CO2 Problem? any ideas?

Discussion in 'Sick Plants and Problems' started by chotus, May 24, 2023.

  1. Hey guys I decided to use one of those CO2 mushroom bags for the first time. it's in a fairly small area my tent is 2x1.3x2 (60x40x60cm).

    when I added the bag it seems to have effected the plant negatively the leaves started turning yellow and went droopy and started to get burnt tips. I removed the bigger yellowing leaves thinking the were just dying but looking back at the time-lapse it was either the co2 or par? as I turned par upto 950 (autoflower) I have since now removed the bag and returned light back to my norm 750par.

    now have a few kinda patchy looking yellow leaves and what looks to be nute burn on some tips.

    I have supplied I quick clip below where you can see exactly when the bag went in the tent

    just curious what exactly went wrong?

    to much co2 ? extraction fan not going fast enough? or the par just to high?

    Thanks for any help

     
  2. check this no C02 wont turn plants yellow: GWE Cannabis Nutrient Burn

    2x1.3x2 (60x40x60cm). is marginal 3x4' (1mx1.2) is the smallest I go,

    plants need space
     
  3. I never said co2 was the main reason but I know it happen exactly when it went in so something negative happened. so could it possibly be the fact the autoflower can't really take the increase in nutrient uptake or something and that's why the tips have what looks to be nute burn now?

    I have many successful grows and years under my belt bljust first time trying co2 so reaching out for help or knowledge of what happened

    we all know it's not the grow space I have grown in smaller and so have others.

    thanks for the reply my bro
     
  4. Yeah I have been looking into this. at night I can only get humidity down to around 55% as it is 99% outside and temps in the room are about 19c and 8c outside. since I can't get humidity down low enough as mentioned on vpd charts (19c 38%l my next best bet is to raise the temps instead yeah? try keep it at say 25c and 55% as it is in the day time
