Help! Diagnosing Indoor LED Grow

Discussion in 'Growing Marijuana Indoors' started by kannabuzz, Mar 27, 2016.

  1. Hey Guys, I really need your knowledgeable advice or suggestions.

    I noticed two of my plants have brown spots on the lower leaves and another has a "crispy" dry tip but it's still green. All of my plants (16 days old) are drooping. I don't know if it's under watering or over watering.

    I've also been dealing with temps getting a little high inside my grow tent. I've been able to lower temps and keep the tent cool but can't find a way to raise humidity.

    Can anyone diagnose what is most likely the cause of this? Any advice and/or suggestions to remedy this problem?

    Help would be really appreciated.

  2. How's the drainage from those cups?
     
  3. I made 3 holes on the bottoms of the cups for drainage
     
  4. Are the holes thick enough for good drainage? The last time I had plants in solo cups like this the holes weren't big enough and I had similar problems. I think I overwatered them a little and without enough drainage they may have had a touch of root rot. When I transplanted them I noticed the roots at the bottom were a bit slimy. They recovered pretty quickly in bigger pots with better drainage.
     
  5. These are the holes

  6. I don't know, man. I think they would have enough drainage with those holes. How often are you watering?
     
  7. I check the weight of the cups and water until they feel really light. I've only watered twice. The first time was when I watered the soil to plant them and last tuesday.

And have ya got that heat prob totally sorted yet? Hope this helps and give ya an idea off wat may be wrong... remember that unless ya kill a few crops by lack off knowlege then ya dont gain knowledge... its all a leanin curve babe. Everyone is learnin all the time x

  9. Forget to mention. Use a root stim wen u water them too. If rooys to bottom i wood repot in a good quality soil. Use perlite or pebbles for air and drainage etc. Due to nutes in soil only water with ph water and root stim . X
