Started Co2. Help.

[40Below]

I just started the CO2 about a week ago. And this is my first watering since then. I have added Cal mag But no other nutrients other than back guano. Any idea what's going on looks like maybe a little Newburn.

Guano can fry plants if overdone. Not sure if that's the case here but looks like it might be starting. I like bat guano but it is hot stuff. I don't use it now because my 8-4-1 desert bat guano doesn't exist anymore. I don't like the numbers of the other ones. How much co2? And do you have good lighting for it.guano is acidic. Check ph first thing. If way off flush with ph'd water. Neutral is 7.0. It looks acidic. I see yellowing of perelite too. Check ph 1st if it's off flush. I keep soil around 6.2-6.4 ph which is acidic. Look for bugs too even though I'm not thinking that's it here. Nothing flying around or at roots.

Sis you have your room dialed in before adding co2? Co2 can bring out all kinds of issues if your room isn't dialed in correctly. I've been running co2 for about 3 yrs. It's cheaper.to run co2 than my a.c.. and I get more yield vs not running it.

Thanks. I'm running 3k halides right now. 1k led. And a few t5s. I did not check run off. PH in was 6.5. So may be too high with guano. Co2 is on Titan control box at 1500. I think I will do the flush. Thanks again. I'll update in a few days.

I have it dialed in Pretty good. Steady 80F
60-65 humidity. Lights are on movers. I keep them about 20 inches up. I still have trouble with diagnosing issues. You look at pics and adjust accordingly and seems like something else happens. I'll get it eventually. But fuck it's expensive learning curves. Thanks for the input. I'll take all I can get. Hell if someone set up an online business diagnosing plants over Skype one would be rich.

You want to dial back the co2 to 1100. 1500 is too high and will run it too much. I have run co2 for years and can tell you it's best that way. I would say you need to raise lights according to that plant. Looks really stacked and crowded

Also pick up a nutrient line. You should be running mild mix right now. Run a bunch of distilled or ro water and clip the larger fan leaves blocking new growth below.

My rm stays at 1500ppm start to finish. .....

The issue with 1500 is it spikes when filling and if your a bottle baby it will run through 20 pounds in 3 days. 1100 has been money for me. I don't ever spike over 1500

I use a generator. $20 a week for a 6k rm. Do u use a fuzzy logic type controller?......supposed to not let it spike.

1000 suits my plants needs very well.

Co2 is for more advanced growers. Fuzzy logics are pretty to have.

I use my Iponic 624 controller

It is at 1200. Sorry I thought it stayed at 1500. My 20 lb bottle has been going for about 4 days. It appears it should last several weeks at the rate of loss. I will raise the lights to maybe 30"? Clip large leaves. Just flipped to 12-12. Thank you all for the input!!

It won't last several weeks. My 50lb at 1500 is like 6 days. I usually like 1000-1200 seems to do well at that range

Are you in a sealed room?

i get that. Only way to get advanced is to keep on advancing. That's why I seek help here. Plants are looking good after the flushing. I do use Titan control box to maintain my co2. Plants seem to be doing okay after I made the recommended changes.
I do appreciate all of the input from everyone.

Update on co2. I had to check to see if my co2 was working properly. I monitored it for 2 days. Everything is functioning as should be. It's a steady 1200 ppm when it drops to around 1100 it kicks on. Monitored with data logger and video. I don't know why everyone's co2 goes so fast. I am one week in tomorrow and have used about 25% of a 20lb bottle. May be a few factors. I am a commmercial builder. I live in interior Alaska where our building practices are a 100% vapor seal. It only leaks where we let it. I know my room has zero air leaks except at my dump baffles. I am on a 12-12 cycle so only using it 12 hours a day. So maybe this is why? I will continue to monitor it. Maybe I'm doing something wrong? By the way the plants are looking great!! Thanks for all the input!!
