Great thread! I learned a lot from it. I've been very confused about nutrients, but now it is all starting to become clear. I've bookmarked this and will use it as a reference just in case my plants start lookin sick.

yes and no, some strains just have a darker red stem, its just part of the strain, thats why i dont mention it or try to go by it.

add more nitrogen, and add some micro nutes. make sure pH is 6.8, and you should be fine. I dont think its a mag deficiency, they are still vegging, and have a long way to go before micro nute deficiencies really start to show. you can add in some micro nutes, but the real issue is nitrogen
and if your indoors, you should top them, and get more yield. or you need to lower your lights, you got a LOT of stretch going on there
another tip would be to start adding in some P and K, small amounts during veg really help prevent a lot of issues.

Thankx man ... i have added a 1.1.1 npk solution with added micro nutrients .. the ph is ideal 6.5 ---- i have a lot of stretching but i am worried about the temp that is the reason the light is almost a 1 1/2 feet away from the plants , it gets really hot in he place iam growing usual temp is around 30 to 35 C but often reaches 40 C... its a 400w mh. . the plants are in their 8th week of vegging from seed . i am really not sure about topping cuz some sites say it stuns the growth. but would give it a try on my clones . any other good advice would be appreciated. and thanks a lot....

yea a foot and a half away is a pretty big distance, but yea i agree, thats still better then heat. I too have heat issues, i have to have my AC on cranking in the summers here (reaches 45C / 110F easily, for a few months). one trick for lowering heat is to mist them with distilled water, turn off the HID lamps, spray them down, wait 15 min, then turn them all back on.
Cloning/topping does stunt growth, for 2 or 3 days, the plant will focus on healing the cut, and figuring out the new way of growing, but its worth it. I top them now all the time, and unless i start growing outside, i plan to keep doing so. besides, thats how ya get clones, and if ya get a strain you really like, you dont wanna flower it and be left empty handed. Clones make sure you get the same strain again and again. Also, taking the clone might stunt the growth of the mom for a few days, sure, but replanting the seed and waiting 3 weeks for it to be the size of the clone you would have taken.... is 3 weeks of more growing, and less smoking.

I've been trying to find a little info, do you have any tips, know of any easy ways to adjust you pH in your soil? All i'v found was info about using lime and sulfur to adjust your pH. but it doesn't really say anything about whether i nee pure lime and sulfur or if i can use something with lime or sulfur in it. I'm sure i'm not the first person to ask this question, but any help would be great. thx.

Hey, so theres a lot of ways to regulate pH
the idea is that you want it close to 6.5 all the time. Lime is good (comes as a powder, or little balls), becuase its a buffer, same as sulfur. What that means is that its pH is strong. No, i dont mean strong like very acidic, or very alkaline, but strong as in fixed.
Lemons for example, are the opposite. Lemons are very acidic, but with a gallon of water, the resulting pH is very close to 7.0 A buffer, when added to other stuff, forces the other stuff to change over to its´ pH, instead of them mixing, and balancing each other out, or in the case of lemons, doing nothing really.
So what do ya do? get some lime, and add it in when you mix up your soil, whatever the directions are on the bag, those are probably fine. it doesnt take much. I also take the Ph of my nutrients, so i know how acidic/alkaline each is, and how it will react.
The last step i take to ensure a good pH is i go to the petstore, and find some liquid buffer. The bottle that i find is for tropical fish, to keep the fish tanks at 6.5 pH. I use maybe 1 cap ful per 5L of nutrient solution, and water the plants with that. Ive never had pH fluctuate more then .1 or .2 since ive used this liquid. It rocks, and its only 5 or 10 bucks
I do stop adding everything not organic a week or 2 prior to harvest, to ensure a nice smooth taste. It really does make a difference. weed thats not properly flushed out is harsh, and after smoking a tree of it, youll want some throat drops. Best to stop a week or 2 before and prevent that. During those last 2 weeks, i try to stick to just plain water, some organic sugars, and if needed for pH, a teaspoon of lemon juice per 5 liters is usually enough to bring it down just a few tenths under 7.0
Make it easier for yourself, big pots, fresh dirt, and get that bottle of liquid ph buffer.

wow, thx dude, that helps alot. there's a topical fish store down the street, i'll stop on teh way home from work tomorrow and pick some up.
Here's a pick of my next grow. I'm posting it because of your comment about big pots. that last batch i did, i used smaller ones, thinking there were going to be good. but one day found my plants tipped over. so on theses one i bought these two planters, they are much heavy and about 50% larger then the ones i used before. you think these are big enough?
Edit: if you were wondering about the plants. they are Mango Kush, and 2 weeks from cutting. they've been in soil for a week, and have grown 3 inches.

roots need more oxygen
Why is there no pictures of what it would look like with a copper deficiency? I am wondering because I have a couple plants that seem to have leaves that are twisting. I have 24 plants and only a few of them are twisting. Everything is exactly the same for every plant so Im not sure why only a couple are doing it. I noticed it say that copper deficiency will have twisting.
