Leaf burn, spraying with lights on

To help it would be beneficial to see a pic of the plant, please no blurple pics since we can’t tell the true colors in blue red purple or yellow light.
Its not a good idea to foliar spray chicks during flower, you can set yourself up for pm or bud rot and both are bad news. But I suspect the plant is experiencing regular senescence. Is it a photoperiod an auto or from bagseed?

The leaves on a flowering plant turning yellow in the last several weeks is a very, very common thing.
Mild cases of yellow leaves is nothing more than the plant using the nutrients that were stored in the leaf and now it is shutting down the life process in each leaf as it finishes.
Providing the right fertilizers earlier in the plant's life will slow down or eliminate the yellowing of the leaves because the necessary nutrients are in the soil in large enough amounts that the plant does not need to pull them from the leaves.
They will not recover. The plant is finished with those leaves. If the plant were to grow new leaves then those would be green but the old ones will stay yellow, or maybe turn brown.
Please provide a photograph of the whole plant just to be sure that it is the usual sort of yellow leaves and not another problem. Turn off any grow lights and use just normal white room lights so we can see the true color of the leaves.

That’s not senescence - we need more info. What kind of soil? What brand of nutes? Do you have a cal-mag product? Are you adjusting ph? To what value? Can you tell us more about the steps you use for mixing your soup?

No worries - pests happen. I tried to nail my ipm routine long before flower cycle begins but one way or another I’m the king of bringing nasties into the garden. Maybe nutrient deficiency, I’ve got to roll out the door but drop some answers from questions on post #6 above and this crew will get you sorted

Ah well, there you have it! Ok that’s just light burn or bleaching thru the spray. Water & oil droplets magnify the light and cause slight burn to leaf surface. Those will not recover the green coloring but should be fine. Turn light off or remove from tent to spray in future, gentle fan to dry leaves before putting back under lights. You appear to be in great shape no worries just slight damage - Gonna roll now but will check back later.
Hi Z0nnk - try to spray the undersides of the leaves where the bugs live - can't think of any that live on top so no point spraying there plus you run the risk of bud rot if you're not careful
Those leaves are dark green, really dark green. Plus the spots are not yellow, they look almost burned white, as if the spray was to strong and not because of any lights.

Do you think will affect the buds?
No, but the dark green color and the spots could indicate something that might have an effect on the overall health of the plant when it flowers.
