Sweet Cherry Kush with a side of White Widow

Week 3 of flower is in the books. Defoliated and lollipopped them this week. Not sure if I overdid it (first time) but they seem to have bounced back alright. Middle plant and the white widow on the right has started to turn a bit pale, so I've upped feedings and added a bit more calmag and raised the light a bit. From what I've determined from online sources it looks mostly like a nitrogen deficiency but we'll see. Somewhat concerned over the leafs thinning out at the top but we'll see how it goes after upping nutrients, they don't look miserable (yet) hopefully some food will help.
