#1It’s been about 6 months since I planted my first little plant, and about 3 months since flowers started appearing. Approximately how much longer until I can start harvesting?
#2You need a jewelers loupe or pocket microscope to look at the trichomes. It’s really hard to tell from the pics.
#3The best thing to do is take a magnifying glass or a pocket microscope and look at the trichomes on the flowers (not on the leaves), and if almost all of them are milky white, you’ll get a Sativa high. If you wait a little longer until 20-30% of the trichomes are amber colored, it will be an Indica high (Couch lock). Everyone has their own preferences on how they like it. Now you know how to recognize it, the decision is entirely up to you.
#4If you have been flowering for 3 months you are more than likely past the harvest date. Most will finish flowering in 8-10 weeks. You probably have a large majority of amber trichomes.
#5I would think letting them flower that long You’re already and what they call the couch lock stage. You had some very great advice given above by the other members about getting a jewelers loop to watch your terpenes.
