You are right sir, that's the inside of a DR100, a mighty mighty fine investment if you asked me. I'd love to have the space to house a DR150 and this DR100 and use the 100 to veg and the 150 to flower. one day, one day....

luckily I already have a fan speed controller that I don't have hooked up right now that I can attach it to my light/exhaust blower and dial it back a tad to see if it doesn't help... i should still be able to suck all the stink out with the cfm turned down a bit..
It could also be windburn. The fan pointing at the plant makes the leaves to transpire too quick(?). You will see random "burn" marks on affected leaves. My girl showed similar leaf damage as yours so I removed the fan completely. Well I'm not really sure if the fan was the problem yet since it's only gone 2 days.
Does the leaf feel dry and crisp?
The negative pressure will give sufficient airflow imo since it's sucking air from the buttom. Excessive negative pressure could affect the plant negative as cerberus says. PC fans are cheap and can even out the pressure.
Well it's up to you to try without a fan pointing at the plant. It doesn't hurt to try.

I don't see how it could be windburn, thanks for the input though, there are two fans in the tent, one has been there all along and the other I added a few weeks in, but neither one is hurting the plant. The only fan pointed directly at the plant is a 6'' air king that's hanging in one corner, it's just helping circulate air, it's not even blowing that hard. The 16'' oscillating fan I put in there after the fact is not even pointing directly at the plant, it's aimed at the side wall and is helping suck air from the vent coming from the AC, it's moving around a lot of air in the tent but it's not blowing right at the plant, as I said. Wind burn would take more fans or more direct air.
Damn man, looks like the same issue as im having and it isnt improving at all. How they looking now? Long to go until they finish? After you flushed, how much and how many days after did you feed? I know it may have been asked(ive been reading the whole thread in portions and forgot some bits) but are the plants root-bound at all? How big are the pots? I feel for you, its so frustrating when you have put so much time/care and then they throw up a very hard to diagnose problem.

Add Epsom salt to your nutes tsp. per gallon it's better than Cal-mag. It's 100% magnesium.

Now they are still slowly getting worse... they won't be finished for about 6 more weeks earliest, I fed 1/8 strength three days after I flushed when the dirt became ready for the next watering. Plant is in a 5 gallon nursery pot, I don't know about root bound, but the plant did grow large, i can only imagine whats under the dirt, I can't wait to see what the root ball looks like on this girl.

I have a bag sitting right here if it will help. I fed her with strait Epson salt just before I flushed her, I could touch up one of the next waterings, I think the next one is Sunday and is a feed, but I'm not sure what I'm going to do yet, feed big in case it's a deficiency (or lack of food), or feed light because it's a burn (I recently flushed so could that even be it still?). since flush i fed once at 1/4 strength and then again on the third watering at 1/2 strength. Could that much food not be getting used and is still in the dirt locking out other minerals? This plant is right in the middle of flowering I would figure it would be burning up food the fastest in it's entire life.
for mine im going to try a massive feed, i figured the same as you that it would be needing a lot more food then anyother period in its growth and if youve flushed it will flush a lot of the built up nutrients in your soil, so now the soil will probably have nothing in it the plant can use other than what you feed it.
it cant, you are using far tooo little nutes for it to be burning, unless there is loads of "built in" nutes in the soil

Plants medium is mix of 60% Fox Farms Oceans Forrest, then about 20% Fox Farms Happy Frog, and about 20% Extra chunky perilite... most of that going in the very bottom to make a great layer for drainage out of the pot. All this is mixed in a 5 gallon nursery pot.

I guess I will continue the way I was doing it and feed at half strength and just be sure to give a more flushing watering when I do the 'every other' watering.... i'm afraid, as we discussed earlier, that the initial issue stemmed from me not flushing out the buildup of salts/nutes in the pot, creating lockout and then deficiency after flushing... You've reasoned though this with me more than anyone else Moash, I am very appreciative of your work class assistance.

anytime man
how long have u been feeding half strength?

Well, you remember I just flushed recently, after that I waited three days till it was time to water again and gave the gal 1/4 strength nutes, maybe even slightly less then that.... very week. After I did that I waited 3 days and gave strait water, then 3 more days and gave strait water again, I couldn't wait another 3 days to feed again because she was looking so in need, so I feed after waiting just two more days a mixture that was at about half strength... I waited 3 days then watered just yesterday. (with a touch of cal-mag and molasses)
It's been taking about 3 days for the plant to show signs of being thirsty, so that's why I water every 3 days. Next Sunday I guess I'm going back to my water/feed/water/feed schedule instead of sticking with the water/water/feed/water/water/feed schedule that Cowboy logic suggested, I think the plant has spoken and is telling me to do something a little different, I think Cowboy's logic would suggest that I follow what the plant is telling me and what it wants as apposed to what he thought it needed weeks ago from his perspective.... like you guys said, just look at it and it will tell me it's story. Well it's talking, I just hope I'm hearing and interpreting it correctly. Anyone else hear anything any differently?

fyi...that is a correct way to feed ur plants and should normally be taken
i suggested the feed,water,feed cycle because ur plant is hungry and there was nothing in the soil,after it levels out go back to the other cycle
and if u dont see improvements,dont be afraid to step it up a notch.....ur plant should be able to take more than 1/2 strength
just dont overdo it or u will have the same problem
