Each row is a new day.
Day 7 was the day where I completely flushed my system
Represented as BOLD

This is the first time using the DWC method.
Nutrients I am using are as follows:

Aqua Flakes A & B
Silica Blast
Rapid Start
CalMag


Tomorrow will be day 10 since I transplanted the clones into
the DWC system and I have seen SLOW to NO GROWTH.

Noticeable characteristics of problems are:


Purple streaking/ purple stems
Yellow hue on new growth leaves (starting from inside and moving outwards)
Burnt/Yellow leaf ends
Spotty burn marks on older growth leaves.

Ive tried to include pictures of some of the things I am describing.

I believe that this is a magnesium deficiency, that is why I added CalMag
to my regimen. But a couple days have passed and I have seen no noticeable
changes.


Does anyone have any idea of what might be going on,
or what I am doing wrong?

Thanks,

1. slow to no growth = the plants are rooting to the water yet. don't worry they'll take off when they hit the water mix

Purple streaking/ purple stems = P is low

Yellow hue on new growth leaves (starting from inside and moving outwards) = Low N

Burnt/Yellow leaf ends = Hot solution mix ratio

Spotty burn marks on older growth leaves. =
Not to worry, but can be pH or Ca/Mg.

The pic of the roots suggest that you should only have the water in the buckets JUST touching the net pot and when the roots a a cpl of inch's into the solution. Let the solution get to about an inch BELOW the net pot.

On the use of H&G products. There are several other things that run with that line ,, correct? You may be missing out on some micro nutrients that are not in the 2 part A and B.

You will only "see" changes in the existing plant for the low N correction.
You need to watch the new growth for everything else.
