i can improve my garden. I am going to start flushing them all now since they look like they might have a little extra nutrients in them. Maybe i should have already started to flush but we learn as we go. Also im noticing the pistols are starting to brown but very little right now. Any suggestions are always appreciated and added to my growing book for me. Each plant is different which wasnt the smartest start.lol

Sour Mango sherbet

Sour Mango Sherbet with chemical burn i believe because some very low branches are starting this also.

whole garden. I have been defoiliating as i go so light isnt blocking mainbuds.

Do you have a red and blue switch? If so you prob want them both on.

I have had them both on for a while now. I believe during week 6 of flower they are starting to get light burn. Should i turn the veg off and just have bloom on or will that mess with them?
