That last quarter-strength nutrient feeding seems to have taken well. Amnesia is bulking up slowly, and isn't letting go of as many dead leaves today. I am removing any crispy leaves I can find from Trainwreck as well. She isn't letting go of any leaves like Amnesia is, they're just ugly as sin. Oh well, they're doing their job. I am keeping the humidity to match the current temperature according to the VPD charts, like every week, so I haven't been lowering the humidity over time because of the heat in the tent.

Leaves are looking greener today. Just keeping an eye out for any loose leaves ready to be removed from either plant. Not many so far today.
Most likely you have an imbalance of either calcium or magnesium and this could be most likely be related to ph and uptake issues.
Other than that it's just natural aging process.
