    First grow, how much longer till harvest?

    that is sever nitrogen deficiency. Look at the way it started at the bottom and affected the old growth... Also, why haven't you cleaned that plant up? Any leaf over 70% yellow should be plucked. I bet a slight downward tug on most of those leaves would pop them right off... or a good shake on...

    how cold is too cold???

    Stomata aren't a hole that can be "exercised" by different water temps causing them to be stretched in some permanent fashion like a rubber gasket that has been stretched out...

    Cucumbes

    If you are growing under heat lamps, you are using the wrong type of lighting.

    how cold is too cold???

    You made all of that up. That is not how transpiration works, AT ALL. While it is true that cold temperatures (under 60) inhibit water and nutrient uptake, it is not because the coldness is thermodynamically radiating up through the plant and chilling the leaves. Explain again how you...

    how cold is too cold???

    No there would be no locking out of any nutrients at 60 degrees. Any plant that has green on it has stores of nutrient.. Leaves shouldn't droop due to cool root temps. Dr. Howard Resh and George Van Patten (jorge cervantes) recommend hydro nute solution temps of 60-75F. Duder, maybe you would...

    Soak in bleach at 4PPM and then rinse. Don't buy into the lazy consumerism and paranoia that is going on here..

    First grow, how much longer till harvest?

    We're not talking about the MG water soluble fertilizers; we're talking about the MG soil with the slow release fertilizer in it. You can use water soluble fertilizers, including MG, at EC double .75... Mature plants would be lacking at half-strength (.75EC) levels.

    My Seedlings are always dying!!

    HID lighting is OK for seedlings if you place it high enough. No reason to buy a new light right now.. If the soil has fungicide, then dampening off probably isn't the problem (because it is a fungal root disease). I am not sure what to tell you... Try some pepper or tomato seeds and see if...

    Half a bottle = Sensational times.

    Ahhh, I envy you. I've been in need of a tiny bottle for a while.. The last hits I got were diluted because they got wet.. What a bummer to barely feel anything at all.. Enjoy our stash while it lasts! Sounds fun

    My Seedlings are always dying!!

    i would keep the 400 watt bulb 3 feet from the seedlings until the second set of true leaves emerges... sounds like your seedlings are having a problem with "dampening off"...

    Taking clones from unhealthy mothers Help!

    Wowza! Your plants will be fine. I still do not understand at all how, after 6 months under a 1000watt bulb, these plants can be so short.. Were they pruned?

    First grow, how much longer till harvest?

    At what point do you abandon that philosophy, however? The problem has been getting worse for weeks. cannabis is a fast-feeding plant. The miracle grow nutrients are not the right ratios and strength for your plant. Adding some water soluble fertilizers would have helped. Your product would...

    High Ec

    Heat stress, Mag deficiency, or underwatering. Help please.

    Looks like it is OK on the nitrogen for now. Lay off the food until the second set of true leaves.. or keep it at 1/4 strength.... The heat is too much.. Also, are you measuring air temperature or leaf temperature? If your air is 90, what is the leaf temp? Too much, I bet..

    Best methods of quick dry??

    there is really not too much difference between oven, micro, and dehydrator. UNLESS you have a $400 dehydrator that has thermostat that actually works and has a knob. All of the Kmart and WalMart dehydrators create as much heat as a low oven. I know because I have hooked up thermometers inside...
