Can you get two plants from one seed?
What is this little surprise? Do I have another viable plant or is this just a cotyledon? Also, when transplanting, do I bury the existing cotyledon on the stalk? Thanks!

Spraying the leaves
While I was checking my plant I saw these “black stains” like the plant is “half-bitten/scorched”.Is it possible to burn my leaves and create this effect after spraying them with nutes. Blacks spots were created today after I sprayed them and there were drops on leaves for hours

browning leaves
Anybody have any idea on the cause of my leaves getting brown spots and curling at the tips? It's really just on the big mature leaves and leaves near the buds. Any smaller and younger leaves are still fine. Maybe a nutrient issue? Or is it just that its close to harvest time?

Hey, anyone got any idea or clue what's going on?
I thought it was a manganese or iron deficiency from an early watering with high pH. Though I've fed/watered my other 2 plants pretty much the same stuff but she seems to be reacting really poorly. She seems to be getting better slowly.. I think. Thanks for taking the time. :)

Green house cheese 1 Rusty plant
I've been doing well, but one plant doesn't like so much cal/mag I think. I gave 10 ml each 10 liter. Will stop giving calmag now and only water for a few days. Can anybody think a bit with me about whatsup with this plant? It's the most Sativa looking plant that doesn't like it

Should i still not worry?
Should i still not worry about this? Read week 2 and the growquestions of extra info if needed. This is only on the lowest 2 leaves. The top does have some spots but they're clearly not dying.
