Leaves dry and fall off in the middle of the bush, mites???

Leaves what are located in the shadow, in the heart of the plant or in the corner of tent are slowly getting brown and fall off. Dunno what it could be? Any ideas guys?
Coco coir, full series of Cyco nutrients, PH 5.8, ppm 1000, run off same

I had the same thing happen looks like light burn for the outer leaves and the ones on the inside I think she's just not getting enough light I would pick it clean ( the one that are all shriveled ) I turned out a massive plant in the end good luck

IMO: Serious nute issues

flush with 3 times the pot volume with air temp ph'ed water

no nutes for 2-3 weeks

later feed 50% less for the rest of the grow

check your temps install a small cheap fan

will mean you get some in for all your hard work

good luck

also check closely for bugs, my problem was thrips. what a pain in the ass they are. destroyed my crop

Forgot to mention, girls are in flower 2 week...
no nutes for 2-3 weeks seems to be little ruff?
I feed them with 1/2 nutes anyway...

Could it be because of light, because girls are REALLY massive (15-25 main tops, and 20-30 side tops)... So the middle leaves are almost in total darkness, and I am too scared to defoliate any upper leaves cos girls have been through too much of trouble...

Been trying to find any pest signs, none have seen, have read that Broad Mites and Russet Mites like shadows, so could it be them?

Cool! ...see you next week

get your scope out check leaves and buds

Yikes! I've been growing in coco for years and have never seen anything like that.

That coco looks pretty wet. Are you letting it sit in the runoff? If so you shouldn't.

When was the last time you calibrated your PH pen or at least checked it with PH solution?

Are you checking the PH after you mix the nutes or just adding nutes to PH'd water?

If you're two weeks into flower you should be seeing pistils. I don't see any from those pictures.

Are you sure your timers set for 12/12?

You're using the full line of Cyco nutrients? Their feeding chart has at least thirteen different products. It would be easy to get the measurements wrong with all that stuff. Especially the silica they have you feeding in flower. I don't understand why. I don't use it but I thought most people used it during veg and stopped during flower. The one time I used silica in veg I used too much and I remember now that I had leaves dying on the plant. I haven't used it since.

That's some serious die off. If you don't already have something else in the pipeline I'd get on it immediately. The yield on those is going to suffer significantly. I'd almost think about switching back to veg schedule until you can get the issues resolved and the plants are healthy. Sick plants don't flower well.

Good luck.
