leaves dieing, yellow, veg

[medical/420]

ok my leaves are yellowing out and dyeing on the bottoms of my plants, what could cause this, some are in Roots organic super soil, some are in used happy frog super soil and some are in just roots organic or happy frog. it seems to be adfecting all the plants in veg,

Could i have a BUG in my root zone?
could over watering cause this?
since the yellowing started 1 mounth ago i have been trying to get them to green up, with humus teas, organicare pure pro grow, and other stuff, new growths are amazing but my older leafs are dyeing off by the day.

dry them out, imo

yeah i was thinking that, The leafs wear turning yellow, so i was trying to feed them, in order to feed them they gotta have water, so i turned a small problem into a Big problem. I am going to really lighten up on the watering, I think i got them enough food for a minute.

SO OVER WATERING CAN CAUSE LEAFS TO YELLOW AND DIE? (I really messes my knee up and could not walk for a month or so, and getting to my Medical garden became a HUGE pain in the ass, so when i went in to water i guess I made SURE they had Plenty of water (too much water) so i would not have to go in there everyday. and I think that started it, than i was trying to feed them to get them healty again, and it anit getting any better.

I want the best weed possiable, and i know with plants looking looking like this, they aren't ready to produce high grade meds.

Never heard of that,most times over watering a plant it will get all droopy looking just like when they need a drink,have some outside thought they were getting plenty of rain, but checked them and were all droopy gave some water and that afternoon they were fine.

Is this indoors or out? You have them in containers I am assuming due to the various kinds of soil you're using? A couple good photos would probably help us see what is going on.

Did you add dolomite lime to you soils before planting in them? You can feed all you want but if your soil pH is way out of whack it isn't going to make a difference (although soil is more forgiving in this respect).

Particularly if you're indoors, the lower growth could just be dying off due to lack of light.

The leafs start to get yellow, than die, than i puck them, and new ones yellow, than die, puck repeat. I like my plants to do this at the END of flower not MID veg.

ok theres your problem right there, stop plucking immediately. you are stressing your plants out everytime you amputate a fan leaf, and all that occurs as far as your yellowing problem goes is the "sickness" simply goes right to the next set of leaves. Let the plants handle yellowing of lower leaves by itself, it will actually segregate the problem to those sets only if you leave them on the plant.

You never want to leave dead plant materal on a plant, I do know this much, dead leaves give pest places to hide, I dont pluck them when they are alive, but I allways clean out all the dead stuff. LOOK CLOSELY at the last 2 pics, see all the DEAD leafs?

is it possible they r root bound?? wot size pots r they in???

IMO nothing really that bad just watch the watering one leaf does look like it was droopy and died as long as the new growth is fine woundnt worry unless problem gets worse.
My plants lose some leaves during final stage of flower but thats N def.And expected.

ok bud, where did you get that "rule"? go ahead and pluck all your dead fan leaves off and see what happens. Cannabis does that for you, without passing the problem onto the next set. Pests "hiding" on a fan leaf right in plain sight? Not likely, and what pests are you talking about? All you are doing is slowing down your harvest.

If the leaf is totally dead and necrotic it will fall off by itself. That's cannabis' system to deal with sickness. And you shouldnt have that much dead material anyway. Plucking leaves every two weeks or more sends the plant into SHOCK, slows growth, and is NOT healthy, basically tells the auxins to go on lunch break. We grow in organic soil mixes, and always have the first set of fan leaves, and sometimes the second turn yellow and ugly by the end of the grow, so we leave them on until they fall off. Means nothing of any consequence, yields and quality have always been unaffected. I would add that leaving the fallen fan leaves laying IN your soil IS a great way to get some food to any pests lurking in your root zone. So that would be bad. Clipping off fan leaves every time they turn yellow is bad growcraft. I know from making the same mistake for a long time. Cheers.

I do see that you are very near harvest as well, so really leaving on the fan leaves at this point is inconsequential I suppose, it's kinda late for pruning water leafs to affect the overall health. And since you are in flower, I can understand keeping it clean from pests and everything. I hope I made at least a little sense though, constantly clipping fan leaves off is a no no for us.

