    You should be running 800 PPM by now, up the nute levels.

    One question. You said you did not know the sex of the mothers? If you don't know for certain what the sex of those plants are in the producer you could have a terrible time untangling all the roots that will grow together to get any males out. Hopefully they are all female or you find out before the roots grow too much.

    The brown stuff on the roots is from the Nutes, its not root rot, you'll know root rot when you smell it. Nothing to be worried about, don't worry about that one leaf with the brown spot either, it doesn't mean much.

    I will post a Pic of my grow since its at about the same stage as yours if you don't mind. We can compare a bit and make notes.

    I dont have to change the whole reservoir to add nutes right? Which Advanced Nutrients nutes should I add to up the ppm until I change out the whole res on Monday? Or should I just change the res now?

    Dude, I am so pissed off right now... at no one in particular. I woke up to find this problem on my plants spreading. I did research last night, and I know this isn't nutrient burn. If anything, my nute levels are on the low side. My ph was reading 6.0. I've been trying to keep it lower, but my tank naturally raises ph throughout the night. I knew this was a nute deficiency, but couldn't figure out why.

    Then it occured to me that I should check the accuracy of my ph pen and calibrate. Now, don't get the wrong idea... I've been recalibrating about once every 5 days to be sure (and storing the pen properly, keeping the censor in a ph solution). When I put the pen into the ph 7 solution, it read 7.6. This means my actual range has been more like 6.5 to 6.8 and sometimes higher until I could adjust. I attempted to lower the calibration with the screw, but the device refuses to lower below 7.6. It will raise, but not lower. I figured my best option was to raise to 8.0, retest, and add 1.0 to my reading until I can get a new fucking pen.

    :wall: :wall::wall: :wall::wall:

    Edit: I am using the Hanna Chanyn (sp? can't read the cursive)

    Yes BOng i believe a few of them have nl crosses, I have white widow, blue widow, moby dick, blue hash, NYC. They have doubled in size and nyc the biggest is a bout 5 feet now. Ive topped all of them a few times and have several colas forming.

    I also had a problem with my ph pen yesterday. We should have the same one if you got yours with the producer. It started acting up and was giving weird reading jumping. Tried to calibrate again but would just jump like crazy. great broken! I put it back it its storage solution. Tried it again today, this time it calibrate correctly, started to work fine. Dont give up on it just yet, may work after all. If it still isn’t working try pulling the paper out as directed in instructions, this will repair it and can be done 20 times. It also has a 1 year warranty.

    U can add nutes directly to your hydro tube but mix well and don’t over do it.
    But it makes more sense to just drain tub and add the new batch of water/nutes. Replace this next week today.


    Your plants may have just had a deficiency because of the ph. When my seelings are starting to veg all there new growth comes in as lime green. Your plants will survive just keep us posted with pics

    The PH and TDS pens they supply with the boxes are crap, I use a high end Hanna meter with replaceable probe that has done the job for 4 years now.

    I talked to a rep from BCNL for awhile about this leaf problem. He advised me to replace my res with half the nutes I currently have. He doesn't think this discoloration would happen from too few nutes at this stage. He also doesn't think a ph variation of 0.5 is going to make any noticable changes in the short term. Sounds reasonable. I flushed the rockwool with pure water as well.

    I also bought some Garden's Cure neem oil solution and sprayed somewhat as a preventative measure, but I did see a little black bug, maybe a mite.

    About the ph pen... It is not calibrating down, so they are sending me a new one.

    Day 21

    I've cut my nutrients back to under week one levels and the plants seem to be stabilizing. Why are these guys so sensitive to nutes? The new growth looks a lot better, but the stems that carry the leaves are very reddish on some. Mean anything?

    PH: 5.9
    Water PPM: 50
    Nutrient PPM: 280
    Light cycle: 20/4
    Lights: Two 400 watt MH, One 125 watt CFL

    Spots on leaves. Some of the lower leaves are turning lime green or yellowing. What is this?

    i swear ph is supposed to be 7, and roots supposed to be white

    pH should be higher in soil grows. Roots are white. The nutrient solution has stained that portion of the roots.

    Looking good, your about done seedling stage and ull see your plants stop dropping and will raise up, roots looking awesome. Spots on leaves will just die might happen on the other side of plant aswell but that is all good it happens. And ph of 7 is crazy i never go over 6.4 for soil

    Red/purple steams will go away some will stay its normal. Plant will be able to to handle more nutes after seedling stage is done. I dont see nute burn so i dont think u should cut down on nutes. Shit happens leaves die, get dark spots, its all good.

    This is an estimate based on the following...

    Approximately one month
    KWH of $0.12
    800 Watts of MH or HPS lighting
    125 Watts of CFL lighting
    937 Watts of portable a/c (only calculating additional usage)

    20 hour cycle = increase in $117.71

    12 hour cycle = increase in $63.57

    Notes:

    -It costs me an additional $15 monthly to run the vegetative cycle 2 hours longer each night.

    -This is not taking into account electricity usage from the five ventilation fans, pumps, airstones and LED lights from the computer.

    I think the producer uses 9 amps. As an entire unit uses a lot less energy than those bulb calculated separately.

    Hmmm, we shall see when the bill comes due. I was using a growers energy calculator.
