Houston....We have a problem.

Hi All - just joined the boards a couple days ago and posted a little about my setup in the Introduction Forum - but I have a problem with my babies and need some expert advise.

About my current setup:

(20) 6g. RDWC buckets.
Canna nutes (A+B+Rhizo+Cannazym)
RO Water (I think this is where my problem lies)
24hr Lighting
(6) 1000W MH @ 6K
Air Cooled Hoods
Ambient Temp Avg. (Today) - 80F
Water Temp - 68F (1000ppm / 5.9pH) - Flucuates between 6.0 and 5.8
Plenty of air to the stones - good air turnover in the room

So - what I think I have here is lack of Nitrogen and a Calcium and Magnesium deficiency - BUT - I need your help!

If I didn't include enough information, please ask and I will get the info posted ASAP.

Thank you in advance for your time and assistance!

try ppms at 600-700

Thanks for the feedback 'Y' - I am concerned about just watering down the nutes though - especially with RO water. My thoughts behind that are: If they ARE lacking in Ca or Mg then I feel that I am further reducing the Ca or Mg by watering it down. Are you suspecting nute burn? If so - how are the spots on the leaves and the tip burn explained??

I don't know for sure - but I think it may be a little more than just too many nutrients. (No insult or depreciation of information meant)

BTW - If it matters: All new growth is looking AMAZING and growth rate is much higher than expected. The strains are Gods' Bud / Blue Dream / Alien Dawg.

Looking forward to hearing from others!

And thanks again 'Y' for your response!

they look over fed and do not appear to be lacking anything so i say dilute your solution

here are pictures of lacking potassium but i still think your ppm is high for using ro water on such a tiny plant

Thanks 'Y' for that picture - helps a ton. I think that it must be a Potassium problem. The plants aren't THAT small and have been in this kind of mix for over a week - maybe just bad close up pictures. I'll go take some of the overall plant and re-post in a couple minutes.

It really is awesome what forums can do for society. Be back soon. Thanks again, Y.

Pictures of some of the culprits:

the pics are clear with their visibility so i would say that it must better be shown in clearer format for the best things.

I'm sorry - what?
