I'm not a happy man today, I went to sleep early last night, was nackered. Woke up at 0200 in the morning asleep on the sofa, wife left the tent lights on, and gave no no feed. This morning 1 of them is going to die, and the other has got scorched yellow tips. When there this young, it takes 1 big enough mistake and they can die. So I'm not a happy boy, and the wife is in the dog house.
Hey man, you have a decent looking set up there. In my experience plants stretch for light when its too far. Try loving the light a bit closer, or standing the pots on a few books until theyre taller. I had one stretch like crazy and it sorted itself out when my friend put it under a bigger light. There are android apps that can measure light in lux. The one i use is called light sensor and it has no ads or in app purchases. For veg i think about 10000 lux is good.
