Time for an update!
As usual all of the plants are doing extremely well and starting to suck up so much water I may need to shorten my res changes to 5 days, or add additional water and nutrients mid week. Based on my last calculations each plant is drinking 1.5 gallons a day which depletes my 40g res rather quickly.
It is almost like these ladies are daring me to overfeed them, so I went ahead and cranked everything up with this last res swap. I am now running the AN Bloom formula at 115%. I do not even have the slightest sign of burn on any leaf, and it looks like the minor phosphorous deficiency I saw last week corrected itself with a higher dose of Bloom formula.
Prior to reloading the res with new nutes I ran clearex through the system for an hour to remove any salt residue.
Current Res Mix
140L - Tap Water at PH of 7.4 and PPM of 17
150ml - Calimagic
300ml - AN Grow
500ml - AN Micro
650ml - AN Grow
175ml - Bud Candy
175ml - Big Bud
175ml - Bud Factor X
50ml - Mammoth P (my new favorite bennie)
This brings me to
1650ppm, 70 degrees F, PH @ 5.9
I have cut out the great white at this point to see exactly what this Mammoth P is made of. I have also started to foliar feed with Bud Factor X every 3 days immediately before lights off. I have already noticed a spike in resin / trichome production and all of the plants have an "oily" feel to them. Aromas are finally starting to show themselves but nothing spectacular yet. The Blue God, Grape Stomper OG, and Deadhead OG x Sourband are very sweet. The Amnesia Haze has a spicy and piney scent very reminiscent of Golden Goat.
I also began to give all of the plants a rather serious defol today which has really opened them up and revealed additional budsites.
..... I started to count colas today, and gave up when I hit 100.
........
Here are a few shots out of LED light about 80% through the defol. I still have a few leaves to remove but I am going to give them a day or so to recover.
I also took some time to look at my current ventilation system and made a few improvements. I am now running 460CFM out with a 260CFM booster fan 15 feet down the duct into the crawlspace below my grow room. This has been tremendous for temp regulation and I am now seeing 77F lights on, 65F Lights off.
I still have the ability to dial the heater down at night when it is time to let the plants build up some color.
That's all for now!
