    Maybe the Ph of your soil is extreme.

    Do you water with tap water?

    dark man that is looking bad. the other ones looking good though :) i think you should still get a ph reading, it will help working out whats wrong. you can get 2 types of cheap ph tester if you haven't got one, and don't wanna spend to much money. one you mix up the soil with this liquid and a bit of paper lets you know by the colour it goes the other one you stick the prongs in the soil and a meter tells you the ph ( also tells you moisture ) and both are only a few quid

    or if you can get really expensive pro quality ones but they costs loadsa dollar

    You must take the Ph of the tap water before you use it. The dissolved solids that cause akalinity do not evaporate. They build up in the soil. At a certain point- toxicity.

    $4 for an aquarium Ph kit at Wal-mart.

    If this is a problem, periodic flushings with distilled water and/or slightly acidic water will keep it from re-occuring.

    Where did you get your potting soil and what part of the world are you in?

    potting soil was bought at Ace hardware......it contains forest humus,canadian sphagnum(no idea wut that is) peat moss, compost, and pumice, the plant food spikes contain....6% nitrogen, 12% phosphate, 6% soluable potash, and some other stuff but all less than 1% each. I live in a nice tropical island so humidity is usually around 80% and its usually about 90 during the day and 75 at night. I am a cheap ass and i hate spending money. I will probablly leave them alone for a few days and see if they get any better. How is the soil and nutrients im using? And the large plant in the picture above is on its 4th week (always been on 12/12) and it has yet to show any signs of sex, its starting the get leaves where the preflowers form. How much long till i can tell sex....7 plants is a lot and im ready to ice the males.

    Those plant spikes aren't enough once the plant takes off.

    Peter's plant food ($3) works well. So do most off the shelf plant foods. You need more N for the vegatative cycle.

    The plants may or may not show thier sex with pre-flowers. Cutting back to 12 hours light is the only way to be sure.

    Damn Rocket ...talk about scaring the sh*t out of someone....You could have atleast posted the good plant first :) . Its strange that not all the plants got hit with this proplem...but those 2 do look younger! I had a simalar problem happen to me...i had some younger ones that got overheated...but the older one survived. Any overheating problems?

    umm their all the same age but now some r starting to get yellow spots on leaves, not dead patches just a lil discoloration....i was reading a lot last night and i came to the conclusion that it is a nutrient difficiency so i put a nother food spike in to help until i buy better food.....the two in the picture above are pretty much dead....not totally but more than likely wont survive, ill give them a few days and see wut happens, but i doubt they'll make it.

    down to 5 but the other ones arent bad. a few have yellow patches but i think its a minor nutrient difficiency, again i fed them to see wut would happen.

    as for overheating....i doubt it, the sun is on them most of the day and they LOVE it, at night they get a lil lamp just to keep the cycle goin a lil bit longer.

    those first two looked like they dampened off.Dampening is generally the first sign of overwatering. Feel how heavy your pots are after you water them. use this as a guage to water. when it seems to be getting real light weight- it's time to water.
    because the next problems you will see from overwsatering should be nutrient deficiencys.
    AS TO your little yellow spots, probably spidermites or thrips, they can kill- but outdoor plants can also build a resistance. These are traits to look for when breeding.
    IVORY LIQID DETERGENT has no phosphates in "the mix". phosohates in soap can kill a plant from ph imbalance. use only ivory or ivory classic liqid soap found at most any drugstore. mix about 1/4 teaspoon to a quart, put it in a spraybottle(or mix it in one) and spray as you shake the bottle. sopabobbles should cover your leaves somewhat if your mixed right.
    this applied every third day will kill the bugs without causing pronblems with your plants. Neem oil can burn like suntan lotion i wouldn't reccomend on full sun outdoor plants. Always spray first thing in the morning- before the sun gets too strong to avoid burning. SPRAYING IN THE EVEVNING IN A TROPICAL ENVIROMENT WOULD CAUSE BACTERIA AND MOLD CONCERNS.
    THAT'S ABOUT All i can tell you right now- i gotta get to work bro.
