Dude...

Lose the lights. The sun, when covered by clouds, is far more powerful than your 500 lumen lamp.

Those first two pics should be repotted about halfway up those stems. You are growing stick plants.

The 3'rd pic looks just great.

Lose the light.

Keep them in the sun if you can, cloudy or not.

Good Luck
HARDDON Reviewed by HARDDON on . Yellow Spots OK, I have noticed that two of my three plants have little yellow spots on them and they are gradully getting bigger. I am growing my plants in Jiffpots, and transplanting them tomorrow. They are three weeks old and I have applied a 1ml/L solution of 20-20-20 fert. once, four days ago. I am also growning out side. Here are the pics, if you look closely you can see little yellow spots near the end of the lowest leaf in the two pictures. The over head view is of my third plant and its centre Rating: 5
