Does anyone know what this is? Please help... nothings stopping it

so my plants been pretty much completely healthy (at least on the surface) until about 2 and a half weeks ago, basically a week after it started flowering. first the bottom leaves started to yellow, then started to get a purple tint on them. Now many leaves at the bottom have fallen off and the yellowing/purple coloring is steadily moving up the plant and starting to get to my few remaining fan leaves. the ones that are about to die usually curl upwards and are dead within a day or 2. however all the buds themselves look healthy (not for long im guessing at this rate)

does anyone know anything that will help at all? I've been searching for days and trying to ask on many different forums but haven't received any input pretty much

here are pics...

ok there we go. i've tried flushing, checked the pH which came out to about 6.8, just tried foliar feeding the leaves a bit of molybdenum (which is the only deficiency i've seen that looks similar to this). maybe foliar feeding was a bad idea but i haven't gotten any helpful information from many of the forums ive posted on so far so I just had to do something to at least attempt prevent it

+rep is the least i can do for any help at all


thanks very much

Its hard to tell from the pictures but it looks like the first leaves that your plant grew are about dead. In my experiences this is pretty normal. You said that the yellowing of leaves has progressed up-wards and has gotten severe. What nuts are you using and in what quantity/frequency? You could have a deficiency or root problems. Some more info would be helpful.

my babies are losing almost all of their lower veg, all of my bud sites are doing great, but everything under is dying. they all turn light yellow and fall off. this is my first grow, i've fed them and fed them, nothing changes. but as long as the top and my bud site stay nice and healthy, I haven't really worried too much

The bottom shade leaves almost always turn yellow and fall off during the flowering process. I wouldn't worry about it as long as 95% of your plant is nice and green.

remember where your leaves feed from(the roots) almost appears to me that it mite be a root problem,,what is the nutes your giving them, are you sure you have a good enuf root source to support nutes ..plant doesnt look to be very old which means neither is the root system. which could be why flushing it didnt work ,i would try some root superthrive or some kinda root repair treatment..

ok thanks for the responses. yes its moving up the plant, the purplish leaves you see in those pics have already fallen off (didnt fall but they were brittle and snapped off very easy by hand) and now its up to the next leaf set and has almost killed it.

for nutes I am using a mix of organic worm casting tea and also started it on very diluted molasses a week ago but stopped in case it was making things worse (I doubt it was though... i'll probably start feeding it molasses again next watering). I only feed it the worm tea about once a week and i don't think i've ever overdone it. if anything its more likely im underdoing it with some sort of nutrient but hell if i know which one. the soil is Sunshine mix #4 with some dolomitic lime (pebbled) and bonemeal mixed in.


edit: also a few random fresh leaves at the top of the canopy have burnt tips?? its completely random maybe like 2 or 3 tips of a 5 bladed leaf, and it's only affecting like 2 sets of leaves out of the many that are coming out of the cola. i just thought that was kinda weird but thats the least of my problems atm

hey all I have some fresh pics for you... this one leaf is the most affected and distinct so hopefully one of u can notice a similarity to something you've had

FIRST PIC: sickest looking leaf on my plant, what is this??
SECOND PIC: the leaf part of the same set on the other side, looking a lot healthier but after the first 1 dies off the same thing will happen to it

bump, anyone?

what did you use to test your ph? hope it's not one of those soil probe testers, those things are worthless they always read about 6.5-7 ph no matter what you put it in!

if your ph truely is 6.8 my next guess would be that the tea you are feeding it isnt strong enough or well balanced enough to support the plants needs, i would get a proper store bought nutrient that is more calculated and balanced for plants. i dont have much if any experience using homemade teas, but im just thinkin that if i were to give one of my indoor plants thats 1-2 weeks into flower (as yours is) just mollases and worm castings, they probably would start lookin the way yours is? plants use alot more nutrients and energy during flower than veg. my 2 cents?

It's normal for bottom leaves to turn yellow and die, but those plants are literally starving to death. Whether it's a ph issue, root issue, or just not getting enough, that's what's wrong with it. Get some veg nutes with nitro and feed them good, I'll bet they perk up.

ya thats actually exactly what im using lol, a soil ph test probe. and ya thats exactly right, it basically comes out to 7 in most plants. then if I leave it in for a while it maybe moves a little to the left or right.

anyway... it crossed my mind i might not be using enough nutrients but i'm not sure exactly what kind to go with. plus I've heard changing or adding nutrients this late can be bad? I guess it can't rly fuck it up too much worse at this point.

thanks for your replies too

yeah, I've been reading that the yellowing was normal so I kinda ignored it but when this purpling curling shit started going down i knew something had to be up. do u think Miracle Gro Tomato feed 18-18-21 will do the trick or is that a big no?and I guess starting at half strength would be best to ease it in? If that's definitely no good, I have some other indoor plant food thats 1-2-1 and some other Miracle Gro stuff thats 20-30-20 i think. buying some would be a last resort as i'm on a bit of a tight budget

i was hoping worm tea would get me to harvest but i had a feeling this might happen around this time D:

haha, just as i suspected. those soil prode testers blow! i remember when i first got one like 10 yrs ago i was like 15 or 16, i thought all my prayers were answered. took me about an hour to find out the things about as good as stickin your finger in the dirt and takin a wild guess.

now that i know thats what you used im guessin your ph is too low causing nutrient lock-out. i'm not sure about the castings but i know for sure that mollases drops ph alot, i'll add a tbsp in a gallon of water thats 8+ph and it drops it down into the 5's ph! best advise i can really give is to get a solid ph tester, even if it just the drop kit from general hydro, then test the run off and get the ph where it needs to be and start feeding with that m-gro 20-30-20 or the 18-18-21 shouldnt make much difference wich one cause they are both practically general purpose only the 20-30-20 has more phosporus wich is needed in bloom cycle. also if your gonna get the drops i would get the ph up&down too so you can adjust your water/nutes accordingly

goodluck peace

Either nitrogen (unlikely if it is in flower, and the other leaves look fine) or phosphorus (most likely since more P is needed during flower.) Your pH is spot on at 6.8, so is should be able to get the nutes if they are their. Insofar as what nutes to use, I don't have any experience with organic nutes first hand, you would just want something with higher phosphorous and potassium. Good luck with the grow.

ok thanks. there might be some sort of pool pH test kit around here somewhere, I'll take a look if not i'll just pick up some strips or something. I'm gonna feed it with a bit of the 18-18-21 at about 1/2 strength just to give it a little something to live off of, and i'll keep it off the molasses for now as well. ill see how things turn out in the next few days. thanks again for all the help everyone

ok, this morning she's lookin not worse than last night, which is the case usually is so that's a good sign. i know I can't rly make the bad leaves become healthy again but hopefully i can stop the spread...

Can you recommend a good tester product?

Thanks
