OregonsDank messes up :(

Magnesium (Mg)
Magnesium is a component of the chlorophyll molecule and serves as a cofactor in most enzymes.
Magnesium (Mg) deficiency:
Magnesium deficiency will exhibit a yellowing (which may turn brown) and interveinal chlorosis beginning in the older leaves. The older leaves will be the first to develop interveinal chlorosis. Starting at leaf margin or tip and progressing inward between the veins. Notice how the veins remain somewhat green though as can be seen in figure 15.
Notice how in figure 16 and 17 the leaves curl upwards like they're praying? They're praying for Mg! The tips may also twist.
This can be quickly resolved by watering with 1 tablespoon Epsom salts/gallon of water. Until you can correct nutrient lockout, try foliar feeding. That way the plants get all the nitrogen and Mg they need. The plants can be foliar feed at ½ teaspoon/quart of Epsom salts (first powdered and dissolved in some hot water). When mixing up soil, use 2 teaspoon dolomite lime per gallon of soil.
If the starting water is above 200 ppm, that is pretty hard water, that will lock out mg with all of the calcium in the water. Either add a 1/4 teaspoon per gallon of epsom salts or lime (both will effectively reduce the lockout or invest into a reverse osmosis water filter.
Mg can get locked-up by too much Ca, Cl or ammonium nitrogen. Don't overdo Mg or you'll lock up other nutrients.

Nitrogen Deficiencies:
Plants will exhibit lack of vigor, slow growth and will be weak and stunted. Quality and yield will be significantly reduced. Older leaves become yellow (chlorotic) from lack of chlorophyll. Deficient plants will exhibit uniform light green to yellow on older leaves, these leaves may die and drop. Leaf margins will not curled up noticeably. Chlorosis will eventually spread throughout the plant. Stems, petioles and lower leaf surfaces may turn purple.

one or the other, i was thinking Mg cause it looked like the older leaves first, but on second look, the whole plant looks kinda pale. Look at my plant in the picture I posted, see how dark green it is? Feed them nitrogen and they'll turn like that. Mine actually may be close to too much nitrogen, cause how dark they are, but they haven't been showing signs of nutrient burn and are still growing fast. We took a break from feeding though.

i dont think it is Mg as i cant really see yellowing with green veins. and the burns arn't in the intervenual regions.

you know what it ;might be a disease. as it looks like the dead parts are causing the yellowing. Not yellowing causing the dead.

as there are burns surrounded with green. hmmm.

as well the dead spots are not uniform and dont follow a pattern. Which i would exspect from a def. hmmm very difficult.

question: does this disorder start on the lower leafs and work its way up. if so that would promote the idea of a mobile nute problem.

as the growth tips look fine i wouldn't think it's a immobile problem.

you need the pro's

Ty very much for your time Harris7.


I am very sure my plants are to say the least... starving. My NL is almost 18 inches tall, 6 or 8 over the rest, so I feel I need to bud soon.. Would you guys, or you harris, wait a week or 2 till I fix them before budding, or would you bud now so I can get healthy clones and new plants in sooner.

Here are some pictures of them with a better camera.

Btw, The plant in front center isnt leaning at all, I tied it down tonight, Very strong so far holds it self up very well, but some of the tops do seem to be curling?

Anyone have any suggestions for this comment?

I really need help figuring out whether or not to bud now or wait till I make them happier?

first off, you dont want to clone in flowering because you will need to reveg the clones and stress your plants when they need to produce. you can apply some lst training and tie down the main stock of the NL to get it close to the same size.for when to flower, wait a week or two after you clone and your plants are out of shock. the healthier the plant is in flowering the more energy it can use to produce the sweet collie bud.

Yeah man, Nitrogen deficiency is my final answer, especially after that last pic of them all under that light, they definitely look like they're a little pale. I'd go ahead and try and make them happy, but I'm not sure. The thing is, they don't really need much nitrogen during flowering, but what nitrogen they do need they use up from the leaves, turning them yellow. I don't know for sure man, but i'd think it would be best to get them stocked up on N before swapping over. Other than that one with the spots though, they all are looking great, just a little hungry.

I can't wait to see bud shots of these things.


But yeah, as far as that tall NL, LST'ing is the way to go. Don't be scared to get physical on them bitches with some string, they'll thank you later. Check out my log man, ever since we started tying, I've noticed exponentially better growth simply because of the better light distribution. http://boards.cannabis.com/showthread.php?t=90199
