Royal Gorilla Auto

Leaf down too much water.. Browning on tip of leaf too much nutrient ...leaf tip reaching up light too far....holes in leaf 85% of times its pests of some kind.. You'll have to inspect the under side of leaves and check soil for fungus or mildew.... GOOD LUCK FRIEND👍👍💪💪🍻🍻🍻

Listen to the g slave my man

hello my friend most do not train auto flowers because any stress you cause them can add weeks onto your harvest time it can also effect the yield in a negative way the reason is autos have a predetermined life cycle meaning any stress you cause her will take time off her in built clock forcing her to work harder to repair from the stress when she should be concentrating on growing. My advise would be to untie her and just let her go. If you want more yield I would look into the pony tailing method of training this does not stress the plant no where near as much as LST does :) Best of luck my friend keep up the great work :)

Looks like a pest or some has hole punched your leaf lol I would not advise stress training auto flowers they dont like it can cause them shock and stunt their growth so if she's not going as quick as you think she could that is probably the reason. untie her a leaver her be and im sure she will repay you with a fat harvest :) Best of luck

Your leaves are a really nice shade of green, so i would say a slight deficiency, but if u are in flower its pulling nutrients from old leaves to new, so u could up your nutrients but its totally normal for that to happen. Good luck growing!

I’d say it’s not toxicity, but I won’t pretend to know just by the pic, just that it’s not toxicity
