Q: How do you manage stretch during early flower?

Spider mites and aphids appear under heat stress. Inspect leaves weekly and introduce predatory insects or use targeted miticides.

Cure for 2-4 weeks in glass jars with daily burps for the first 10 days, then weekly checks for humidity.

Perform selective defoliation to improve light penetration. Avoid over-pruning during late flower.

SCROG maximizes uniform bud sites and yields. Combine with LST during veg for controlled height.
