3 week (day 20) update
Topped up to 600PPM and applied 3rd dose of bennie tea today. I'm going to go with a res change every 2 weeks unless I spot something dodgy going on I think. That way I can coordinate brewing tea with my res changes.
Roots looking good:
They have that shiney fish bone quality going on. Also look hairy in places. All very healthy I think
Here's Pineapple Express day 20:
And here's the veg room:
You can see there are a few plants that look a bit smaller as they were set back about 5 days when the root rot hit compared to the ones which kept growing. Only 1 of the Purple Afghan Kush plants got really stunted and is about 10 days behind it's sisters at the moment. You can see it's the one on the Left row, third one up.
I have some rhizotonic which I'd bought as it was recommended by Canna's guide... not going to be using it anymore as I wonder whether it was partially responsible for the root rot? Possibly not. Anyway I decided to use it as a foliar spray instead. Have given the stunted plants a couple of sprays today and will keep doing it until they're really back on track again.
Also have done some work on the mother room. Put up some celotex as internal walls. Sealed up the edges with my fave... expanding foam!
Have mounted a 4 inch fan and carbon filter in there. Hooked up a 10 port extension and hung a 2x55w T5 light fixture. Only waiting on another small section of pond liner to arrive and I'll seal the floor. Then I have a 6 pot autopot to take care of the mother plants. Going for a 60% coco/40% perlite mix. I'll only need about 4 cuttings from each mum every 2 months max so I'll be aiming to keep them really small.
Once the mother room is completed I just need to apply some finishing touches to the flower tents and I'm all "done"!
Think a 5 week veg would be reasonable? Gives me 2 weeks to fanny about "finishing" things.
