Yeah i’d agree this isn’t anything to freak out about, especially during week 7 of flower. Older fan leaves turn yellow eventually.

Burning plastic releases dioxins that cause cancer. If you can smell them, they’re entering your body and fucking with the DNA of your cells. I live in a small town where everyone burns their trash so I fully expect to eventually have these idiots claim the water or something is causing a...

Hard to tell yet but keep an eye on it.

If your other plants are still in veg and haven’t developed pistils then you’re in the clear, nothing to be pollinated.

If they’ve open you can assume some pollen has been released. When I grow males for breeding, they start emitting pollen as soon as the flowers open like that middle one. I’d cut off the nanners ASAP and keep a close eye on the rest of the plant.

Those look great! How far along are they? Are they as sativa-dominant as they appear?

They could look healthier but they’re not dying and they’re not stunted. Like I said, the curling could be an adverse reaction to your fungicide. I am not sure your leaves indicate a deficiency because most look healthy. The ones that look iffy are low on the plants and could have just gotten...

I’ve seen the serrated edges curl up like that from excess heat when I’m growing outdoor. Not sure what your temps are but it’s a possibility. Also not sure what they put in trifecta but I’ve also noticed stress when spraying for powdery mildew with my own concoctions. Some of your leaves look...

Just eyeball when they’re as big as you want them. Tough to say without knowing how much room you’ve got. But probably more than 2 weeks unless you want to keep them small.

If you can’t get an LED that’s intended for growing weed and need to use light bulbs, find the very highest luminosity LED light bulbs that you can.

Yeah you’re going to need a stronger light to flower, unless you are transplanting outdoors or are content waiting like half a year.

Judging by how convinced everyone seems to be that it’s actually a female flower, I think I’m the actual underdog, LOL.

You got it. Never seen a female flower start out looking like that and end up growing pistils.

Don’t water too much. Every day is excessive. Is that a bowl filled with moss?

Anyone care to make any bets?

I’ve never seen anything like that in my cannabis — it looks like slug or insect damage I’ve seen on tomatoes, etc. Why would inadequate nutrients cause such localized deterioration to the leaves? I don’t disagree it’s underfed but I think there’s something even more fucked up going on.

If it were a calyx, it would have pistils by now. Also wouldn’t be sticking out on a little stem like that. I stand by my initial assessment. Also, what’s been pointed out as a calyx is a piece of leaf. I’m not telling the OP to trash the plant — go ahead and wait to be sure. But don’t get your...

It’s a boy! The good news is, if you want to do any breeding, pollen becomes available way fast. I usually get pollen on male plants within 2-3 weeks from flip. At that point, you can collect the pollen and trash the plant or keep it around to collect as much as possible.

Looks like I will hit 14 hours of sun in late April. Can I still flower before then?

For example, are there any studies on the length of daylight that actually triggers flowering and revegging? I know it depends on cultivar but there’s got to be a range...
