hey buddy the thing is you really cant just take one thing like that and say oh heres some cloudy tricomes, must be ready. its best to kind of combine all the different methods. its good to look at pistils to determine your general flowering time frame. if the majority of pistils are white and there are still new ones shootng out you are not done flowering. white pistils also mean there hasnt been enough time for them to swell up too. you want to have at least some red hairs/swollen pistils by finish. make sure when you use your pocket microscope that you check out the entire plants because different parts of the plant mature faster than other. the tricomes in the middle could be telling you to harvest while the ones on the cola could be telling you youve got a couple more weeks. i always tell people this but a better way to get a look at those crystal is to put a magnifying glas in front of your digital camera. it will allow you to take super close up shots and see the crystals more clearly. plus, you wont have to hold your hand steady over the plant or disturb any of the buds.
at any rate, early or not, i would love to have some of that mango for myself nice job you did a lot better than some of the more experienced people here
