Mango Smile

Things are going okay still. The buds are just starting to fatten up a bit now. The smell coming off the plants is still weak but noticeably stronger than last week. It smells fruity and sweet. There are more yellowing lower leaves that dry up and fall off. I tried upping the amount of biogrow to increase nitrogen, but it resulted in some slight clawing of some leaves, so I decided to back off. I'm not really sure what else to do for her. It's not terrible so far. Many people defoliate a lot more leaves that what have fallen off. I guess a positive way to look at it is automatic defoliation. However, I would love to know what is causing this. Anyway, the light is up to 100% and I also increased the light schedule from 18 to 19 hours. I increased the nutrients following the biobizz chart, but giving only 50% of the amount.
