I have had severe issues with both my pH pen AND my ppm pen.
Bluelab pH pen and EC pen have both been ordered and have now arrived.
Turns out my pH pen AND my ppm pen were BOTH reading far too low.
Both of these combined meant that I was overfeeding my plants AND my pH was 6.5 instead of 5.8
I have flushed the res out and replaced with fresh feeding.
the ppm/EC was increasing even with the lower feeding, so I have added pH'ed water to the res for a few days now to try to get it to the level where the ppm stays constant while the plants are drinking. It is ALMOST stable now, but it is definitely getting there.
Here is a pic from 3 or 4 days ago:
Here it is currently:
There is definitely still some clawing and the leaves are very dark, so I may need to back off a touch more for this lady.
Just measured mine and it's 9cm @ day 21 (another 3cm to the very top of the plant rather than the top of the new growth)
I had pH issues and nute concentration issues last week, so it may have become a touch stunted (hopefully not).
DWC on the other hand starts off slower than soil, so I expect it to be smaller than yours until it finishes veg.
It is about the age now when I would expect to start seeing some growth spurts (once it recovers from the topping).
The roots are building very nicely and look a nice healthy colour (if you account for the fact that the nutes I am using stain them slightly)
Firstly thank you for getting this diary up and running mate we can't wait to see what you can do with our pure cbd lady in auto flowering form
Secondly I'm sorry that shipping sent photo critical and not auto. This is an easy mistake and I thought I had send 10 fresh auto critical out. Sorry that they have not arrived. Drop me a pm and I'll look into this
And finally I'll be along for the ride and watching with interest to see what you can do with our Dinamed auto cbd
Good luck mate I'll drop back in on the next update
Day 30 Update:
Still suffering from a slight N Toxicity.
Bushing out very nicely though.
I have dropped the feed amount again due to this and the 4AM being very light feeders compared to the Northern lights and Dark Devil, all sharing the same system
