How much longer should i go?

Hey fella, without a diary for reference its kind of difficult to state, in terms of harvest, do you have a jewellers loop or magnifying glass that will let you get in close to check the trichomes? They are your best indicator of harvest. From the look of the pic I feel she has a bit to go yet but again I don't know how long she has been growing, nutes, strain etc.. to me the best advice I got when I asked the same question is... Look at it, does it look like a green banana or a nice yellow ripe banana, now I'm not saying malnutrition the plant to get to the "visual" result faster, but let nature take its course, look after her and when them trichomes start looking "frosty" that's when to start paying attention everyday, hope this helps, good luck, happy Growing 👍
