Jerseyfresh39
started grow question 6y ago
What is the cause of the mottling on these leaves is it some sort of toxicity? Please look at my last diary entry (week 4) for info on recent feeding.

Hi
@booberry39
it seems to me over-fertilization, just give water with PH adjusted to 6 for a good day and wait for your plant to recover before giving it feeds again. good luck mate š

It's over feeding. Just give it plain water and let the planta feed itself on the soil

I'm starting to see my upper leaves turning a bit yellow in spots. I think I may be over watering. I've added 1 gallon water to 3 gallon pot leaves looked to droop a bit.

Leaf issue
Got 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. Iāve 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.

Brown specks on leaves
I've noticed small brown specks appearing on the lower leaves. Does anyone know what might be causing this? I'm struggling to keep heat down and humidity up due to the weather. Could this be the issue or something else?

Cal/mag def. Or nute burn?
I think I've got a Cal/Mag deficiency going on....or burn....not sure. Rust colored spots developing on leaves between veins. My pics labeled today, 11/9, show the progress. I don't think I'm overfeeding and growth is still progressing. Can anyone confirm?

Bright green spots and wilting.
I seem to have some wilting with some bright green spots on some leaves. I just potted up and she's at 20DLI, 0.6 VPD, 790EC @ 6.0pH. 75F, 71%RH, autoflower in canna coco pro plus.I turned my fans down a little since they were a little aggressive, so I'm hoping that's the issue.

Dark dots in leaves. Lamp burns?
I saw this dark dots in leaves but only she has it. She was exactly under spider-farmer sf1000 at 30 cm. Now I moved to other softer light at 40 cm. What do you think? Lamp burns? They're dry and curl up. Some images are edited for better appreciation but you have also originals.

Nutes too early?
The leaves of my northern lights look a little brittle and discoloured, maybe the small amount of nutes I gave were too early?

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.

White snipes on leaves... [ MAYBE THRIPS? SHOULD I USE POTASIUM SOAP? ]
Hey guys! Do you think these are thrips? The leaves have these white snipes already since some days ago. Also, If you look carefully, there are micro white things on some parts in the leaves that could be the thrips themselves. I'm thinking of adding potasium soap for this.

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.
