My buds are still small and I’m in week 12 of flowering

[Bloomy1999]

I don’t know what to do I’m new at this and my buds haven’t been getting much bigger. I rotate nutes and water every 3 days with about 25 percent runoff. Homemade grow tent in basement with fan for exhaust and space heater to keep temps around 65-70 degrees.

 

[Hollatchaboy]

My guess is your light.

 

[PopAndSonGrows]

Temp too low, and lacking light intensity. Even though you're switching from plain water to feeding, they still look to be overfed/nitrogen toxicity.

 

[DrDukePHD]

A grow tent & an oil filled heater (see: Newair 400w thin) would keep your costs down. Space heaters use mega wattage. Way easier to heat & light a small tent than a whole basement. What kind of light ya got?

I try to keep my temps at 80F daytime & 75ish night.

 

[Budzbuddha]

Lack of light / wonky growth / no lateral growth
Overnuted ( glossy green leaf ) / malformed flowers

Toss it - start over.

 

[MickFoster]

Shitty lighting.
You won't even yield a joint from that plant.
Start over.......but get better lighting first or you'll end up with the same.

 

[Nope_49595933949]

Shit lighting and too cold.

Week 12 of flowering ?
You need to do some research
I would definitely not start another grow without doing a journal so you might get some proper help

Get rid of the low wattage blurple and upgrade to a better light. Work to get your plant environment temps in the 75-85 range.

Thanks all, great input I will take all the info and apply it my next grow. I’m in the process of building an 8’L x 6’ W x 7’H room with 6 mil poly sheeting for walls, exhaust fan and better heat. I do have more lights I was just afraid of having to much light

If you have a concrete floor make sure you insulate your floor.

Why don't you tell us what lighting and heat your having to use currently before you start throwing more money at it , or you'll be in the same position next grow too

You sure you don't want to have a successful smaller grow first?

It kills me to see blurple when a 250w hps would kick its ass all over the place.

I can't see the size of your tent, a hid light will cost around 100 bucks, it'll give you heat and far superior results for peanuts.

I'd recommend you take @Nope_49595933949 advice and start with a small successful grow.

 

[Rurumo]

I agree with Nope and Star Dog, but I would get a 600 watt HPS if you can, they are cheap. You need more heat than the heater is providing, and you need more light, so why not combine the two? You might even just go with 1,000 watt HPS and just run the heater during lights off. You might find you are using the same amount of power as you are now with that blurple and the space heater, but you'll have the light you need to grow properly. Good luck!

And here's a great place to begin your research. A lot of us started here...

Generally I don't think we're doing good enough in our plastic environments.

Look at your temps as example. Those are fall temperatures. And what is your humidity at? Does the tent air feel like thick Summer air or thin Winter air?

Have you ever been to the botanical gardens or butterfly exhibit? I think that's the environment we need to emulate. Tropical. 75°F minimum to 81°F+/-.

I'm root'in for you!

 

[Bloomy1999]

I currently have two more plants growing great. Made some modifications, my heat is stable @75 humidity is 55-60 I will insulate the floors as well

HPS or better LED?

 

[Bloomy1999]

Led full spec

 

[ComfortCreator]

They will grow a lot faster above 70, and even faster at 75 to 80.

The airy result is as said many times lack of light. 50k lux is a simple target that will yield great results.

Asking and improving is the game. Well done and nobody snarked you it must be a new year lol!
