Leaves yellowing during flowering?

I'll take a few pics out of the tent, how/where should I attach the images? Also thank you for the help guys, still trying figure things out ahaha

I wonder what @Fruitgrower would make of this?

Wouldn’t a magnesium deficiency cause noticeable yellowing between the veins? Or light green edges? I’m sticking to my answer. Give us a picture with good lighting.

Бро, приветствую тебя! 👋 У меня были такие же лампы и я понимаю что это дефицит магния, если дело идёт к урожаю, то это нормально. 👍 Рекомендую снижать концентрацию магния в поливе с середины цветения и исключить магний на стадии ripening. 👌😇👍 Удачи, бро! 👋

Can I get an amen!

I would give it a quick flush or straight watering then resume feeding at reduced strength

I fail to see how this looks like a Magnesium deficiency at all. Nitrogen deficiency makes more sense but even then these leaves are not yellowing uniformly and to me plant looks really dark and shiny with leaf tips pointing downwards. When a plant is Nitrogen toxic as this appears to be, the older leaves will yellow from the tips inward while the rest of the leaf looks green. Dial back on nutrients especially Nitrogen. Please take your plant into natural light for proper colour rendering and diagnosis in the future

the distinct bottom-up is another indicator of N-def

from tip in, advnaced so you have dead spots at end... look more like nitrogen deficiency. It's a bigger plant and needs more fertilizer per week than before.

Look like a magnesium deficiency. The edges of the leaves may become yellow or bright green and may start feeling crispy to the touch. This crispiness around the edges is different from nutrient burn, which does not lighten the margins inside the leaves.
