What happened? Is there a problem now?

if such fade started just now, you were almost at time with nutes, she missed a bit. think has 2 more weeks to go, that overall look would be almost perfect for harvesting time, now she stayed hungry and consumes hereself. take off dead or most yellow leaves, they are not bringing any use and i see some covering lower buds, less thread to bud rot , better air circulation. trichs mostly milky on buds from what i see, but buds not developed yet, so i would wait 2 weeks or so.
