    Hi All

    I Have A Plant Growing In A Pot Which I Leave Outside During The Day And Leave In During The Night. It Has Started To Get Pale Yellow Spot On It. CAN Someone Please Help Me As I Do Not Know What Has Caused This. I Have Checked For Bugs And Spiders And There Appear To Be None On There. Could This Be Caused By Over Watering?

    Thanks

    Hello Harmony : )

    AT first glance , it does not look like speder mites..

    Are you feeding your plant and ph-ing your water?

    It does look a little pale. Since its outside does it dry out every day? How often do you water?

    No I just put tap water.. It has some slow feeding plant food in the soil, you know the little balls. Its only 4 weeks old and has been growing like a champ, even with those spots, they have been on there for about a week and half.

    It never looks dry and I water when I notice the soil is dry, I stick my finger in the soil if its dry I water...

    But now I am concerned because all the new leaves are coming out with yellow spots...

    Hi Harmony,

    Potroast seems to think that the plant is to far into its flowering cycle to need a fertilizer that is so heavy in Nitrogen.. and he thinks that the slow release fertilizer in the soil MAY be enough for your plant...

    His points are valid... yet... i stick with my current prescription.. LIGHT GREEN colored leaves are a sign of NITROGEN deficiency..

    I also can not emphasize enough, the IMPORTANCE of diluting your fertilizer 2-4 times more than the boxes reccomendation.


    And slow release fertilizer works for abut 2-3 months depending on the PLANT....

    and finally.. if you PH your water to 6.5-7.0 things will reveal themselves and adjustments will be easy to make...

    and NOW you KNOWM

    I thought you weren't supposed to go inside and outside, aren't you supposed to stick to one so your plant is comfortable and doesnt get shocked?

    yooo.. i have the exact same problem you two do...

    [​IMG]

    i kindof just sarted watering with bottled water. didnt know wat the problem was so i read up on it. thinkin it was the pH because it can cause all kinds of problems and deficiencies because its a nutrient lock. feeding it will not do anything unless you get the pH right. anyways. i tested my bottled water with my fish tank tester cuz thats all i have, and it turns out the pH was 8 - 8.2 and apperentl that nooo good.

    so does anyone what is causing these yellow spots?

    seems kinda common, i read on another website it could be:

    'MANGANESE (Mn)

    Necrotic and yellow spots form on top leaves. Mn deficiency occurs when large amounts of Mg are present in the soil. Foliar feed with any chemical fertilizer containing Mn.'

    anyone else want to weigh in?

    have you been spraying water on the leaves mid day? cause the light can magnify the sun to one spot and cause burn.

    I just couldn't believe that plant is 4weeks old none of my seedlings were lagers and have never been that bushy in 4weeks but maybe it's my strat. I normally let the plant eat the nutrients from just the first round of soil then at about 4weeks add slow feed fertilizer to the mix maybe I need to dose my plants earlier. Also my friend never uses fertilizer or anything until flowering and has major yields. It does look like the nit is low I normally use a feed similar to 15-10-15 around 4 weeks old my dogs got in my grow box and tore it up bad so now I'm working with seedlings again so I have 2 plants that were germinated first and then I got 3 more to sprout and man those are two weeks old and have only 4leaves but the two that were sprouted a week earlier have 5 sets of leaves I'm not sure what to think I am posting a video on YouTube my YouTube is same as my name on here please coment ony YouTube video as it is my homepage and I'm on an iPod video will be posted tonight after I get back from the movies I know this long and to respond the way I'm asking will be pain but please try ;)
