If the Mg is getting locked out from the soil by lets say for example high salinity of the irrigation water it won't matter how much Mg rich nutrient you feed into the soil, if it's getting locked out it's unavailable to the plant for uptake despite the fact that there's plenty available in the soil.

Yeah, I was thinking about lockup issues, but I'm foiliar feeding too, and it's not helping

I am using distilled water bought from my local supermarket, I don't really know what the ph of it is, I'm guessing 7 or close to it. Feeding schedule is roughly about one cup of nute solution every couple of days, usually four days apart.

Okay firstly I think you're over-feeding it with the wrong kind of nutrients. Secondly, why does it need feeding if it's only been 2 1/2 weeks in that soil? What soil is it? Is it particularly bad soil? Why are you using distilled water instead of tap water?

What lights are you using and what ventilation method and where are you growing it, what are your lights on and off temperatures and humidity?

Overfeeding? Really? Hmm....it has been in the same soil for all five weeks, the soil is a custom blend....it's got scotts potting soil, miracle grow seed starting mix (I didn't use nutes the first 2 1/2 to 3 weeks) Organic potting soil, and peat moss. As far as distilled vs tap water, frankly I was under the impression that using distilled was better insomuchas that I wouldn't have to fiddle with ph, or worry about hard water or any of that nonsense.

Just out of curiosity what do you mean when you say 'wrong kind of nutrients'?

Oh yes, I am using cfls (yes I know, another asshole thinking they're gonna grow using those damn things) they're 75 watts and I've got five of them. Daytime temps are roughly 80 degrees F with a humidity level of 46%

I am growing in a closet, for space reasons. When the lights are on and I am home, the door is open and I keep a window open as well. At night and when I am not home I keep the door cracked. There is an oscillating fan blowing on the plants at all times (it's not part of the timer schedule).

I'm gonna guess at the moment and say night time temps would be about 70 Degrees. Does that seem too cold?

Go buy a bag, smoke, forget about this grow and start over.

LOL you think it's that fucked up eh?

I'm gonna try and see this one through, save my money and next time get me a HPS light. But then again the best lighting won't do a damn thing if I can't get my nutrient issues resolved.

Soils a custom blend? That's not really what I like to hear and it sounds like its time to repot it up into another or larger pot.

I'm loathe to say you're doing it all wrong, but you are! You should be potting up your plant in increments - starting out in a 4 inch pot, 2-3 weeks later potting up to a 6-8 inch pot and 2-3 weeks later potting up into a 12 inch pot, letting it root that out and put it into flowering. yours has been in the same pot for 5 1/2 weeks, its soil nutrient reserves are spent, it's roots are probably pot bound and you're getting all sorts of leaf problems - no surprise really eh?

Each time you pot the plant up into a fresh set of soil in a pot, it also gets a fresh set of nutrients to feed on and more room for the roots to grow. The only time you should be feeding your plant is sometime in the 3 week onwards of flowering, because it's in it's final pot and the nutrients in that final pot will be starting to diminish.

Your nutrients are wrong because the NPK values of them are unbalanced, they don't contain enough of the primary nutrients. At the levels you've been feeding them they've probably got a salt buildup as well.

My advice to you now is to repot the plant into a bigger pot with a fresh set of soil and start feeding it with straight forward plain tap water. Buy a cheap Ph kit and PH the tap water, and adjust accordingly. In the meantime, start looking for a bloom fertiliser with a balanced NPK ratio that isn't too high. Also, you need to get fresh co2 into yuor growspace, plants won't grow properly without a constant fresh supply of co2.

Absolutely right. Your CFL's are NOT the problem here using a HPS light would probably have made the situation even worse.

No, no surprise, but originally I had these guys in a big rubbermaid container, the pots you see them in now are the ones I moved them up to...I have read that you're only supposed to transport them one times at most...do you think repotting them once more would kill them?

Gotcha

I'll see what I can do...do you think I should veg for a little while longer to see if any of this helps?

Nah, it'll do them a world of good I reckon. I repot mine about 3 times before they go into flowering. Just be careful when you repot that you don't disturb the roots.

Sure, veg it for another couple of weeks, it's not ready for flowering yet anyway and you shouldn't really be putting a stressed plant into flowering. Repot it into fresh soil as I mentioned and feed it with the ph adjusted tap water and see how it responds.

We'll know a bit more about what it's problems are by watching it respond to the fresh soil and plain watering.
