    Shes a tad overfed lower e.c .2 . Them lower leaves is nkrmal they yellow since they dont get much light . But i do zee a tad of mg defiiciency . Get some epsom salts 1teaspoon and mix up with plain water and mist her real good out of direct light . Mist under the leaves

    Try mixing in some bottled water to bring the background EC down....

    Thanks very much guys

    I will do what you both have said and update.

    Out of curiosity if I'm feeding to high how are they still having defiencys is there anything I could do on the next run to prevent this happening again

    I did get a water analysis done by growers ark not sure if this would make any diffrence

    nearly all nutes are to low in mg imo and i see mg def there , add mg to every feed i like the gold label mg its liquid and easy to use .5ml per l

    and lower leaves are often discarded when not in good light, the tops look good touch of nute burn on the tips but it will get through it, dont go any higher with nutes id reduce and add mg

    is there much led in there?

    background ec of .8 is high , that could poss be sth if u suffer over and over

    Ooof with a background of 0.8 that's even worse than mine!

    Great advice with mixing it with bottled water..which is what I'll be doing for future grows with my background EC of 0.6

    RO is also an option then mixing it with normal tap water, but they can be an expensive investment and can also be expensive to run if you're on a water meter as they tend to 'waste' a lot of water.

    there are some single stage filters around that remove a big chunk of the large particals and quite cheap, perfect for our use , ive seen them on some growshop sites , sorry i dont remember which, ill look for it im now thinking maybe wrong

    Thanks again for the replys funny you should say about the ro filter I was looking at getting one once I realised my water was as hard as it is. I'm not on a water meter luckily so it may be a option.

    First grow so I'm still learning its surprising how much I worry about them lol.

    Thanks for all the replys guys you answered and gave me a resolution for something i have been looking up for the past 2 days.

    Yes, I do believe you're right Forest as another member also spoke about this with me..those quite possibly would work too and cheaper to buy!
