What are you feeding them? How much? How often? Average greenhouse temp during the day? Are you spraying anything? And if so what time of day?

 

[randomuser420]

The whole lot of Biodiversity products. 1.5 times a week. 85 degrees. Spraying for bugs but generally only every 10 days and always after 6pm. Definitely not spray burn. It'd be spottier. This is def a nutri burn or deficiency.

Its nute burn. ok. Is it getting worse?
Whats your nute recipe? Do u water with plain water before u feed them?

I'd say it's slowly getting worse, yes.

Nute recipe: http://www.gobiodiversity.com/documents/feedchart.pdf

I water then skip a day then feed then skip a day then water, etc.

so your feeding your plants every 4 days?

I can see in the pics all of your leaf tips are burnt thats a sign of to much nutes and feeding them every 4 days will definitely cause nute burn
