Thanks kaleo

had a hard time finding what i was looking for but im SURE ive read about it before

im leaning towards a micro nutrient disorder or some kind of chlorosis, but im finding myself at a loss

No probs man thanks for your help



Anybody else got any ideas wat it is

Magnesium

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




I got this from https://www.rollitup.org/marijuana-plant-problems/157345-have-plant-problem-check-here.html
I had little rusty looking spots like that when the plants were young. I added CalMag to my feed and it stopped it in its tracks. Dont expect for those leaes to heal but it shouldnt spread to any other leaves. Thats about the best i can do without bein there and experimenting
Hope this helps and good luck

tips culing up ive read could need more nute but i also had some spots like that before and i pretty much figured out it was my light too close. Im still pretty new at this so i dont know everything yet so im not sayin thats what it is just tryin to give some ideas

ive also read you should never add salt is this true?

maybe not table salt, but epsom salt is a good thing

also just a note that you may not actually be deficient in Mg but your ph may be causing a lockout. It usually good to have a small fluctuation of ph to help nutes that are absorbed at different ph's get in there better, just not a big jump no more than .5 a day in soil

here is a chart to show you what ph absorbs what nutrients best and then you have to try to find your plants happy medium

also like i said this is only a reference for ideas. you kinda have to play with it until you find the problem but at least its a start. i guess i just get lucky an usually get the problems fixed first try i dunno.

thats a great chart man, something i hadnt thought of ever.

+rep for the food for thought

I just checked my ph and its at about 6.9 but i will get some epsom salts tomorrow and see
