Bugs or Calcium deficiency?
MamaSheastarted grow question 4 years ago
Bugs, Calcium deficiency, or something else? A few brown spots on one fan leaf (3 of the 5 leaf affected). Nothing i can see on magnifier. No webs. Nothing noticeable on any other leaves; either plant.

Looks like calcium defiency, some sort of cal-mag should do the trick.
I use general hydroponics, cali-magic, 1-0-0 for autos as it is not as high in nitrogen as some other brands.
Hope this helps👊

I'm by no means an expert, the opposite in fact but I have noticed similar spots on mine and every single time it was "water lensing" focusing the sun (i'm growing outdoors) and burning them. Nutrients will always burn the leaves if you are not careful while watering. In my case the yellowing never progressed beyond where it originally manifested and and I haven't had any new yellowing since I started paying the necessary attention to watering.
Are you sure it is not something leaf specific? If it's insects try looking underneath the leaf, this is where most insects leave their eggs not atop. Let us know how it progresses. Cheers!!! 😀

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 😶
I can rub them off with the thumb with no sign

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?

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.

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).

Are CBD-Strains less nutrient-hungry?Hey Guys, i experienced that these strains like a lower EC/TDS. Every time i went over 1.2 EC (600ppm TDS) they showed signs of over-nutrition, like very dark green leaves and reddish brown leavetips. What are your thoughts on this? Are CBD-Strains less hungry on nutrients?

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?