I am not Flowering them yet, I need to get them healtyer before They gointo the bud room. I know what you are saying with Dont puck the leaves, I guess I should of said I Clean up all the dead leaves that get stuck in the mass of other growth. my camrea sucks but if you inlarge the pic, and look CLOSELY you can see all the DEAD leaves that are only held on by other growth. this happens to me at the end of flower not mid veg. I dont know what to do, i have plants in 3 gallon - 12 gallon soil contaners. I guess I am going to chop them down and just Start over, 12 plants is plenty when stuff works out right, but when stuff goes bad, you just gotta suck it up, chop them down and start over/

Ok, i figured my problem out. the only thing all the plants have in common, is I started useing Un-PH'ed Well water, I usally use Rain water, but as you all know It anit been raining much in the USA. so I used well water. It has alot of minarals in it. and i think the Ph was around 7 when i checked it 3 years ago.I think with a Organic soil you want to water with Acidic water and let the Dolomite lime Rasie the PH. I bought a few clones to replace those plants, Jack herer, chocolope, jilly bean, qurkle, Flo, I am going to try to clone my Bubbakush and ace of spades and keep them around. One SMALL short cut and it all goes down the drain I didn't FAIL , i just leaned what NOT to do. LOL live and learn i guess, I am ready to grow some dank now. Got my new bacth of super soil cooking, New plants rooting, now i just need a new water soure or some rain..What do you think about a stagnet pond water, can i bubble it for a few days than use it. I dont have money for a R/O setup, exseshally since my little mistack costed over $500. 3 mounths of power, 10 x 10gallon contaners full of super soil at almost $40 each......... i better stop adding because it is allready over $500 not inculding the bottled nutes i tryed to save them with and my time.

I think you could be right about it being a PH issue, but if your well water is 7 it's not the problem. Dolomite will stabilize the soil to 7...You should test the runoff after watering to get your ph. Or grab a soil ph monitor...theyre like 19$. I'm not convinced it's ph though. The soil your playing with is probably hot as fuck..and burning your plants. btw I use spring water that feeds a pond...and I have good results

 

[stoned cockatoo]

Aslong as your letting the pots dry out your not overwatering

 

[grandaddydank]

ok cool I wasnt trying to talk down to you btw, may have sounded harsh. This happens to you with different strains as well? The pics arent too clear no offense, but from what I can see looks like one of many things, or many combis -

is that a scrog? or irrigation system? (eyes arent what they used to be)

adequate ventilation?

complete fertilizer? (balanced - 1-1-1 or alt) micronutrients?

water? we like to use (cleanish) tap early in veg, then move to R/O in flower

I feel your pain, any losses feel like a kick in the gut nowadays. There has to be a way of saving this grow, I would back off for a day or two and totally reacess the situation, obviously the plants arent totally necrotic or in actual danger of keeling over so you can rescue them I would think. Maybe cut some clones and put them in tap water to root, I have had to harvest entire plants for clones when they got too sick to save. Good Luck buddy.

there has to be some organic health food store around you right? we just go bottle it up at the store. yea pH sounds like it, try dropping whatever water you use to 6.2 to unlock if its too high, and feed them some micronutes (Iron Sulfur Manganese Magnesium Calcium Zinc Boron)

I wouldn't chop them all down, I think that's an over-reaction. It's the bottom growth that is most affected.

Sometimes we have problems, and they can be just minor little issues but we turn them into even bigger issues by over-reacting or making rash decisions. (For example, feeding more to a plant that is over-nuted because we think maybe it has a deficiency.)

So your plants are in 3 - 12 gal. containers, there is just one plant in each container right? 12 gallons seems quite large for an indoor grow. The biggest I use is 5 gallons for plants over 3 feet. Are the plants in the smaller containers equally affected as the ones in the largest containers?

Ok, i figured my problem out. the only thing all the plants have in common, is I started useing Un-PH'ed Well water, I usally use Rain water, but as you all know It anit been raining much in the USA. so I used well water. It has alot of minarals in it. and i think the Ph was around 7 when i checked it 3 years ago.I think with a Organic soil you want to water with Acidic water and let the Dolomite lime Rasie the PH.

The pH of the water you put in really shouldn't matter even\if you have dolomite, as long as it isn't too high or above 7. The dolomite helps neutralize acidity, if the water is neutral already it wouldn't affect pH either way. If the well water contains high amounts of dissolved solids like you say, however, it may also have significant amounts of carbonates which will give it a pH above 7. The pH of the well water definitely might have changed in 3 years time so I would check it again. It could be above 7.5 and that could pose a problem. You could check that and the run-off when you water just to see where it is at and possibly rule pH out as an issue.

Although the photos you provided aren't the best and they're kind of blurry, in this one here some of the leaves look like they might be expressing a magnesium deficiency.

You might try a light foliar spray with epsom salts and\or a good micro-nutrient formula (such as Earth Juice Microblast).
