My plant is short and wide and the center is prett...

Watch carefully what happens between those dense leaves and take care of a good ventilation. During last weeks of flower take care of humidity, it should be somewhere under 60%. Mould is tricky to find on your buds, first signs are yellow/brown bud leaves. If you see those leaves, take a closer look on that buds. If you can pluck it out easily, check that bud for mould.

Leaves that are touching each other will form moisture between them, and thus they become more likely to contract white powerdery mildew. Untrained bushy/leafy plants with lots of new vegetative growth are especially prone since they will often have their leaves mashed up against each other as they try to reach toward the light. But as long as there not overlapping and you have good air flow and exhaust you'll be just fine. Also keep humidity in check is a must

A too dense foliage can have a high humidity risk. Check those leaves, if there traces of water then yes, it is a problem that should be Taken care of by some defoliation.

Hi @medicalflyer! Proximity between colas can be an issue, because airflow and light penetration are not at their best, but in your case I think you're just before the red line, unless you have some relative humidity issue (high RH during late flowering) I see no need to defoliate. Keep those sugar leaves to make some canna-butter or some bubble-hash! Hope this will help, keep us updated and happy growing 👊
