First true leaves turning white at stem?

  1. Hi everyone! I just made this account since this is my first grow and I already know this is the first of many questions. 
     
    Problem: I'm having an issue with my first set of true leaves turning white at the middle/stem.
     
    My assumption is nutrient deficiency, not entirely sure which nutrient though. I started my seed (just one I found in some weed) in paper towels to germinate, then transplanted to a Burpee self-watering seed cell (basically the soil pellets that expand in water). Honestly, I think I transplanted it too late, after the seed had completely come off the plant and the first set of leaves was visible. Oops.
     
    Anyhow, I'll attach some pics of the plant.

    I planned on starting up a hydroponic system but didn't have everything ready by the time my seedling needed to be planted, so I ended up planting it in soil. I want to try transplanting it into a hydroponic system but I think I'll wait until it has a second set of leaves. I do however have the hydroponic nutrients on hand (General Hydroponics 3 part system) and went ahead and mixed up a gallon of water with the correct ratios and used that to water my plant. Hopefully that helps?
     
    Any feedback is greatly appreciated! Thanks  :D  

     
  2. What is that light you are using? Your poor girl is starving for light. I am pretty sure that's the whole trouble, you need more light. Whatever at thing might be it is not a Mary Jane grow light. Stop worrying about about going hydro, nutes and worry about that light. Do not I repeat do not give that plant nutes. Way to early, you need to do some research on growing. It takes 200w or more to grow. If that's an led you need to make sure it's the right kind of led, and min 50-90w just to start thinking of growing. Not 10w
     
  3. Hydro nutes in soil is a bad plan as well. Leads to crazy salt build up and other bad effects, you need different nutes for the future in soil. You can not switch this plant to hydro. Mostly I feel you need to read up my friend.
     
  4. Thanks man, appreciate the feedback. I will add in a 65watt CFL for lighting, was using one before but switched to this light because from what I understood the lumens were the concern, not the wattage, so I went for the correct lumens. The LED is only 2watts though, so adding the CFL should be appropriate, I assume. I have been reading as much as I can, have even taken a class in growing hydroponic lettuce (I know, extremely different, requires more water and it was an ebb and flow system, etc, still have hydroponic experience is what I'm getting at) but I still feel utterly clueless about what I'm doing. Trying my very best though!

  5. Didn't think the nutes would be an issue, I only used the appropriate amount for a seedling and the company website said their nutrients work fine in soil with the recommended ratios for a hydroponic setup. Could be wrong though, like I said, super clueless as a grower!

  6. You are wrong you need to wait longer before you.give nutes to Mary Jane. My led light has 3w diodes but in four 4sets of 25 of them. 200w is more like it than 2w. Lettuce and Mary Jane have nothing in common in terms of light needed. 6500k Cfl look for real watts not equal to watts. 23w equals 100w is the lowest I would use. You need at least 100w real watts just to start. More as she grows, read a marijuana grow bible. Youtube growers and get a lot more light. Again no nutes yet and hydro nutes in soil is a problem. Happy growing

    Right, you said no nutes, but only because they build up salt? Or some other reason? All I've been reading has said nutes are appropriate for seedlings as long as it is at very low amounts as to avoid burning it. This is the first I've heard that nutes are not appropriate for a seedling, which is why I'm asking. Not sure what you mean by "real watts not equal to watts". The specs of my current LED light (Miracle LED Blue Grow Lite, Indoor Gardening Bulb):
    Wattage: 2
    Color: Blue (I've heard blue light helps influence plants to grow into females)
    Luminous Flux: 200lm
     
    The other bulb I'll set up with it is a ~60watt CFL.
     
    Appreciate the advice, I'll look up a marijuana grow bible. Thanks again!
     
     
     
  8. It can't be nutes because your plant is too young. It literally can't need nutrients until the first set of round leaves fall off. I have to agree it's your light. A 13w cfl would be better than what you're using not that you should use a 13w. Really you need at least 100 real watts not equivalent watts or 50 watts per sq foot. I like the sq foot measurement better, it's more accurate.
     
  9. Thank you for that, I wasn't aware of the nutrients not being absorbed until the cotyledon leaves fall off! And I still can't figure out what you guys mean by "real watts", I did some searching online but came up with nothing. Guess I'll keep searching.
    Thanks again!

  10. A real watt is what the light is drawing out of the wall as opposed to equivalence rated watt which is being compared to incandescent light with cfl. Real watt in led is draw power as opposed to rating and number of diodes. Basically it's power draw rating instead of the hyped watt number. You need to look for power draw ratings.
     
  11. Awesome, thanks! I found on the lightbulb itself it actually is 13watts, not 60 as I had said previously. Sounds like I need to invest in new lightbulbs :D
     
  12. I said don't use hydro based nutes in soil because they are not designed for soil. More salt buildup than a soil based nutrient system will leave in soil. Basically use the right tool for the job, go with Fox farm trio it's a good starter nute line. Wait until you have 4-5 nodes until you use any nutrients. Only do this after you purchase a real light system. I am not trying to be rude but it has been stated to you already, you need 100w-200w at 6500k of cfl if that's what you go with for a lighting system. I feel that's probably your best interest as we haven't even got to talk air exchange, air movement, correct drainage, watering practices, training methods etc etc etc. Get some y splitters some clamp lights two four packs of at least 23w cfl 6500k bulbs. Read packages look for real power rating and color temp.
     
  13. Glad u found it
     
  14.  
    Ok, invested in some new CFLs and clamp lights! The ones I got are 75watt, 20 true watts each. The light is 6500K with 1190 lumens. Closest I could find to what you suggested. Sound better? Thanks again for all your help.

    Here's the new setup:
    Currently it's 3 CFLs (6500K, 20 true watts each, and 1190 lumens) another CFL (13 true watts and 2700K) and my blue LED light (2watts, 2600K, 200 lumens). Planning to add more wattage as needed. Bulbs are about 8" from the seedling.

    Feedback appreciated, as always! :D
     
  16. Take the hoods off get the light closer to plant. You need a box of some sort for the plant, storage tote cardboard anything. Get y splitters use less desk lamps. You need to be 2-3 in for cfl lighting to be effective. You need a fan of some sort small 6" is fine. Youtube some storage tote grow ideas. Look into the micro grow threads on here see what others are doing.
     
  17. All great suggestions! Worried my little plant will get too much light, does this look correct?

    I figure 12-15hrs of light a day is okay for my seedling. Throwing a fan into the mix and doing more research. Thanks again for all the help!
     
  18. The lamps look better, 18-24hrs is veg cycle 12/12 is flower cycle. You can go straight 12hrs of light from seedling and if you are growing with this small amount of light. I say small because I grow with 150w per plant of hid light. You are in no danger of to much light zero.
     
  19. Thanks, think I'll switch over to 18/6.

    With cfls it's pretty much impossible to have too much. You can have them too close and burn them but it won't happen with a 20w bulb. You should have gotten a 46w or a 52w. You need at least 100 real watts. Get one 2700k and one 6500k and use them together throughout. Really with cfls it's better to have 150w on one plant. This is all coming from experience. I would personally never grow with cfls again but if you do the only way I would is mixing the two spectrums either 1/2 or 1/3 depending on veg or flowering but slapping two big ones in thee will get the job done with one plant. I'm pretty sure the 52w 6500k bulbs were 12 bucks last time I checked it's worth it if all you're using is cfls. Also you can just take the led out, it's pretty much useless. If you stick with 20w bulbs use a power strip and get T or Y joints and use a mixed spectrum so you'll have 12 bulbs which is enough for a nice hefty plant.
