I've had this before, mine was due to calcium/magnesium deficiency, are you using calmag as part of your feed?

What do you guys think is wrong with my leaves? I think it's lightburn because it seems especially bad and concentrated directly under the grow light but then again I see some off these spots far away from the light so I'm unsure. Over-fertilization maybe? Mostly on canopy level

First grow with autos, are these growing too slowly after a week?
It's the start of day 7 and compared to some other posts, I worry these may be smaller than what they should be after a week. Are growing slower than they should be, and is the discoloration on the 2nd image a cause for concern?

In picture 3 above the new growth on the main cola sites is curled up and contorted. pH is a tiny bit high, TDs run off is around the 400-600 mark over the week. Humidity has been intense for weeks in the high 70s to mid 80s, I'm only watering to feed once a week. Help!

The tips of the upper leaves (as shown in Picture D34 - Top Flower) are turning slightly yellow. Since the plant is in 2nd week of flowering, should I be worried or is it normal?
