Harvest in about 7-10 days?

It’s always definitely hard to tell in pictures and you have to trust your naked eye with what you see. You definitely seem on the right track. You wanna check multiple spots on the plant for cloudy and amber tricromes. As long as they are no longer clear you’re in the window for harvest. The more you let the amber tricromes set in the weed potency is on the down grade but for a trade off of a more developed flavour profile. Some people prefer to harvest when all tricromes are cloudy with minimal amber tricromes to have the most powerful effect the plant has to offer. This also comes down to personal preference and what you want out of your grow and end result product. Me personally I’m ok with harvesting when I see a 50/50 amber and cloudy tricromes. You could potentially almost harvest now but I think you should do the flush and harvest after that is complete. I think you are possibly a bit late on starting the flush. But all in all for a first grow, you did well and you’ll soon get to enjoy your harvest.
