What nutrients are you feeding it ?

am_al_59 · 07-06-2017, 05:15 PM

i watering and use very very liitle nutriens every two day
1 liter RO water
0.1 gr npk 20 20 20 (powder)
0.1 gr micro element (powder)
1 or 2 drop urea
1 or 2 drop silicon
1 or 2 drop cal mag

I'm afraid it's a virus (tmv virus)...?

my micro element nutrient powder contains:
0.3% fe EDTA
5.5% zn
6% b
10% s
12% mn
0.3% cu EDTA

also 20 20 20 nutrient powder contains:
20% k2o
20% p2o5
20% n
0.04% mn EDTA
0.06% fe EDTA
0.015% cu EDTA
0.025% zn EDTA
0.001% mo
0.01% b

I doubt that it's a virus....
In your micro mix, is the 12% you list really MN or did you mean MG?
1 or 2 drops of calmag doesn't sound like enough Cal for coco, but depends on the concentrate your using. Was the coco well flushed and precharged before use?
If there is 12% MG in your micro mix, I'd drop the calmag and urea and use calcium nitrate.
Also, higher temps coupled with lower humidity levels are tough on young plants....slows transpiration rate leading to build up/Nute lock-out/deficiencies

New growth looks healthy, Good luck!

thank's for your reply
it's 12% mn
i think so it's cal deficiency
but i'm afraid maybe tmv virus...
can i use lime for fix cal deciency
my nutrient is 5% cal and 5% mg
i read manual now and see it must be spray on plant but i was irrigating
can i use lime for fix cal deficiency?
