Not sure why but I'm guessing your pH was a little high 2 weeks before this. Ok did I bingo?

sure ill play along, this looks like too much nitrogen at some point or this plant is a very picky eater, either way less nitrogen

Help, I'm getting yellow brown patches on the leaves! This has only occured over the last few days and up to then the plant was really healthy apart from slug trouble. It's getting 1.5ml of both bio bloom and grow per litre.

Any ideas on this?
I'm guessing this is some sort of deficiency. Some of the spots are rust like and occur and young and old leaves. Any opinions? Advanced Nutrients 3 part. No supplements.

Brown spots and yellowing leaves.
I’ve just started to get these brown spots and yellowing leaves on the top leaves of one plant. Not sure what it is, potassium or calcium deficiency. Soil ph is 6.35. Water with regular nutrients at a ph of 6.5.

Brown/rust spots have been increasing on one of my 3 plants. Appearing on upper and lower, newer and older leaves. Does not appear to be a light/heat issue. Treating it as possible Cal def by increasing cal-mag nutes.

I am noticing a weird discoloration on one of the plants. It's starting from the edges of the leaves and growing towards the middle. You can see it in the last photo. I have looked on a few guides, but I haven't been able to find this issue. Can you see what's wrong?

Leaf Problem persists and develops, advice?
Ok, I've noticed the leaves now becoming mottled, and browning. It is on the sugar leaves now, and I'm concerned over botrytis! Last question on this, the consensus was foliar spray. Any ideas why it seems to have progressed?? What should I do?Thanks all, so much! 🙏💚☺️🌱✌️

Cause for mottling leaves?
I think this mottled leaf coloration may be due to slightly high pH or just stress from the repotting over the last couple of weeks.. Most leaves are fine but a few look like this. Any thoughts?

Help Identifying Ailment! BlackBerry Auto on week 6! Nutrient deficiency? Cant find anything online similar.
This is my second grow since switching to hydro. Growth has slowed a lot. Leaves are getting brown spots and almost look like they're being eaten but no pests can be found. No root rot, I dont think I'm over watering them. Since I started hydro it's been a real challenge.
