ok. I am 2 weeks into flower and my shortest plant is exhibiting some disturbing decay on lower fan leaves. problem has managed to only affect lower but I am worry it will spread to upper. I have 7 plants right now and this one is only one exhibiting these signs. lemme make it known that it is NOT a bug issue as I check every plant every day and have found not a single gnat or mite. temps are at 78 day and 70 night with good ventilation. ph stays in the 6's and the soil is soiless foxfarm mix of light warrior and ocean forest. I have gen hydroponics 3 pack fertilizer that I use at half to quarter strength. I think if it was over ferting then the rest of the plants would show signs but they are just as healthy as could be. All I can fathom is maybe overwatering or a calcium deficiency. but what the hell do I know? the first 2 pics are of affected leaves(1 just starting and 1 advanced) and the third is a mid level fan leaf that looks perfectly fine. all from the affected plant obviously. any opinions are greatly appreciated and rep for good suggestions as always. danke shern! :spew:

The holes actually kind of look like a possible bug problem.
I had a similar problem with a seedling and found a couple of tiny ants coming out of my soil during a watering, killed them by hand and the problem never spread. I don't know if this is the source of your problem but it's a thought.

Loosing some of the lower fan leaves is normal during flower. Mine look just like that (except the holes). Started as a nute problem for me. It doesn't see to affect the over all growth of mine so far. Take a look at my journal, there is a link in my sig.:peace:

it could be a few things.... how close are your lights to the leaves? wut kind of lighting system are you using? just because your temps are in the 70's(which is good) doesnt mean you have proper ventilation. are you running an intake and outtake fan? wut is the humidity? if its a defficiency problem it could be magnesium defficiency. if the leaves feel crispy and dry then its most likely a humidity problem. if its humidity the cell tissue inside the leaves will break down and die off. try placing a couple cereal bowls filled with properly pH balanced water(6.3 - 6.8) and once the leaves get to humid they will evaporate the water from the cereal bowls into their leaves. wont fix the burnt leaves but will prevent the problem from persisting farther.

the holes were spots where it was yellow a few days ago and as it got bigger the spots became small holes, small at first, and they have gotten bigger as the plant has grown

I'd flush the plant in question, then hit it w/full bloom ferts and something like Alaskan Fish 5-1-1, which'll supply enough N thru week 5-6.
This halted my EARLY yellowing (after years of trying)

2 weeks into flower you probably shouldn't be losing fan leaves quite yet. Have you checked your soil pH, or runoff pH, or the pH of your water/nutes? You're pH could be just a little bit off and locking out one or two nutrients, causing your deficiency.

Mystik, I had a minor ant infestation of one of my plants as well...had no idea they were even there until I started watering and they headed for the hills (or the surface of my soil). I killed them by hand as well, but also found that ground cinnamon works wonders on those little buggers. I just layered it around the top of my soil and gave some water to help work it down in there. Covered that with a layer of sand and those suckers are GONE!

Were would you place the bowl? on the floor around the pots? in the pot below the plant? I didn't think that it was an enviroment problem with mine since the humidity is around 60 most of the time, and its not all of them. Could there be to much air moving and drying them out?:peace:

plants are 24 inches from a 250w hps and have an intake and exhaust. humidity is at 65 % right this minute but never strays but 10-15% from that. they do feel crispy though. but only the affected ones. will try the water in bowl thing though. I doubt it will raise humidity to mold levels so whats the harm right? anyone else?

that means it must be either nute or light burn imo. did you foliar feed at all? it looks like it could be bugs at first though so still go and look on the bottom of the leaves, if u see some black speck looking things it is bugs most likely. but mine did the same thing and it was from foliar feeding water staying on the leaf and acting as a magnifying glass (like with ants lol) happened 2 times b4 i learned about it and once i started adding a drip of dish soap to my foliar mix as a wetting agent and it never showed it again.
