Welcome to OG, @Cinderella99 !
Be sure to stop over in Introduce Yourself @OG (Part 2) and have yourself a nice warm welcome! Maybe include a link to this topic!
Are you growing in soil? Coco?
Are you alternating water and feed at all?
A couple useful topics I’ve found on these things:
Sick Plant - Ask The Community
Nutrient Disorder Problem Solver by Jackerspackle
If you post in the first one, you may find more help at the ready. The second is a useful guide to keep handy.
Hope this bit helped point you to some folks with a better eye for these things!
Stay up!
