looking for some help with yellowing, brown blotches (pics, details)

oh, also, i dont see any signs of any pest damage on the plants at all. any leaf with (what i assume is) "other" damage (deficiencies, or otherwise), has no damage or spots on the undersides of the leaves, no little white spots anywhere on the plant, no chew marks...i have seen a few gnats in the tent before, but im talking about seeing 5 or so in 7 weeks...and the little guys crawling around on the rim of the pot dont look grub like at all, theyre tear-drop shaped, and have legs...they move relatively quick.

the things that kills me is that i brought this on myself....as i said in my initial post, i had 40-50 other seedlings growing in there for 3-4 weeks, growing in a mix of miracle grow and compost from outside...yeah, i brought composted soil from outside into my nice clean controlled environment. i wont be making that mistake again.

so now im thinking about ladybugs, even though they might not eat root aphids, if thats what i got, but i know they eat many other pests, and dont harm your plants, so might be good to have em around anyways? anyone know a good place to get them? (like a national chain store that sells gardening supplies or somewhere?)

i think im also going to pick up a magnifier at radio shack today, so ill see if i can get some pics for you guys so i can nail down what in the hell they are, and i can go from there....
That sounds like the best plan. It's good to know what you're fighting so you can use the right tools. :)

Also the ladybugs love aphids. I'm not sure about root aphids, if they are different somehow, or if they are down in the roots the ladybugs won't be able to eat them. They won't hurt anything to have around though. You can probably get them at any big garden center in your area, a Home Depot, or maybe even a Wal-Mart if it has a garden section.

so i havent seen any bugs on the pot or soil since yesterday morning, but i gave some ladybugs a new home in my tent last night, just to be on the safe side....i also have two new resident super skunks that i rescued from a friend who unfortunately cant grow anymore. theyre in the middle, and the one on the right is a mazar seed i got from a friend, that grows like it smokes crack, but thats another story....

oh, and they look droopy because they just woke up, and i flushed them yesterday. they were perky as hell yesterday.

anyways, the NL (on the left) is looking better after flushing. a friend of mine that grows in FFOF told me that he gets bugs very similiar to the ones that i had, and he said they did no damage to his plant whatsoever, and guesses that they tend to be in FFOF in general. after doing more resarch, im wondering if they are predatory mites, they seem to fit the description i read....

i did manage to snap a pic of the bugs before my camera died (not a good one), but i cant find any more at all for now, so thats cool....

and then i have some clones working... used roottech, rockwool, humidity dome, and now a heat mat i borrowed....air temp is usually 80, humidity usually around 90% in the dome....its been 16 days, and im seeing actual roots inside the cubes on a couple cubes that i cracked open, and tiny nubs on the others...dont know why it seems to be taking so long (maybe im being impatient, i want to put the suckers in some soil, but i know not to yet)...but what im wondering about is the bumps around the rooting area....is that just pre-root callouses, something that occurs normally, or is is it possible that thats something fungal or otherwise negative?

Thanks for the link, looks like you may have already figured out your cloning questions, but if not . . .. :)

I use those pre-root callouses to kind of get an idea of which clones are going to root and work. If the stem swells up and gets those nodules, that's usually a good sign for that clone. If the stem stays the same size and gets no nodules they almost never root and just dry up.

I think those look like they would have worked had they not been ripped open, I have had to wait 3 weeks for roots to come out sometimes. My friend used those things you show in your pic and he was having problems getting clones to take so I had him switch to Rapid Rooter Plugs. They worked better for him, and they are what I use to start clones. It's not something that you need though, I think just a little more time and the roots would have started coming out.

i think theyll still pull through...i dont think cracking open a rockwool cube is anything detrimental, though i could be wrong, i dont think it would make a difference, they squish back together just fine....

as far as rockwool, im not a fan yet, i wouldnt mind trying some rapid rooters, they appear to be a bit more my style anyways....

You're probably right, I don't know why I was thinking you were trashing them after you opened the cubes. :oops: They should still be OK, it might even help give those roots a crack to come out of. :p

so the bugs seem to be gone, as are 90% of the ladybugs (apparently there was no food for them to eat, good sign i suppose, they died, about 40% got trapped in my reflector as well). but, im still having spots and blotches....after i flushed, i added molasses, and then nutes, and still more signs of this happening. anyone have any insight? your help is appreciated, and ill hook up the rep.

oh, and im now watering strictly with ph6.7-6.8 h2o. runoff is 6.6, i figure that is just fine....

seriously, no one has anything for me? ive read through quite a bit of info, trying to nail down if its a deficiency, or what, but i cant figure it out.

The yellowing on the leaves (interveinal chlorosis) is a sign of a Magnesium deficiency. Whether its due to a lack of nutrients or lock out is not important. Flush your planters with 3 times there capacity of reverse osmosis water properly pH'd then water with a mild nutrient solution (1/4 strength NPK only) and add 1 tsp per gallon of Magnesium Sulfate. Give it about 4-5 days on the mild nurient solution before slowly adding back in the other nutrients. Get you problem fixed before flowering or you will be sorry!

no, the pot has plenty of drainage. in fact, when i water, sometimes im concerned that there is too much runoff...

sounds like your overwatering if theres too much runoff ..which in turn, could lead to root rot and many other diseases and make plants look sad and droopy kinda like yours

Also remember that a Calcium/Magnesium issue will continue to show damage for a little bit even after you correct the problem, so if the bad leaves get a little worse it's nothing to worry about. Just make sure it doesn't get markedly worse or start affecting your new growth. If you followed Mr Bomb's advice then you're doing everything right to fix it.

bro i have the same problem with my plants
you have root maggots, im almost 100% sure
although you addressed the problem, it will take a week or two for all of em to die out, mostly worry for the lil guyz that feed on your plant's roots, these lil fuckers make your babies look the way they look in the picture above + they stop your plant's nutrient intake/
it sucks men
