Hi all tokers
As the title say,every time I grow plants in dwc,I see Ca def.
I think Ca is the guilty at 90%.
No matter what strain I grow,all of them show similar burns and spot.Some strain will show the def. later than other but the result is the same.
I use to keep pH around 5.8 first and then low to 5.5
RH% and temperature are under control and traspiration is ok
Now I have 4 plants in an r-dwc system and the first signs are appearing.
My tap water has 0,2 Ec
I use dutch formula nutes,with enzymes and a growth stimulator.
It seems to return all normal or at least slow down the deficiencies when I change the whole water in the system,and this let me think about Ca....because in tap water there is a little amount of Ca and Mg,but I don't think it's a Mg def.
I tried to add liquid Ca in the reservoir,but it seems to do nothing.Only thing that really help is to add fresh water,but adding and adding and adding it's a waste of water,and nutrients btw.
What can I do\buy or whatever to fix this problem?
Some shots to let you understand...
These leaves come from a past grow,the def. in various stage
These picture show the def in my current grow.Maybe they're a little different but I'm sure the cause is the same.
This is a NYCDxBB (leaves with more damages are the leaves exposed to a lot of light)
This is a kushage and it was the first to show this def just 48 hours ago.She had wilted leaves also before this def. appeared.
This is the def on a grapefruit.This plant has only these burned spot on this leaf and stop.Sign that it needs less Ca than others.Hypothesis confirmed by the other grapefruit plant that doesn't show anything wrong.
Thanks for any help guys
