Weird forms appearing on some of the leaves
Killuminatianswered grow question 4 years ago
I had this problem too, these are leaf miners.
You should def. take action. You can crush the larvae by pressing the leafs with your fingers.
Also you can use a mixture of neem oil to protect your leafs and kill the miners.
You can take a look on my diary where i asked the same question and got some really good replies on it.
I used the neem oil solution and it works well as of now.

are you using tap-water or RO water? I've seen similar in my Plagron-royal mix grown Hindu Kush when i used RO water without calmag.. ever since the prefertilization ran out and i started feeding manually (with calmag, because i use RO water) i haven't seen these marks anymore.. i asked at Plagron if calmag should be added to the water when using RO water when using royal mix, or if it already contains calcium and magnesium and i was told that i should add a little bit with RO water..

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).

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.
