Good grow going bad; need RIU to the rescue!!! (pics, history)

Hey, Folks...

Help a m'fer out here...

Here's the rundown: vegged 4 weeks, no issues 'cept radical growth under limited light range (shoulda vegged 3wks max), MG "3-month" soil, started adding Foxfarm GB (6-4-4) 3tsp/gal at 4 weeks every other watering; switched to TB (2-8-6) 3tsp/gal every other watering 2 weeks after flowers showed. 400W HPS 6-12" off the tops (never an issue whith that); got 4 plants now 4wks post 12/12 (44-48"); were budding nicely but now in a "stall". All show the symptoms of over-nuting to varied degrees -- the first photos are of the most-affected plants. The last two are leaves off the next-worst plant.. the fried one is in the middle of the plant, the next pic is the next leaf up (burned tips, but otherwise green and healthy).

Beginner's luck up to now.. fuck..!!

Here's the Q: I know they got overnuted; that much is obvious. But what to do? Flushing? I've seen a few reports that people have had even worse reactions after that tactic. Last thing I need is to make things worse. A very good grower on here suggested I go back to FF GB to restore a more balanced nutrient load but, man, that 2nd-last pic looks classic N-burn to me.. dunno about adding more..

Anyone pull a plant out of this sitch? That experience would really help.. I wonder how they can come out, since they basically have stopped producing leaves.

Here's the good news -- clipped and dried some of the lowest buds 'cause they had no hope 4' deep under the canopy, smoked 'em, and I'm fucked. Can't wait to see what this does when it's ripe..

Damn server cut me off 'fore I got to them.

Bump... need your input, folks.

Well, how 'bout if you had this problem, and you did X or Y and it killed them completely dead? That would help, too.

Dude, things don't look that bad. You plants are mostly green. Jut a few rust spots with one bad leaf. BTW yank it off, it is more than 50 percent gone. I honestly wouldn't sweat it. Looks like you might have over watered a little. I can't really tell but from the way they are drooping. Are they crisp? or feel moist? If you might have overwatered don't flush. Just wait 'til the next watering and DON'T feed. Just give them plain water. You have enough nutes in the soil. It doesn't look like you have nute lock up which is what flushing cures. All of my plants seem to stall for two weeks at 4 week point. Then in the last two weeks they really take off and put on some serious weight on the buds. You are only going to lose leaves from this point on anyway. Best of luck. Let me know how it goes. Looks like you have some nice buds tucked in there.

you burned them a little bit. Personally I would just water for a few times and then start feeding again at a lower dosage. As long as your problem doesn't continue to get worse I think you will be fine. I would say backing off a little on what you are giving them vs. changing nutrients or flushing mg soil would be the best tactic. They look droopy too, you might want to let the soil dry out good between waterings/feedings.

Lol.
It just minor tip burn.
Buds will eat the leaves anyway and if your lucky in the end all the leave will look fucked like that and youll be left with sticks of juicy buds

Schweet...thanks for the input. I haven't been feeding at all since this set in; been about 10 days since last feed.

They got overwatered a bit when I first switched to 12/12 -- failed to appreciate the cutback in usage with 6-less hours of light. But, this seemed to set in more when we had a hot day and the room temp shot up to 90+ (but, that only explains some curling; not the spots).

The leaves are still mostly soft -- I did discover a couple of crisp ones at the very bottom, where I wouldn't expect to maintain healthy growth (no light).

I am trying not to worry -- I've seen some fat-ass colas on here with really whacked leaf sets.. But, I've seen some, too, where the leaves looked like they could start work all over, if you know what I mean.

Well, that's what was freakin' me for awhile. I noticed this about a week ago, and it's been getting worse all along but... several full-strength feedings when they may have not needed ANY could take awhile to work through. Hopefully, this is as far as it goes.

I haven't fed since the first fried tips showed up about 10 days ago. I have been more diligent about letting them dry out since things started getting weird..

Seriously.. thanks, all -- you calmed me down for now.

can i add something to this? those burns on your tips are nothing, especially since you gave 3tsp/gal, i used tiger bloom and that is full strenth, she took all that up and shows a slight burnt tip? the other plants with the spots maybe a deficiencie and or PH issues, whats your Runoff PH?...IMO i think your having PH problems, i dont recall seeing you tell us what it is

Some strains are more susceptible to environmental conditions. I run 5 strains. The Arjan Ultra Haze I have is a pita always looks like it has something going wrong with it. While all the other plants in the room look fine. You just have to remember it is a weed it will grow despite what we do to it.

Yeah.. there's more than those little tips... got a few leaves that are pretty toasted.

I don't do a lot of pH measurement 'cause I don't have a good way to measure it. I know people bandy about over it, but all the cheap methods of measuring it are frankly bullshit. I used to be an analytical chemist.. if you spent less than $150 on your meter, you can maybe tell a 6.0 from a 7.0, but that's the best case.

I have done my soil pH with a cheap tablet test several times, incl. last week -- came out at 6.5-ish. But, I don't put a whole lotta stock in that. I'll try a runoff test next...

u should put stock in it for the simple reason theres some micro nutes that get locked out over 6.5, you can get a milwaukee for 30bucks on fleebay

Oh, I put a lot of stock in pH... just not the immediately available (and affordable) methods to measure it.

I'll check the Milwaukee... thanks.

They won't get locked out at 6.5 in soil...that's a good PH.

Your problem looks to me like a little heat stress and some nutrient burn. Nothing drastic though. Check your PH, but if anything your PH is going to be too low, not too high.

The nutes drop the PH pretty drastically and you should check the runoff to at least make sure you aren't at 4.5 ph (yes it happens).

Honestly doesn't look like a PH problem to me though, I think you're fine. Just water with plain water for a little bit and go back to 1/4 strength nutes and bring them back up incrementally.

Everyone here has given great advice, good looking 9 finger up until the burn. Nice first grow....good luck

Thanks, man... since posting, there's been some worsening on one plant that actually does look like some pH lockout pictures I've seen.

The 6.5 I got is from a cheap tablet test, so as much as I love the number, I'm suspect of the result. The girls have been on plain water for about 10 days now.. two others have "stabilized". There's one that didn't show anything 'cept a couple of very small burnt leaf tips.

I'll check runoff on the worst one when I get home today.

Gotta give credit where it's due..

Checked the pH of the runoff -- about a 4.0.. Yes, a 4.0.

So I added 1 tsp of lime per gallon of soil, watered it in, and collected some more runoff about a half-hour later and it already bumped it to about 5.5. So we'll see what happens from here.

So, +rep for you both...

thatnks for the rep bro, also watch your ferts, they advertise as "PH balanced" yet if you follow the lable on most brand names or even half strength the ph goes less than 5.0...my GH nutes at 2/3 strength give me PH in the 4's and i have great tap water at 7flat
