Why are some growing and some not?

look at them reaching up! This is a clear indication that the roots are now healthy and growing.

Definitely!! After reading through your post again and watching @CannaBeardGrows video, I can finally say I understand the difference between wet/dry cycles both visually and by odor!

If you haven't built it you might want to think about either lowering that 17" shelf down lower with more space in the top, or just nix'ing the bottom shelf for one taller grow space. Jack likes to stretch and you might get really tight on height unless you flip them to flower while not too big.

Hey guys here is some of my latest grow, I have a little problem, though. The leaves I'm holding in my hand are curling along the centre vain, what could be the cause of this?

I have to say the one plant that is curling has been up-potted but the other one is in the same pot as before and it also a little smaller than the two next to each other. It is also very cold here but there is a temp controller set to 24 Celsius/75 Fahrenheit as well a fan on lowest setting turned above the plants circulating air.

This is the one curling but still in the same pot

This is the other one that is curling but I have also up-potted him.

I flipped it completely. I have about 66 in grow space now.

Try turning the lights off for pics, that burple color is pretty brutal and prevents being able to guess about anything on the plant condition.

The big one, up-rooted 2 days ago. The tip was burned almost 3 weeks back, the halogen light bulb i was using got to close

The smaller one that is still in its original pot, the bottom leaves are curling more than the others.

So I just want to thank @Emilya @Old Salt and the rest for their help in the early stages of my first grow! Here are some pics of my babies! I'm 2 weeks into flower and they are starting to look amazing!!! I mainlined them, two plants 3 times and two of them only twice so my grow was a little slow but damn they are pretty!!!!

PS I've built my current steal frame tent myself for only $35 and 3 rolls of duct tape so if anyone is interested please just ask I'll be more than happy to help.


Here they are enjoy!! This one was taken today!!

So I know this is bit after I have harvested these Jack's but I eventually had 300W worth of CFL's. The total harvest in the end was roughly 90g dry weight (trimmed) from 4 plants. I calculated about a 40-60% loss in mass due to moister etc. The THC concentration on the other hand was insanely high as many of my fellow friends (seasoned smokers) got hit hard with only a little amount and some even called it the strongest they have ever smoked before.

So with regard in stressing the plant out, cfl's are great due to their uv emittance and high heat generation but in terms of yield one must not expect much. Also I had no light leaks no problems what so ever yet they still started herming. So I had to cut flowering early and harvest my flowers. Luckily many of the flowers were ready to harvest but few still could have gone a week or more.
