3 weeks in flower, are my plants slow... pics

Well, today it's 3 weeks since I switched lights to 12/12, plants grown from seeds, vegged for 3 weeks, so 6 weeks total age. They showed sex about 2 weeks ago.

I expected to see bigger buds, I am a first time grower and I don't know if thats the tempo things should happen with.

Here is one of the plants:

not slow at all. looks good

Stop worrying, they look fab.

mine have been going for 3 weeks and the bud is no way near as big as that yet

be patient... the biggest growth seems to happen during the last few weeks before the trichs hit 50-50

I think my plants have a long way to go, they more and more look like sativa, and I know sativa takes longer than indica to flower

so I guess I have at least a good 6-7 weeks ahead

I hope the plants make it, cuz some of them look pretty sick, ph problems and nute lockups

the biggest key to your first grow is to be patient

patience and next time ve3g it for longer than 3 weeks, youll get a better yield

I am kind of limited in vertical space, so 3 weeks seems to be enough, with the current tempo the plants are growing they will just about hit the sweet spot - any higher and the light will burn them

the color of your leaves looks great, but it looks like you bit me under/overwatering just a bit. That's just me though, I'm no expert. Everything else looks healthy though. Good work.

well, I have some problems with nute lockups, but the damage is mostly in the bottom leaves, the top is fine

I try not to overwater, or underwater, I water every 3-4 days, as soon as the top of the soil looks dry I water, about 250 ml per plant, it usually dries out after 3 days or so

I'd say most of the problems I have are PH related, cuz the PH test I got is color based and I don't thing its that accurate, I will probably have to invest into some better PH measurement method
