The biggest problem here is that you don't have a diary - so we don't have ANY information on this grow at all which make diagnosing some issue almost impossible. Start a diary... what are you growing? How old is it? What are you feeding? How much? What are the temps? What is the humidity? How big is the pot? How much water does she get? What's the pH you maintain? How many hours of light does she get?
Seriously, I didn't see your first question but the quality of the photos would definitely lend themselves to getting an answer concerning light... so if you start a diary, even reconstruct 2 or 3 weeks of a diary, this would help US help YOU... Once that's done, come back with your question... and tell us what problem it is YOU'RE seeing...
We WANT to help... help us help you....
