So,here's the update, finally. Apologies for the delay, life, kids etc.
I was thinking a little more last week that maybe it was nutes burning the tips, not light as I had assumed. I'd topped up the res a few days before so I went back and re-took some measurements and then had a quite awful moment of clarity/understanding whereby I realised I'd been reading/using the wrong values for the EC (quite embarrassing tbh!) and that I was waaaay out to where I thought I should be and was concentration wise.
Anyway after some thought I decided om throwing away what was in the res starting afresh with new water. I also decided to switch from my tap water to RO water which is the purified water I've used all along in my grows (never realised it was RO until I read the label...lol!) Lower EC and crucially pH as was having trouble with that as well. The pH constantly drifts up though I have to say but at least I'm aware of. It is a much better (and more stable) option than the tap water so feel far happier with it.
So on with that and seems good so far. Or at least feels I have more control with it. Lights have been turned up (appox 600PAR) at highest canopy and airdomes came online two days ago (that was a fun setup...lol!) I slightly increased the feed in the res and will increase it up again next top up I think.
We're just in to week 7 now,
day 44. So give or take around half way.
Most of the ladies look ok, and all into flower now (FunkyM maybe not quite). The Jimmy Jacks is a bit droopy and not been happy since I did last feed but perking up a little, Blue Power came back to life but iss still being a bit miserable. I think she's very nute sensitive as others have had similar results from what I've been reading but we'll keep going, sure she'll come round.
The Spotless Mind seems to take anything I throw at her whilst the CannaCheese and Supreme Runtz are motoring along. And last but certainly not least...the Funky Magnifera is still coming on strong. She's now my new favourite...lol!
Anyway, here's some pics from a few days ago, I'll update with more over the weekend. Speaking of which, I hope all my fellow growers are having a relaxing and joyful bank holiday weekend.

I'm already thinking on to the next run and how I'll improve it with what I've learnt so far.
