Growth Fail

[TD.]

I have been doing "trials" on a new growing space before i attempt the main event.

In a DWC setup i have 6 plants sharing the same nutrients, all 6 plants are grown from seeds, all seeds from the same plant, 3 are healthy and growing, 3 have stalled and started to show signs of "?"

 

PH has been 5.7-5.9 the whole time

EC started at 0.2 for the first few days then 0.4 by the end of the first week. gradually bumped it up every 4 or 5 days, currently EC is at 1.2

Lots of dissolved oxygen in the water

Nutrient solution has been Canna

Light distance is not close enough to cause light burn

 

its just strange to see a 50/50 of healthy and unhealthy from the same res......

as for chronmaster im not gonna bug the bloke he might pop in, maybe some1 else will pop in and solve the mystery....maybe the plants will correct it them self......maybe 3 out of 6 will not grow well at all.
