Turn off the LED lamp and take pictures using natural light.
Post more info about your grow so that others can understand the grow tent environment - what seeds, what soils, lights, watering schedule etc.
More important, though, are pictures.

@Russb788
Welcome to AFN It looks like a potassium problem but what is causing it? We need more info to make an attempt to help you correct the problem.
Please fill in this form: (copy and paste part is below, this first one tell what specifically to include)
-Problem: (brief description)
-Medium/grow method: soil; soilless-- coco, or peat based like Promix, etc. (please provide the actual product name); DWC, NFT, etc.
-Feed and supplements used: include brand, dosage/strength, frequency of feeding and watering (alone); method-- by hand, drippers, rercirc' or drain-to-waste,... N-P-K #'s too if you can!
-Water source: RO/DI; tap- dechlorinated-?..... EC or TDS reading; pH (don't bother with this on RO/DI, do bother with TDS/EC though to confirm it's working well enough)
-Strain and age
-Climate: night and day ambient T and RH%; res' temperatures; any extremes in T/RH% exposure
- Light used: HID, LED, COB, combo of,... wattage; light cycle hours (20/4, 18/6 , etc.); distance to tops....
-Additional info: PH in the root zone. How long have the plants been affected?...How fast did symptoms appear?... Anything else you think might be relevant..
--Pictures including WHOLE PLANT PICS, and troubled leaves.. use normal light or flash as other light sources ruin color rendering, critical for diagnostics! Turn off the grow lights.

Too much.
Too much light.
Too much fertilizer.
Back off on all for a few days and see what happens.
I've been testing the upper limits of food and light for autos in hydro, and my plants were looking a lot like yours from too much of everything.
When I backed off food and light health improved.
Deficiencies are rare when using a good fertilizer.

Salt build up definitely. Think you’ve got yourself the dreaded lock out. This will be a bit of a pain in soil especially if it’s got this out of hand. If ure in soil id just flush it with light nutrients or use florakleen. If in coco, use less nutrients and run enough solution through the plants medium until you get your EC/ppms back in range
