Day 23: Topped just above the 5 pair of leaves.
Day 25: Removed lower first pair of leaves and cleaned up the branch. Only 4 nodes remain. Noticed a couple mold spots beginning to form a placed the light covers over the plant holes as well.
Sour has been slower than my other one from germination but within a day of each other. The cleaning up of the branch and removal of the first pair was enough to get this one to start drooping a little. I did a very light test on the biggest leaf which was weak. Root base is about half of the tank underneath and the roots are now coming up above the rockwool since I put the light covers on. Will begin LST next week pending a full recovery.
Day 28: Topped her for the second and final time taking two tops this time. Should make 4 main colas.
