  1. I am currently experiencing problems with my Sweet Tooth plant. She is almost 3 months old and halfway through her 5th week of flowering. I started noticing bottom growth shriveling up and blotching on the leaves.

    I'm using:
    80% FFOF, 20% perilite
    600W HPS @ 12/12 w/air-cooled hood
    3' x 4' grow area

    During flowering I have been feeding/watering as follows:

    Week 1

    3/4 gallon of tap water @ 6.8pH, twice per week (Wed & Sun)
    1/4 Dose of Open Sesame, Big Bloom and Tiger Bloom two times that week during watering

    Plant was very healthy at this time with no noticeable issues.

    Week 2

    3/4 gallon of tap water @ 6.55pH, 6.7 runoff twice that week (Wed & Sun)
    Full doses of Tiger Bloom, Big Bloom and 3/4 dose OS, twice with waterings

    She still seemed very healthy at this point.

    Week 3


    Approximately a gallon of tap water @ 6.8pH, every 3 days
    TB and Big Bloom full dose, 1/2 dose Beastie Bloom, twice (Wed & Sunday)

    Still healthy.

    Week 4

    1 gallon of tap water @ 6.8pH every 2-3 days
    Fed 1tsp molasses to 1 gallon on Wednesday with full dose Big Bloom

    Fed full Big Bloom, Beastie Bloom, Tiger Bloom and 1/2 dose Grow Big on Saturday


    On Sunday, noticed lower leaves were shriveling and looked burnt.
    Top leaves and new growth were browning on tips.

    I don't have a picture of the said undergrowth for this week.

    Rest of the week I only watered without nutes. The next watering I gave pH Down and brought the water's pH to 6.7.


    Week 5

    1 gallon of tap water @ 6.7pH every 2-3 days
    Gave pH down last friday (Sept 10)
    Haven't given any nutes since Sept 4.

    Not only are the under leaves curling up and burning, but the upper leaves still have the browned edges and tips.

    The upper leaves are also getting very splotchy and look like burn spots. Looks like it could be all sorts of different deficiencies, and many of them look the same so it is very hard to tell.

    Can anyone help identify what this problem is? Don't want her to get past a point of recovery. Thank you in advance! :D

  3. Dude,

    Thanks for the thread, however, I've read many a threads about deficiencies and toxicities. I can't pin it down which is why I'm hoping for a more experienced point of view.
     
  4. No expert here but I looked up the symptoms you are having and it looks like the first picture with the curly leave could be from Chemical burn.

    And the spots on the leaves look like you may have a maganese, iron or nitrogen deficiency.

    Looks mostly like maganese because the spots are yellowish but I listed all three in case my monitor doesn't show the correct color.

    Look up the symptoms for these and see if you can nail down what it is.

  5. Dont disregard the other info posted first but to help narrow it down, it sounds like the type of ailment that is cause by elements that dont move, cant member what its called, too stoned, but its cause the ailment started in the older growth first, find the immobile elements and start from there, with the other info posted this may help. either way best of luck man.
     
  6. I had this exact issue during my last grow. I fixed it by adjusting the ph in my nute water and regular water. I also bought some cal mag which is what I think fixed the problem. I believe you are experiencing a mag deficiency. By some cal mag because all FF ferts are missing that key ingredient. ;)
     

  7. I would give it a good flush first then give it the cal mag.:)

    my leaves looked very similar and i was certain it was a calcium def so i gave my plant cns-17 nutes @ 20% strength along with a TSP of Epsom salt per gal of h20 and it cleared up in about 4 days as no new leaves showed the spotting nor tip drying. as a precaution i put a tsp of epsom salt in all of my water and nutes and the spotting has never returned.
     
  9. I was thinking magnesium, it's just so incredibly helpful to find other people who've had the same issues. Thank you all for your replies.
    I'm going to pick up some cal/mag tomorrow and feed her some... After a good flush. Let you guys know how it worked out in a few days.
     
  10. No problem man! I got that info from GC during my last grow so was was just doing whats right and passing it down to the next connoisseur. Best of luck too you bro.:smoking:
     
  11. if you are gonna use so many nutes at once then dilute the strength a little more. let us know how the cal-mag works.
     
  12. i dont know whats causing your problems, but as far as your feeding regimen, maybe cut back a little. im pretty sure your suppose to use nutes every other week.
     
  13. I flushed 4 gal. of pH 6.7 water through with one of the gallons containing clearex. Then I watered with another gal. containing a very low dose of ferts and the Cal/Mag. So far hasn't gotten any better but doesn't seem to be getting much worse. It's only been 2 days now, hopefully she'll show some signs of improvement in the next couple o' days.

    I'll update in a couple more days with more results.
     
  14. If the problem doesnt get better I would flush your soil with 3 times the amount of PH'd at 6.8 water than your container size.(i.e. 3gal pot = 9gal ph'd water) Then you should wait for your soil to get pretty dry. 2 to 3 days at least. If you see slight wilting in the leaves u should definitely water it with some cal mag now. Be sure to PH your water. The FF trio is hard core. I would really consider dropping some of the nutes. Using the solubles and liquids at the same time seams like a little overboard. I use only the trio. open sesame, beastie bloomz and cha ching. I also only use them at 1/4 to 2/3 strength at most. Depends on how well it reacts to its first feeding at 1/4 strength. good luck bro and I hope this helps.:bongin::bongin::bongin:
     

  15. I also make it a regular habit to give mine 1/2 dose cal mag every 2 weeks.
     
  16. So it's been a couple more days now and It does appear to be getting better. I'm going to water today and add the cal/mag again with another dose of nutes, maybe 1/2 strength. I've only got a little more than two weeks till harvest. Any recommendations as to when to stop ferts all together? I was thinking of adding ferts today and then a last feeding come wednesday. After last feeding only feed ph'd water and Blackstrap molasses for the next couple weeks. Three days before harvest completely flush her out. Is this a good plan or does someone feel there is better way of going about it? Thanks, Darkx
     
  17. Okay now, It had appeared to be getting better. Now it looks horrible. I've got the same problem, however now it's spread to almost the entire plant. I've been researching and researching and I still believe that it is a magnesium deficiency. Not from a lack of Magnesium, but an excess of Calcium. I've been watering with hard water and think this is the root cause of the problem. Anyone else have troubles such as this before?... Calcium toxicity? Thanks, Darkx
     
  18. I would suggest doin the flush with 1/4 tsp per gal Epsom Salts. They aid the plants uptake of Ca/Mg.

    Then start the Ca/Mg.

    :smoke:
     
  19. Hmmmm. great advise. I'll remember that if I ever run into ph problems again. +rep
     
  20. Ok... My soil finally dried out enough to water again. I stopped using my tap water and bought some filtered water from the store. Fed her some epsom salts and bs molasses. We'll see how it goes, but with a little more than a week left I'm not expecting any sort of a full recovery. Let y'all know how it goes.
