plant problem, help please

hi, thanks for the help

I've scrog 6sour diesel, in a 25sq ft tent with a 1000w hps at 4feet from the canopy.
Temp goes from 27celsius (top of plant) daytime to 20celsius at night.
22days into flowering.
I'm using biocanna soil bio terra plus with bioflores 40ml/10l, bioboost 20ml/10l, enzyme 1g/40l, a product called Elemental (worm juice with vitamins fertilizer) 20ml/10l, and Nitrogen 2ml/10l.

I have searched and I can't pinpoint what's wrong with the leaves.

Can someone help me?

sorry for my grammar by the way.

Where did that leaf come from? Any tip burn at the tops?

the 6 plants have leaves like this one throughout the scrog. not at the top but like 3-4 inches under the top buds.

No burned tip. All the sick leaves look like the first pic.

Ok , not counting the leaves growing out of the buds (sugar leaf). Are those the highest fan leafs? Or there are other fan leafs up top that are perfectly healthy? Any heavy nitrogen deficiency down below? Looks to be Fe deficiency, the yellowing could be root issues , bugs or N deficiency. Keep in mind they could very well be lockouts too.

all fan leaves seem to be affected to a certain point, the highest are greener but clearly there is something going on with them too. a couple of leaves are dying(browning and drying) from the tips but its under the screen, so I guess that's normal.
i've had problems with watering the plants for the first 18days, couldn't let the water drain from the pots so i was watering every 2 days without flushing the soil at all, but i did watered only with water once every week, could that induce lockouts?

see, they all look sick

27C is pretty warm for an indoor grow. that's about 85F.
how about that soil? if it has fert in it already, you don't to add much, or at least until the plants start to show nute deficiency.

Check you're run-off ppm. I think you could have over-fed. If the pot had bad drainage it will stay wet longer, on top of you feeding it synthetic nutrients every 2 days could have also built up salt at the root zone. That will cause her to stop eating. If you have already flushed before this problem then she may be hungry. Checking ppm would be the best way,dont forget about pH too.

Nutrient overdose - Flush plant for 1 week - then re-adjust nutrients and feeding times (should feed plants 2 days out of 3) Also one should flush plant on a regular basis every 4 weeks to pre-vent plant problems.
