Spider mites in flowering
Spidermites detected in flowering. Still no webs forming on buds but there is small damage on leaves. I have neem oil but don't wanna ruin my buds with bad smell and heard neem is toxic to humans. Rosemary essential oil maybe? I will be washing the buds at harvest.

Help!
The leaves are limp.. could anyone diagnose the problem of these plants? The leaves stand down, both when the pot is full of water and when it starts to dry. Could it be an excess of light or a lack of air? I had the inlet fans at idle!

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!

Spot on seedling Slow growth - Pest or not?
Planted some Pineapple Express Autos a few days ago. 3/4 are developing well so far but this one hasn't even gotten true leaves yet. It has this weird mark on it, has been like that since it sprouted so I figured it would be fine. Is this cause for concern?
