what is your airflow like? rust is often fungal related , and you mentioned you had thrips , which love the humidity and tightly squeezed in plants , in my experience with thripsOooops, I did it again.

yes. surface dew points and through temperature differences of so many degrees , causes water to condense and often the leaves become saturated and the fungal reaction can cause the rusts marks . and cold root temperatures and over watering never helps the situation either . i know people always say extra cal or mag , or both too , but calmag deificencies are symptoms and often not the causeHere are two plants that were very happy in a hot tent like it is in summer, 30C during day, 20C at night but got rust when they were moved to a very cold tent, 17C day, 13C night.

I will put some tube heaters in and watch them slowly recover. They are gradually greening up from the veg food and 24 hr light as you can see from the tops.
@strain_hunter i'm no expert but could it be your food or compost is a bit on the acidic side? Those patches look like when i bought Ericacious compost ( for acid loving plants ).
They have some really nice resin coverage. Like @shiva82 said, let them go another few weeks, it would be a shame to cut them early.
