    Whatsup decided to post another grow on here. Started these 2 feminized Dark Devil seeds from sweet seeds @ attitude seed bank on December 27th. They popped with their cotyledons on Dec 30th (day 1). Here are some updates pictues:

    2ft x 4ft x 5ft tent with an 8 inch hyperfan
    Mars II 700w standard spectrum
    70Liters per minute air pump with eight four-inch cylindrical airstones, four for each plant
    5 gallon buckets with 6 inch net pot lids using hydrocorn
    RO water with Gen. Hydro. Rapid Start
     
  4. Im interested in seeing how she grows. Id like to compare yours to my diesel auto
     
  5. Awesome set up mate.  I'm looking forward to seeing this pan out 
     
  6. Hey hey subbed up
     
  7. Dude when did you change your name?  I thought I recognised your avatar 
     
  8. Few months ago maybe? I noticed I had the option and decided to try it out.
     
    One of the plants was killed so now I just have the one. It's not so bad though, I'll get a bigger res for this plant and now it has the whole pump to itself.
     
    Picture update:

    Running at 123ppm right now using General Hydroponics micro + bloom and Earth Juice soy-ful fulvic acid. I already have a ton of GH micro + bloom so I am stuck with the lucas formula for the next 2 grows at least but then I want to switch to earth juice, they are local company and have some nice stuff.

    That's pretty low man,  I would have guessed that plant would be on about a 250-300ppm at this stage.  How's the growth rate at the moment? 
     
  10. Iv grown a bunch of Dark devil. Growing it is more for ornamental or cool factor. The strain is just small and low yielding even outdoors and outdoors with full sun.
     
    Its on my list of strains to not bother to grow again.
     
  11. Thanks for the input, to each their own I suppose.
     
     
    I'm going to keep upping it. The growth rate isn't bad, it's picking up. I should have started adding nutrients besides rapidstart sooner but, y'know, high all the time and taking care of another soil garden.
     
  12. I will be watching this. I want to try DWC soon. Do you know why your other plant died?
     
  13. left the valves for it turned off by accident.
     
    Interesting to note, I increase the ppm everyday and yet when I check it the next day it's always down by 2-5ppm.
     
  14.  
    That's a great sign of things moving a long nicely.  If it keeps dropping just keep raising it more and more 
     
  15. Today I raised ppm to 256 and used h2o2 and some soy-ful (fulvic acid). I also started low stress straining yesterday.

    Something is affecting the leaves, maybe boron deficiency? I have been adding a little bit of cal mag to my solution now because I read cal-mag def can affect boron uptake and it seems like boron to me. Anyone know any better? Other than that things are going well. Except I have algae on the roots because I was lazy and didn't tape my bucket like I should have so I started adding h2o2. Yesterday she was at 331ppm and today she had dropped so I pushed her to 384ppm with 3ml GH micro, 6ml GH bloom, 1ml calimagic (5% ca, 1% mg, .1% fe, 1% n), and 1ml soy-ful

  17. How much h2O2 did you add? Why did you add fukvic acid? Was it the correct dosage? 
     
    Are you using tap water? What is the EC or ppm of the water you use? 
     
  18. Water is RO/DI, 0ppm. I added 30ml h2o2. I added the fulvic acid to supplement nutrient uptake, it's supposed to work as a chelating agent. I put it 1-2ml at a time at most, the bottle has much higher ratings on it.
