1st grow flowering - problem diagnosis needed (pics included)

Discussion in 'First Time Marijuana Growers' started by stringless101, Sep 1, 2015.



  1. so this is my first grow ever. i have 4 blueberry kush (autos) and one creme caramel (not auto). everything was going well all through flowering but now they seem pretty late in and i am starting to have problems that i can't seem to find answers for. the main problem is the older leaves yellowing/browning number 6.jpg number4.jpg and in some cases, dying number2.jpg . the newer leaves seem to be ok at the moment. number 5.jpg


    the only things i can see that resemble this are; 1. cal/mag deficiency 2. sulphur deficiency 3. lack of light very possible as the weather has been bad for a whoe week now)


    i used plant magics oldtimer on them when in veg state and switched over to platinum when they began flowering. the CC is has not begun to flower but is having the same leaf browing issues that the others are.


    as this is my first grow i neglected (on bad advice) to make a grow diary so not sure how far they are along but it's about 3 weeks. also one of the BBK is extremely small (as you can see in the comparison pic, furthest to the right number1.jpg ) compared to the rest.


    i really just want to know what the leaf problem is but any other advice would be invaluable, i live in a place where it's so hard to buy that my year is riding on this. i made a couple of other threads earlier in the grow and only got one reply so would be great if a few of you could help me out, even if you can give an idea on how far along they are or how near to harvest number 3.jpg . really appriciate it!!






     
  2. They look good. Are the ones yellowing and dying at the bottom?
     
  3. Those girls are root-bound. Planters are too small. Get in to like a 5 or 3gal.
     
  4. yeah, the yellowing ones are at the bottom. i just had a real close look and i found some sort of white larvae just under the soil. could this be affecting the plants
     
  5. How long have you had them? What type of medium are they in? I haven't heard of Platinum is there a link?
     
  6. I'm going to guess white larva aren't doing any justice... It looks like a deficiency or a toxicity to me and since you say they were fine up until flower when you changed your nutes, I would say your problem is most likely in there somewhere.


    I would flush and look at your nutes...


    A larva pic would also be good...
     
  7. they've been in flower for about 3 weeks and the problem has appeared in the last few days. I suspect the larvae are fungus gnats or root maggots. I'll try to get some nematodes today and try them. I've never flushed before, but that's worth a try


    Here's a link for plant magic platinum, it was highly recommended by the hydro store guy for flowering.


    Can't seem to copy the link but if you Google plant magic platinum it comes up first








     
  8. here is the larvae pic. i'm guessing fungus gnats or root maggots but whatever they are my plants seem to be dying fast

  9. [​IMG]and here is the plant that was most far along. it seems to be dying, does anyone have any ideas as i'm close to giving up hope. i feel a bit heartbroken to be honest
     
  10. When in doubt flush it out! I don't know what else to say... Looks like burn and lockout happening to me! I haven't tried all the organics out there yet.. teas and such... I have only been seriously growing MMJ about 9 - 10 months.
     
  11. In fact, I would just use water for a couple days depending on how much she drinks. Don't give up! I had a very rough grow last one myself and I get a good return anyway, but it was a tooth and nail fight for me...

  12. thanks so much for the replies, put my mind at ease at least. i flushed all with tap water and picked out any larvae i could find (a remedy for that is in the post). then i changed the big caramel creme to a much bigger pot i found. i think the fact a few things have gone wrong at the worst possible time has hit me really hard. sounds strange but i've never really put this much effort into anything, the plants feel like my girls! can't wait to read that journal now as well!
     
  13. is moving them to bigger pots while flowering ok?
     
  14. Hit the nail on the head, i've seen conversations about the first growers "babies". I'm 22 days into my first grow and my girls are my babies, things keep happening and i freak out every time even though so far everything has been easily fixable. I thought i was killing them last night and they were just thirsty. I lost sleep over it. . . Hope you have success on your fix man.

     
  15. Well they won't like the move. But it might be better for them then being in those little planters.
     
  16. I have never tried it, but I have read that part of a good flowering is in part induced by smaller pots limiting root growth. However, if you have already... I'm sure you will be fine!

    Like so many others... We all panic because they are our babies! At this point I can't bother with every funny leaf I see. The majority of my leaf problems, short of PM stems from poorly PH water. 90% of the time it's because I had some water I didn't check for a day or two and I use it accidentally. I will tell you I have plenty of pics of me freaking out over my first 12 seeds I had in rockwool. I was flushing and checking PH going in and out... Blah blah... The next time I just watered those babies till the water came out each time. Rockwool is not so PH friendly, so they squirmed a bit but then took off like gangbusters. I have yet to lose a plant.

    Sometimes you just do what you can do and look away!

    The great part is we all get a lesson here! I suppose that's why we're here. Sharing our passion and learning from others.
     

  17. It is best to keep your cannabis plants in pots varying between 1.5 – 3 gallons, 3 gallons being the norm (1 gallon is 3.8 liters). If you have a lot of room in your grow space then you may even want to consider 5 gallon pots.

    What is the reasoning behind this? Well, marijuana plants grow long, winding roots; if they are restricted your roots can become “pot bound”. This simply means that there is not enough room for your roots; they cannot develop fully and thus will not be able to supply your cannabis plants the nutrients to the extent they require – leading to nutrient deficiencies.

    3 gallon pots tend to be the most commonly used pots, these offer a good balance between pot size and room to grow – your cannabis roots should have adequate enough room for a decent grow, whilst the pot doesn't take up too much room in your grow room, allowing you to grow more plants in a restricted space.

    As previously mentioned, if you have enough room, you may want to consider 5 gallon pots (or even bigger). The draw back of them is that they take up a lot of room, so it can be fairly restrictive in smaller grow areas. However, if you have the space then it can help with the production of some big yields! (light, nutrient and other factors permitting). Having a 5 gallon pot allows enough room and freedom for your roots to grow to their full potential. Cannabis tends to do most of its root growth during the vegetative stage, by encouraging huge root growth early on in this phase you set yourself up for some potentially solid yields - by having an abundance of roots towards the flowering phase your plant can take up all of the water and food it could ever need, accelerating the amount it can grow. It should be noted, large pots are an enabler; they do not directly cause better yields, but have the potential to facilitate a situation where it can happen.

    You will want to make sure that your pots are perforated (have holes in the bottom). These should rest on small dishes within your grow room. This allows for easier watering; it makes sure excess water can rest in the dish without flooding your pots – you can then remove this excess water from the dishes at will to ensure that your plants do not end up being over watered. You can also opt for putting your pots into large trays, this a more professional approach as you do not have to worry about each individual dish, but makes it harder to empty out excess water.

    Make sure to thoroughly clean you pots before bringing them into your grow space, there may be chemical residue or other impurities left over from the shop or factory. It is also important to only put one plant in each pot, no matter what the pot size is. This will stop any need for competition between plants as well as make sure that any problems that may occur are isolated – should the soil in one pot accidentally build up toxic levels of nutrients, it will only affect one plant.

    As you can see, the size of your plant pot can have a large impact on how your plants grow. It is most important to make sure your roots have enough room to develop and grow, otherwise you may find that you have a stunted plant. Giving your plant more room than it needs can let it really flourish. However, you must bear in mind, whilst having to little room will definitely negatively impact your plant, having loads of room is not going to get you extra results unless other, more important factors such as light and nutrients are at optimal levels.
