Hi Umbre,
I am a newbie too, but learning fast about too much love! I am currently nearing my first flip.
It may be the angle of your pic, but did you plant your seedling near the side of your fabric pot or in the middle? The plant will expand outward on all sides.
I read this everywhere...cannabis doesn't like to be overwatered. So, as a long time veggie and flower gardner, I over watered my seedling! I found cannabis can go for quite a while without water. My plant would rather be dry than wet, even now.
I think you taught me why I should not use a cube to start seeds. It must be holding water longer than plain soil. And, it forced you to transplant sooner than you would have liked. I will definitely stick with solo cups.
Here are things I wish I had written to my self before I started:
What ever you do, do not give it added nutes at this point! Your soil mix has plenty to keep it going and it hasn't even started to use what is there yet. Later on, don't get impatient and figure more nutes are better. They aren't...especially if your are in good soil.
I made worm casting tea because I have given teas often to regular plants to boost growth without problems. Baaad idea. See my post titled Too much worm casting tea for pics. But I learned how to flush even tho I was afraid to do it and now my plant is covered with beautiful green leaves.
Once you are well into veg, look at the plant to see if it needs something. If not, don't try to help it when it doesn't need it. Vegging feels like forever on your first grow. If nothing is happening and you want to help, go start a tomatoe plant and play with it. I hope it is easier to be patient next time out!
Don't change two things at once...like lower the lights and give nutes the same day. You won't know which caused resulting problems. In fact, if every thing is fine, don't change anything.
Check your plant every single day for the whole grow. That CFL you added for extra light came down during the night. Luckily it fell next to the plant and not on top of it and it was only down for one cycle.
Lightly brush your seedling three or four times a day. It really does strengthen the stem until it is ready for a fan. Keep your CFL as close as you can...use the hand test...to avoid legginess.
Sorry I can't tell you all the things I did wrong in flower cause I am not there yet, but stay tuned I will probably have a bunch!
Good luck!
