Up until today my newly sprouted plants have been doing well. When I took a close look at the leaves today I noticed that there is something eating or burning the leaves?! Can someone take a look at what’s going on and give me some suggestions on how to stop this from happening?
The plants in question are White Widow and Zkittlez Auto. Both are being grown outdoors.
General comment: soil is too wet. Seedlings need very little water. A plant that size should get only a few ml of water a day. Limiting the water she gets will help prevent root rot or mold of some type.
On the leaf issue, are you misting the plant when the lights are on? Water droplets will act like little magnifying glass and burn the leaves.
Miracle Grow soils are very hot (nutrient rich) and MG is not a good choice for cannabis. It seems to be doing okay, but I would get her in a proper cannabis soil such as a Fox Farm product, Roots Organics, or Black Magic. MG has time release nutes in it that nuke your plant and submarine your pH every time you water.
I would get it out of the MG as soon as you can. Some people get away with using MG, but most don’t.
Definitely don’t feed it nutrients at this point. MG is too hot as it is. You could end up with nute burn.
The above mentioned good soils already contain fertilizers. A plant can go for 4 to 6 weeks after the last transplant in these soils without fertilization.
I expect the leaf problems are due to the misting. I don’t see any other problems.
