Severe rusting on edge of leaves

[dwalkama]

Hey guys,

What do you think this is? I just did a full flush and gave it some light nutes to try and fix the problem about a week ago, but I think it's getting worse. The plant also has really thin stems. Thanks for the responses!

Can you turn off the blurple and take pictures under a more normal-tinted light? I'm about (optimistically) half color-blind anyway, so pictures of sick plants all done up in varying shades of <BLEEP> don't really show much. It appears as though you have several symptoms - including the veining of your leaves being way darker than the surrounding leaf tissue - but all I can tell for sure is the crunchy ends and the absolutely massive case of leaf clawing.

Perhaps a K deficiency?

Sorry about that, here they are.

What are you giving for nutes and what is your ph going in and your ph going out?

Looks to be starving for potassium. Nutes? PH?

Or maybe not properly flushing???

Fox farms + calmag and ~6.5 going in. I don't check the runoff because I also use ffof which is heavily buffered and the readings coming out are usually very acidic

How acidic? Ph run off in soil should be 5.6-6.0 to be optimal. If it is a lot lower you have a problem. Top dressing and amend into the top inch or two with a little dolomite lime would help.
