Hey, to me it looks like you sprayed your plants with something during when the lights are on. If so, you should never spray plants with lights on, always have it off. Nutrients burn leaves under the light.

Leaf issueGot an issue with some leaves turning this colour. Anyone got any input? We are nearly 7 weeks in, growing in compost and only feeding 1ml/ltr.
I’ve also attached a picture of the whole plant.
Leafs at the bottom seem to be turning, the ones up top all seem a good colour.

Why do my plants only have that light greenish yellowish look at the top and why is one of my plants also having those sick leaves at the bottom?2 of my 3 plants are a bit yellow-ish at the top since about a week. Plant 1 also had a couple of sick leaves at the bottom that I did remove. Those leaves had brown/dark spots, felt dry like paper, had very purple stems and did smell more like hay. More info in my report.

Is this septoria or alternaria?
The plant is doing well, buds are not affected (at least not now) so I hope it’s septoria. Few weeks till flowering complete, do you think I can carry on with it?
Please tell me it’s septoria and not alternaria. Thanks to anyone that will respond

Hi growdiaries,
Got a couple of issues on my plants here. The last 4 pictures show the problems, firstly there are holes appearing in the leaves and it looks like something is eating them. Haven't seen anything alive. Also a few spots appearing. Mould? Had bad air for a bit.Week 5
