leaves light green

Leaves "turning out in a very light green and feeling really soft" might be due to root damage. Leaves don't look droopy, I will make an educated guess that it's not overwatering. Maybe you damaged roots during LST? Brackets you use look heavy.

Looks at the plants in sunlight or white light, the light from grow lights tents to be quite warm and may downplay how green the plants really are. I agree that they look like they have a bit of burn on the tips. nothing major just back off the feeds a bit and follow their guidelines. Also be sure to get some run off if your in soil less media and if your in soil you feed them less, like once a week and the rest of the time just water. Good Luck!

I do not see signs of under feeding here. What I see is a slight nutrient burn on the tips caused by too much fertilizer and/or you letting your medium dry out too much. I would just follow your nutrient manufacture recommended dose and not change anything. Make sure when you water that you get roughly 10-20% run off out the bottom. This will avoide nutrient build up in the medium. Hope this helps

The green of your girls are perfectly normal, instead be aware of overfeeding, as I see a start of burn on teh tips... Have a good grow !
