CO2 overdose?

[seldomBLUE]

Is there anyone out there familiar with the effects of CO2 OD. It's the only thing i'm doing different from last season. Still using 24-8-16 for veg and 6-12-6 for flwr. This season i went with a home brew of 4 cups water, 1 cup sugar and 1 tsp active dry yeast. I figured it gave a good boost to the veg growth (19 internodes at 45 days of age) but i'm wondering if it became toxic after too long and caused the problems i'm having. Epsoms salt had no effect on the lower fan leaves even when sprayed directly. The newer growth is folded in like a willow leaf. The smaller leaves along the shoots are curled and growth is stunted. Different ferts (24-8-16/6-12-6) shouldn't produce the same symptoms but that is the case. I know i need to flush so no need for any one to suggest it.
I'll figure it out eventually but i'm asking a specific question and am seeking any one with the specific knowledge of CO2 OD and it's effects

wow I feel for your problems dude. I am a Novice perfoming my first grow and my baby's from seed started in hydro and had probs switched the survivor to dirt and its thriving now but so far 7 nodes (Pic below of the lone survivor) still got a while to go.

Anyway for the home made CO2 your using i did do some reading up on this and am wondering if your changing out 1/2 the solution and refresing with fresh water and yeast either daily or every other day not sure off hand. from what i hear if you dont do this the solution gets rancid and Im not sure if will effect your plants.

Also are your temps high enough for CO2? from what I understand unless your lows are 85 and highs around 90 CO2 fed plants thrive in that temp range with CO2. and have you increased the feeding, I'm to understand the nute requirments need to be raised to a higher ppm?

Now mind you like i said above i am a novice and I know you could get better advice and input from those with a few years under their thumbs. but since they didnt chime in yet I hope what I said gets your grow going in the right direction. finger are crossed for your babes as well

That's the same thing i figured. It's the only thing i've changed from last seasons indoor closet grow (veg) and outdoor greenhouse grow (flwr). I was changing the bottle out every 10 days or so, but I noticed the funky smell within 3-5 days. This is SW Tx, temps 90 nt - 106 dy in my outdoor 12/12 and 76-80 in the closet 24/7. That had to have an effect. Glad to know that some one sought the science.
That was part of the problem. The other was a very bad pH. I did the MG, Ocean Forest, Happy Frog, Soilless mix and it all went acidic to around 5.8pH. I had to repour 1gal wtr (reuse the same water and readjust to 6.7) every watering before the fert schedule.
One thing I discovered was that my runoff pH went further acidic when the ferts were adjusted from a +ph down to the target pH. I found that adjusting about .5 below the target pH and neutralizing up to the target held the pH closer to the target between feedings; only droped to aroung 6.3 pH.
Then i thought the salty air here helping to suck the leaves dry. I would mist and mist not realizing that i was washing all of the salt off of the leaves and right into the soil. The salty air faded my cars paint. I found that i could reduce the amount of salt in in the air inside my grow with 1gal H2o (milk jug)-1 small box baking soda-aerator. I'm not sure of the science behind why it workes but the leaves didn't taste as salty. Maybe somebody else will take a stab at responding with discovery science. May not work in your neck of the woods as H2O content differs (pH,cholorine,flouride..etc). My pH was the one thing that had to be corrected and maintained. pH,pH,pH! Did i mention pH? Nobody seems to mention the severe importance of proper pH for soil growers, so here it is.
pH-pH-pH-pH-pH-pH-pH-pH-pH-pH-pH-pH-pH-pH-pH-pH-pH-pH-pH-pH-pH... Also, i use enough wrt or fert (plant drinks 1/2gal so i use 1gal to be able to check and adjust the pH if necessary. I do that every wetting so i can keep track of pH. Like i said, this isn't for everybodys' situation but in 106deg, 80%RH days it works for me.
She's doing so much better. Thx for the input
