Help to fix my plant

Hello my friends. It's my first grow and already in week 3 of flower. My blueberry started to get yellow leaves on top. It's problem with nuts?

What are you running for lights and how close are they? Based on where the damage is, and how the rest of the plant looks healthy, this looks like light bleaching to me.

Actually, it's hard to tell because now I see some damage on the lower leaves. Let's start out with you telling us what you are growing in (Soil, coco, etc). How much, how often, and at what pH do you water? What are you feeding, how much, and how often?

Good call brotha! Even the bud looks like it got a little toasted. She will live, don't worry.

Sorry I forgot the details. I use the biobizz all mix and for nuts now in flower i use bio heaven, bio bloom from bio buzz and big bud, bud candy, rhino skin, carboload from AN. I also used fish mix for the first 2 weeks but now I stopped. Maybe the plant needs also some N? I run a 1000 watt CMH and 2x quantum boards 240 watt each for 4x5. I have raised them at 3 feet from the top. My temps also are 21-26° lights on and 17-20 lights off. Humitidy 30-45% max 50% lights off. For air ventilation 2 fans 1100 CMF each intake/outtake with filter. The temperature on tops doesn't surpass the 30° I have a fan blowing the space between tops and lights.

Also some bud pics.

That sounds like an awful lot of light for a 4x5 tent and those buds look light bleached to me. The two 240W QBs are pretty close to all the light you need for that footprint. Why did you add another 1,000W of CMH?

Cmh+qb spectrum gives very heavy buds

I also have this plant in flower room. It's a bit big. Almost 3 feet tall and 4x4 wide. Sweet valley kush. I think it will yield heavy

I get that, but you have more than double the power you need, and I'm pretty sure that is your issue unless the room is sealed with CO2 and environmental controls.

Classic Fe def.

Likely a blocking situation from something in your feed mix vs the soil you use.
It could also be from a slowly growing pH issue that was brought on by the above mentioned problem. Those things go hand in hand...

Cracking a plant with more light intensity then nature... Is never good....

"More" is not a good thing
