They are just in soil and ive just been watering them every couple days. Cut the lower branches completely off?? Also what kind of dtuff should i use to help them bloom? Thank you everyone
No no don't remove any whole branches, unless they're very small and are growing into the larger ones you have there.
This picture shows what I'm talking about well...
So you see between the main stalk and the stem of the fan leaf where you have the pistils/preflowers/calyxes and the new leaves coming out? Flowers are going to be forming here, and basically anywhere there's a junction like this on your plant. So when you look at the bottom of your plant and the branches that are down there, and see growth like that you know a flower will be there. Then think about if it will have good air flow, good light, etc. More likely than not it won't, and will just grow little "larfy" flowers that are basically a couple of calyxes. Not a big deal to leave them but they do sap resources from flowers that are further up on the branches, particularly your "tops" which should form colas ( where the flowers at these internodes cluster together to form one huge bud ). Midway along the branches are going to be more popcorn sized buds... Well on the plant they'll look more like golf balls, but once dried they will be about the size of popcorn, and the further down the branch you go the fluffier and smaller the buds that will form there will become, people call those larfy. Since the area under the plant won't get a lot of sunlight, they're really going to be robbing more resources from the buds in the middle and at the tops of the branches than they're going to be worth for smoking, so what I like to do is to go and just remove every little internodal branch that's forming near the bottoms of the branches where they connect to the main stalk. If you've been growing them wild with no pruning chances are you'll have quite a bit of spots like that which will produce that larffy bud. It's really not something you NEED to do, but with what they will take from the tops and middle buds likely won't be made up for in terms of getting more THC so don't be tempted to save them thinking it will help you get as much as you can. It's most certainly a preference thing. Try it on one and not another, or one branch and not some, and it will give you a good idea of the differences
Anything with a higher ratio of P and K versus N should do fine all through bloom. You will see some stuff with higher P or K meant for mid or late bloom, but I wouldn't worry about that much. If you don't have a problem with synthetic nutrients, Crystal Burst is a great one that's 0-15-15, meaning it has zero percent nitrogen, 15 percent Phosphorous and 15 percent Potassium ( periodic symbol being K ). Your soil looks like it's decently nutritious, so follow the directions as if you were using it with other nutrients--so half of what's suggested if I remember right.
