Could someone help me with idea what nutrient decifiencies I'm having?

Please look at the following images and corresponding numbers and either vote or comment with the number and nutrient deficiencies or problems you think you could help me with. I am currently using a 400 watt light moving up to 1000k watt in a few days. I use Fox Farm grow big hydro 3-2-6 in coco perlite 50/50 mix. Plastic 3 gallon grow bags.

You shouldn't have a deficiency with that setup.
Are you using CalMag?
Are all the plants in the light's footprint?
Also, soil looks wet.
Whats your water cycle?

Those look hungry to me.

more food(nitrigen-potassium ) and less watering(let the soil/medium dry up a tad) fungus gnats will probably be an issue and root problems if you keep it wet all the time .. increase your air movement , this will help in drying the soil some.

First off, thank you for the comments. I'm feeding 2 teaspoons fox farm grow big hydro once a week. 36 hours ago was first full strength feeding. I water once every other day. I've got a fan running on medium (not pictured). Definitely going to be getting some added calmag, which I could probably add like 1-2 teaspoons every feeding. Seeds are seedsman white widow, blueberry, jack herrer, and Neville haze.

You're growing in coco. You feed every watering.

You're starving your plants - that's the reason they look bad. Coco should be fed daily and always to 20% run off - never just water or you'll mess up the CEC. If you treat it like soil like some of the above posters suggest you will have problems. Coco is hydroponics - not soil. Good luck.

two more cents,, next time use air pots or fabric pots with coco..
