One finger leaves

Looks like light burn to me- the lower leaves look good.
You may need to dim your light source a little bit.
You can up your current nutes a bit- they are always hungry during flower.

It is only effecting the parts near the light so I’m very unsure here haha

They’re under 600w HPs the lower stuff does seem ok it’s more the light centre

Looks like a Ca deficit and bad enough if you look at pic #2 in the upper right unless that's a lighting artifact it looks like you may have some PM in the damaged leaves. Take a really good look for that.

Honestly if my plants were pitching such a fit and they were in simple plastic nursery pots with coco/leica, and you're doing standard drain to waste system I'd drop the additional Ca and lower their nutrients to say 650. I'd also remove the heavily damaged leaves so you can see if you're improving.

But like I was saying there are a ton of more experienced growers here so let's see what they say.

I agree with curious- all those damaged leaves need to go ASAP.

I second cut back on nutes, I wonder if its too much k causing lockout (too much k can lockout cal, mag, iron, zinc)

how much were you feeding?

 

[Dazza1529]

I’m feeding 1.4ec using just A&B and add 5ml cal mag the overall EC is 1.4 the strain is BLUEBERRY OG

I third cutting back on the nutes, pull off damaged leaves, and dim the light slightly, not much. Also I never saw how often or how much you are watering. I would try dropping your ec to 500 and water once to a good runoff and make sure you don’t have salt build up, but knowing watering frequency and amount of runoff each time would help.

I’m in coco so water twice a day with a good 100ml run off both times

Whats your water source? Are you starting from an ec of 0?

 

[Dazza1529]

I’m unsure if my water starts at 0 EC but it dosnt show up on my blue lab truncheon before feed but they start at like 0.2 EC

100ml is not much as far as run off. I would still feed with 1/4 strength or so feed to a liter run off, then feed at only 1/2 strength from there and see how it goes. I don’t think it could hurt anything, and may fix the problem.

Hi guys so the dead stuff is gone EC reduced and to more run off the problem dosnt seem to be getting worse iv took some bud pics any idea how long they may take as far as iv been told they’re blueberry OG and the flowering time is around 55 days these are 27 days into flower
