Help needed first time grow when to harvest

In flower since 15 feb outdoors in 7 gallon soil bag receiving 6 hours max sun since a week but temps exceeding 32c but breezy and no effect on leaves . Help when should i harvest cz heat might evaporate my crystals. Buddha og is the strain.

You're, what, 45 days in? Let it ride.
Heat won't "evaporate your crystals" except when you use a lighter on a bowl.

The heat will not evaporate your tricomes..."crystals", unless it gets above 200°f, then they'll melt. Your girl looks good. Get us a pic as zoomed in as possible. Need to see those trichs up close.

Glad to see the replies lots of love. I guess two more weeks?

That's 59 days or so. Depending on strain, that's the time to start checking development for harvest
