Hey Ith, this is where your count on your plants comes in. You made a mistake but you can correct if you're careful. First you should have kept a log on all gardens in that area, what day they were started so that you can determine how many days old. Alright well depending on how long you took to plant them it could vary between 2-3 weeks to a month. Also, if you cut down 4 plants because they were taking up too much light over other plants, this is where topping comes into play. Find the highest node up and clip it, it will split into 2 colas, wich means you will have made 1 cola into 2, wich also means you'll have a better dryed ammount. Also we did talk about spacing earlier in this thread, I think now might be the time to start moving some to either A) Farther away or B) Make another spot off to the side useable for these plants, remember space is crucial so when you re-plant them think smart. Also becarefull of roots when you're taking them out. Slow and steady wins the race.

1 Oz(Ounce) is 28grams on the dot, you can get like 30-35 on a good buy but if you just want smokes, 28grams = 1 ounce.
