You’re an absolute gem. The seller seemed very keen to please and I haven’t left a review yet, I’ll give him a day or 2 to reply and if no joy then I’ll get one ordered.
I’m not too worried. Iirc when I ran straight tap and added the hydrocrop to EC 1.9 the pH sat around 5.9 for around 4 or 5 days before I started seeing a slight pH drift. I’ve still not used any pH down yet mate 
all looks good though
I hear the Athena people have growers running 4+ EC with massive runnoff to waste 
Crazy IMO
I was planning to maybe push to 2.5 the end of the grow to be honest bro. They seem happy with the 2.1 at the moment. (my tap water is 0.3 so I guess I’m actually at 1.8 with nutes) EC4.0 seems like madness. Unless they’re keeping regular feed and topping up with PK, sulfur and magnesium at the end 
Are all their plants purple when they finish?
No idea 
just heard from a local bottle head 
Fair enough is that bro. I’m quite impressed with these SB autos so far. There’s going to be some stagger between harvests so I may have to leave a couple of the lowers on the earliest plants to be chopped, So the roots don’t die and mess up my other plants with pythium or the likes.
I may try a single plant at EC 4 in the future 
Next run my 2 45l tubs are being turned into a RDWC (2 cable glands and a bit of hosepipe to join them)
Plan to run photoperiod next smoke run. But a seed run in between
Looking good bro I’ll post some updates of mine shortly I gave them all a nice lil hair cut at the bottom where the leaves were looking a bit tatty your and mine look so different though
Nice one brother 
they seem to be coping pretty well considering the minimal effort I’ve put in. I did take about 5 or 6 fan leaves the other day to stop leaves sweating and increase airflow a bit. But not too much as to stress them.
Get a few photos up later be good to see the difference. A obviously it’s the same genetics. But it’s different feed, light and medium. So it’s kinda expected
