Slowly Getting Worse!!! Any advice welcomed.....

[skptrcr1]

This is my first grow and trying to keep them alive.

Type: Aero
Medium: Hydroton
Water: Distilled
Reservoir: 20 gal
Humboldt Nutes: 100ml Oneness; 60ml Sea Mag; 40 ml Sea Cal; 40ml Flavorful; 100ml Prozyne; 40ml SI; 40ml Verde.
PH: 6.0

It all started with mag def, but seems to be getting worse. I was using my tap water but it had too much cal in it. I figured that too much calcium and salts had built up on my roots so I flushed my system using Clearex for close to 8 hours prior to refiling it with Distilled water. This still doesn't seem to be working..... Any Ideas????

whts the ppm? Almost looks like a macronutrient def.

It really just looks like nitrogen def. but if your sure it isn't then idk. Try some N only fertilizer and see what happens You could be doing all the right things, your plant could just be the type that needs more food than others.

It does happen even among the same strains.
Right now I have 7 plants in flower and was feeding them all the same and all did fine except 1.
The one that had problems was still growing and all but showing deficiencies and such.
It is a Sannies strain and he recommends consistently light feeding but I was doing feed water water feed with a nice heavy dose.
So now that one plant I feed differently than all the rest and no more problems other than being very ugly from not enough food in the beginning.

Anyways when I have a problem I like to use this little guide. It is from another site and there may be one similar on this site but I like this one the best.
