Tortured Plants!!

[grassfarmer]

I'm sad to admit that my poor plan\ts have been through a lot of things lately and I'mnot sure what to do about it, or what the real problem is.

While finishing building the flowering room my rooted ak clones stayed in keg cups for about a month. due to me neglecting them, the temperature in the veg closet under a couple of fluros was too low, in the 60's. Eventually they started to yellow, older leaves first, then spreading through the plant. I am feeding most of the advanced line.

After setting up my sealed room(3k) and transplanting, I noticed that my ppm3 was not shutting off my co2 burner at the setpoint. While trying to figure that problem out the plants were subject to extremely high co2 levels for a few short periods. over 5000 on one occasion.

After deciding to return the meter, I put the burner on a timer for 15 mins every 6 hours. after a few days of that the plants look horrible. I plugged the controller back in and realized that during those 15 minutes the co2 was going well over 2500. I'm hoping that this is the source of my problem, and I have changed to manually turning on the burner for 4mins twice a day, just wondering if this has been seen before, and what to do about it. I just want my plants to start looking healthy before I start flowering.

Thanks to anyone who read all of that, and please help sorry about the pics.

Shut off the CO2 and figure out how to grow good plants before you get into advanced techniques (seriously, not trying to be flip)....you can probably chuck most of those AN products too and save a whack of money and grow pot just as good, if not better.

You will need to post pix and fill out the form in the sick plants sticky before anyone can help you more.

Cold temps inhibit the uptake of Nitrogen and other nutrients, most likely causing that leaf yellowing you talk about.

your advice is good, but I have (believe it or not) had plenty of succesfull grows before, unfortunately this one has been plagued with problems mostly due to bad scheduling, and only being able to visit the grow once, maybe twice a week, even during construction. the person who lives at the grow is physically handicapped and that puts a lot of pressure on me, a hate trying to catch the room up to the plants. the construction is done now, environment conditions are great, but I think the plants enountered some toxic co2 levels. I have a new controller on the way, to remedy that just trying to confirm this problem.














keep the ridicule coming because I kind of deserve it.

Sounds like you know what the problems are, what to do, you just need to do it and get those healthy plants you are looking for....good luck. They don't look too bad at all. Mostly looks like N def. If you aren't sure about your feeding, then post it up and we'll look at it. If you are, then it is probably just those low temps that caused the yellowing.

Heh heh, build the room first...seems a lesson to learn the hard way (myself included, many moons ago).

thanks for the words, my feeding is just under 700ppm, and definetely well balanced. I guess I should clarify, that although they were a few slightly yellow plants under the fluro with low temps, once I put them under the big lights (3-4 ft away) and transplanted into 3gal pots they got way worse realy quick. this is also when the co2 situation got out of hand.

heres 2 questions in case anyone reads this

1.) Do toxic co2 levels cause reactions like this? (signs of almost every nute def)
2.) What do I do if anything to remedy this fuck up?
3.) could it be something I havent thought of?

My nutrient strength is not very aggressive for there age, ph meter is calibrated corretly, room temps are constant 77. (within 2 degrees either way)

Let me know if you think they could be reacting from one of these more than the other.

-way too long in keg cups
-low temps in cups under fluros
-extremely high co2 levels

Input appreciated

1)No, there isn't a toxic CO2 level you could create with the info you provided.
2)The plants look stressed, just looking at them I would say the root system is in shock, possibly from transplant.
CO2 levels should be maintained and not drop below 1500ppm.
Just plan the best you can on your next grow. From start to finish provide a healthy environment for them. If their aggressive growth is slowed or stopped for some reason, your looking at a long recovery time to get back on track.
Like you already suspected, I think we both believe they are paying for the bad situation they have endored.

I have great plants ,bad set up I guess we all have the big bud dreams ,Definately I agree with conditions first.Build first ,Grow second .That should be the number 1 stickey.BTW why the CO2 so soon?I just lost my virginity but I was under the impression co2 was for larger grows? Proper ventilation and attention would not sacrifice yeild or quality for personal use.
low temps and floros I would rule that out I have clones in rockwool under 55-60 f and they thrive
Advanced nutes ?Use the KISS method no insult intended
CO2 ?I dont know any thing about ,but I do know if you keep guessing that its the problem shut it down before you blow the house up with the propane.
Not to be an a-hole but you seem more concerned on the new toy

I know I'm worrying an awful lot, but.... it worries me.

Another thought is that I am using the AN additives with the GH floranova for a base nutrient. Could this be causing a deficiency since it is meant to be used as a one part? I have been mixing the additives to half of the target ppm, and bringing up the rest with the floranova. I dont feel like buying more juice, but I have the GH 3 part stuff, should I use that instead of the flora nova?

If they get rootbound they will start to yellow and have problems. The roots are inhibited from uptaking nutrients properly, mostly the nutrients wash over the roots and away, not contacting the inner roots that are all jammed together.

anyone have any suggestions for recovery, or remedy?
