I'm taking your advice and tested it out on 1 of the 8. #2 was the one that made me think calcium lock instead of simple overfeeding because the green hue on the leaves looked pretty healthy but the entire plant was significantly more droopy than the others. I sprayed down the soil with a 1/2 gallon of RO water to moisten it up and then poured 2+ litres of RO water throughout. The idea was that moistening the medium would allow more excess material to flow out instead of water just escaping down the sides and through the drain holes. To my suprise the drainage water had a lime green/orange color to it which I guess it the excess nutrients. When I put her back in the grow room I noticed an incredible difference in the overall color of the medium compared to the other 7 girls. I can see that orangey (if that's even a real word) hue in the soil of the others. Like any good test I have to give it 24 hours to sit and if #2 shows decent signs of recovery then I'll have to flush out all the others. It'll be a pain in a$$ but so isn't normal gardening that doesn't have the fun results! Thanx for the heads up on double-flushing... I'd never considered it before and might do it anyways just to make sure I got all that crap out. Should I leave them be after the 1st flush and wait until the soil starts to dry up before the second flush?
