started grow question 4y ago
What is causing this and can it be fixed? I was giving her some nutrients not a lot, and I haven’t given her any in about a week. Only water now and it started popping up after 4th feeding.

Odd leaf bitten?
Hi All, Noticed the odd leaf like this that looks like something has taken a bite of it. It is only the odd leaf. I had some fungus gnats a few weeks ago which are now gone. Is there something else doing this and do I need to act? Thanks

Light, nute, wind or heat burn?
Im getting some browning on the serrated edges of the leaves, moreso on the upper fan leaves, but not on the sugar leaves, with some cupping of the upper leaves and the ones directly under the light are getting a lighter color overall. Any guesses? Light, nutes, wind or heat?

Chewed up leaves
Wondering if I should be concerned? They have just entered flowering, I have noticed a few leaves bearing this issue. I use ties which have ripped some leaves due to me not being gentle, and I spray a mild cannacure solition regularly.

Dry yellow tips
I've noticed a few leaves have developed some dry tips on the ends including some of the new ones coming through. Can anyone tell me what could be the problem? Feeding bio grow 2ml per l at the minute. Is it a deficiency of some sort? Or nutrient burn? Worth sticking to water?

Please take a look at the last photo of week 10, the close up of a cola. Does this appear to be the start of a K deficiency? There is tip burn on some of the plant as well. Refer to my notes with watering issues for past 2 weeks. All nutes listed ph ppm are correct. Thanks!!

Nute burn?
Got this discoloration on the tips and edges of some leaves. Believe it or not, I've never had nutrient burn before so I'm not sure if that's what it is. If so, flush with ph'd water?
