I have always flushed and always will...its a topic of debate i know as people say your starving your plant but the fact is your not if you only do it for a week or so your plants should have enough stored nutes to see them through the flush period, ofcourse im only talking hydro here..i have never grown in soil. All i do is reduce my ec when its about two weeks from the chop, ill continue feeding until the last week but by which time my ec will only be around 0.5ish, the last week is nothing but water. Yeah that sensi strain i grow is just plain old skunk #1, the lemon strain ive done was from DNA, i vegged that one and it was a cracking smoke i have one on the go 12/12 from seed but shes a bad un lol, shes one lanky bitch and nowt to look at but she will still give me some decent smoke for xmas......and shes all mine no sharing this bud out.... xmas or not.
