Cannapprenticestarted grow question 5 years ago
Hi, After I topped, the new growth tips started growing vigorously, but the leaves are weird.
They have a loose&floppy appearance, the serrations on the edges are very wide and one of the leaflet didn't even grow 1/5th of the size of the others..
Do you know what it is?
thanks!

Looks too me like ur nitrogen toxicity is starting to lead to nutrient lock out! Give ur medium a real good flush and get those nitrogen levels under wraps and it should clear up all ur lock out and deficiency issues!

A boron deficiency in cannabis is relatively rare unless a plant is underwatered or in a really dry environment, and is usually accompanied by other types of nutrient or pH problems that appear as problems with the leaves.
The first signs of a cannabis boron deficiency is abnormal or thick growth tips along with brown or yellow spotting on new leaves. Sometimes a cannabis boron deficiency (like all deficiencies) can be triggered by stressful conditions and may clear up on its own after the period of stress is over.

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).

Light Green Color on Seedling GrowthThis question is regarding the photo of the seedlings below. One of my seedlings is beginning to turn a bright green color in the center near the new growth.The other is staying a dark green and I am wondering what could cause this as they are both being cared for evenly.

Overwatering? Barneys Farm Wedding Cake Auto in soil/cocoIncreased watering to 1-1.5ltrs/day since it's in a 10 ltr pot and quite large and was bone dry every time I watered. As drooping started I stopped watering completely thinking I overdid it, this was 3 days ago. No signs of recovery until now. Overwatering/root bound?
