Zkittle auto needs your help

[Hebrewdiver]

Greetings fellow farmers, I need help in diagnosis this problem. I 'm growing zkittles auto in soil, AN nutes, under 150w actual led light. The girl has been growing for about 5 weeks from seed. At about 3 weeks I was trying lst and accidently broke the main stem. I managed to tie it up and it seemed to heal pretty good. but a week later I started noticing browning on the edge of leaves and browning and yellowing on the leaves.(see photos).. Hoping someone can help as it seems to be getting worse. if its a nute issue should I flush with plan water. Oh yeah one last note I think it started happening about the time I added flower fuel to my mix, could that have had an effect? Thanks in advanced. The white on the leaves is foliage spray

I don't grow autos, but she just looks hungry to me. She's just begun to flower, maybe a little too soon for a bloom booster.

Basics. How much water how often? What is your soil? I would focus on the plant healing itself. Never much time to head an auto. But feeding it a bunch of nutrients could definitely cause issues. What are you feeding? How much? What kind of light schedule?

ditto OG above

what size container? maybe too much plant supported by too small of a container…

perhaps a bump in nutes? But really need better pics in daylight…. or white light
