Deficiency, toxicity, bugs?

If you give more information you will get better replies and help. What soil and nutes are you using? Lighting? How old are they? Do you have a shot of the whole plant? Do you measure PH?

Fox farm ocean forest potting soil and fox farm nutrient trio (big bloom, grow big, tiger bloom) but haven't used nutes yet since the soil was fresh, 5 42w 2700k cfls, month and a halfish old, View attachment 3017721, I don't currently have a ph meter/tester... strain is green-o-matic from green house (autoflowering) and she's about 3 weeks into flower.. I kinda figured it was a natural cause from flowering but I wanted to make sure...

Yeah, that leaf is the oldest true leaf on the plant and is normal for it to die / be replaced as needed by the plant especially as it gets older and is further away from the light or shaded.

Your plant is looking great IMO. You could start feeding it at 1/4 dose and see how it responds, at a month and half it will needed it even in FFOF.

Should I use all three ferts together or just the bloom ones?

Whatever ratio you choose I would have half the mix include the Grow. That is just IMO. I don't know what schedule the product recommends...

I would slowly move up the ratio of bloom to grow nutes in the weeks ahead as well as increase the overall amount fed. Maybe do some research on what others do when feeding autos as well as when using those nutes specifically. Personally, I use supersoil and just add some mild bloom or nitrogen or Magnesium when needed so I am not an expert on using those nutes.

Using less than "optimal" is way better than using more IMO...

Good Luck
