Brown spots
Moznurseukstarted grow question 2 years ago
Can any help me diagnosis what's the problem with my plant. Only got 5 weeks left till harvest. Brown spots started at the bottom of my plant and worked its way to the top. Any help would be much appreciated. You can have a look at the diary to see what I'm feeding and watering.

Looks like calcium to me. As you are growing in soil I would add in some chicken manure if it was me or brew up an egg shell extract. You can also use some ready to use CaMg supplements as a quick fix. Your PH is on the high side for soil based grow as well, I would try and get that down a notch to 6.4 if possible given that its in a pot vs the earth. Also side note a lot of things say potting soil but in reality it is soilless as it contain little to no soil. Please double check your bag if it comes from one and confirm it is not just peat and perlite or something like that.
Good Luck & Happy Growing.

High Moznurseuk,
The spots on your leaves are caused by calmag dificiency. You need to add some calmag with your nutritions.
Also make sure that the pH of your water is right. You can measure the pH of your water and nutrition solution and this should be close to 6.2 on soil.
You can also measure the pH of your soil using demineralized water. I always do this just to check if my soil is still in the right pH range. This is really easy and can be very helpful.
You need a measure cup of at least 250 ml. Then you add 150 ml demineralized water and you add soil till you reach 250 ml. Let it solve and stir well for a minute. After this you can use your pH meter to check the pH from your soil.
Happy Growing! 😋

@Moznurseuk its the beginning of a calcium deficiency mate usually due to the ph being a bit too low
with soil use calmag sparingly as it doesnt work as quickly as it does in hydro or coco

This is the start of a calcium deficiency. Drop your pH to about 6.2-6.3 and add some calmag... you should be fine!
Good luck with your grow - and thanks for the diary and information! Sorry I was a little short with you before - the heat was getting to me! :-D

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

Wet shiny spots on leaves.I find occasionally such wet shiny spots on leaves. Any idea what the root cause and how to fix it?
They are not sticky although look like.
I cannot say whether they smell because smell of the leaf is too strong 😶

Stains on the plantHey guys,
first of all, thank you for taking the time to read this. I started growing my first canopy and since I am little excited, I started before everything I ordered arrived. For that reason, I am still using the soil I used while planting the seed. Did I fuck up already?

Brown spots on top leaves - nutrients, light or something else?She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each).
3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves.
I suspect this could be light burn or nutrient related.
Any ideas? Pls help

Insects, Mutation or related to my early nutrient burn ?Hey I noticed that one leave is looking like it has been eaten by something.. I checked every plant and also used yellow stickers, but can’t seem to find anything.
Is this related to insects or could it be something else ? (The plant had an early nutrient burn, but recovered)
