leaf problem

2 plants under a 430,,same strain,,one has been discoloured for a while,,one is green

2 plants under 600,,one is green,,one is doing the same thing ,,browning and curling

all are the same strain,,

right now plants are 77 days old,,flowering has just begun 5th week today

under the 430 I have noticed,,one container always leaks some water,,and one doesn't,,could be the way I filled the container,,not sure

also,,because this cab stays so cool,,I have had the light up to 8 inches away,,but like I said,,the plant right beside it hasn't minded,,and,,,most of this problem exsists only in the canopy ,,or the most leaves seeing the light,,,underneath each of the problemmed plants is much greener looking

so here is a pic of a leaf,,that many leaves look like,,some are curled up and dead,,,also,,under each light,,one plant has been showing colored pistils for far longer than the other one,,under each light,,if you need more pics,,see some of the last pages of my thread New Beginning,,under Grow Journals,,3 weeks to go,,are they just getting old,,or is there a problem,,appreciate any help,,thxs in advance

Keep on Growin

from what I've read, that looks like spider mites. google (image) spider mites cannabis or search in RIU and you'll see pics.

Hey Hole, I don't think it is spider mites, cause you would have them on all the plants in that close vicinity. Are the ones doing this, the ones that leak? Could be a nute deficiency or something.

thxs Chiceh,,under the 430,,one leaks,,and the one that looks more done than the other,,doesn't,,but under the 600,,the one that does leak out is the bad looking one,,they do only have 3 weeks to go,,and if you look back arouind page ,,,errrrr,,,,,way earlier,,you can see they went through this same kinda burn,,they were seeds from a last time outdoor grown plant,,so I don't know if this matters,,the last time they looked l;ike this,,they needed nutes,,<--growing in Pro-Mix,,soiless medium,,it's hard for me to figure out,,cuz in both cases under each light,,one looks about right,,and one doesn't,,really appreciate this Chiclet..

If they have 3 weeks left to go, will you be flushing next week? How do the buds look? I wouldn't worry this close to the end as long as the buds are good and getting fat, could be just the way this strain goes at the end. My last harvest, lots of the leaves turned brown and fell off. The plant just focuses on the buds at the end.

I think last time this plant was "Commecially" grown,,,and didn't look that great in the bag,,was very green and weedy looking,,,,but was very good still,,,didn't have as much crystal as I do,,but in the bag,,no leaves look fukked,,I am looking in my closet now,,and one plant same strain looks fukkin eh,,and one looks three weeks older,,maybe cuz it's unknown strain,,who knows what I got,,if you need some better pics,,I will take them,,of my closet right now,,where one looks like it's almost done,,and one is green as hell,,and pistil white,,side by side

I don't know what to think,,here are a few better pics,,this is one plant under the cool tube,,the other is fine,,and just starting to show a few yellowed leaves,,but they have 3 weeks or less of flowering left,,anyway,,the HoLE canopy of this plant looks bad,,but if you look right under the canopy,,3rd pic,,it looks mint,,even though the cool tube is really cool,,could just the light being to close be just to bright on them,,and fried them,,any more thoughts would be appreciated

potassium toxicity is what this looks like to me.

do some research Marijuana Plant Abuse

Hard to tell under the cool tube. Though harvest being this close I would flush and if they keep heading down hill it maybe time to harvest. You have some nice buds so another week or so and if problem persist slowly start taking them out. Then I would rethink my nutes and additives for next grow to avoid this problem again. Good luck and smoke.

looks like spider mites dude ?
