week seven begins!

added 180 big fat ml of overdrive to the sauce. diluted down a little bit before adding it. ppm now getting up into the ridiculous range, but again, the higher it seems to go, the happier the plants seem to be, especially the OG. the lower fan leaves are fat and happy as they've been since mid veg stage.

topped off with 2.5 gals. this is about what the plants are drinking daily now.
adding 10 - 15ml of cal/mag per gal of top off RO as needed to stabilize ph.

again could be just me or could be it was gonna happen anyway, but not 10 hours after adding the overdrive all buds, again especially the OGs, look twice as glisteningly crystally sweet tasty good. maybe all in my head, but happy with the addition of overdrive so far.

have now added every additive i plan on dumping into the sauce, save some molasses. bought it, sitting here, don't know if i'll add it in or not. maybe for the final week.

bud stalks are leaning like crazy. cant really see it in the photos, but some of the taller stalks are leaning enough to consider staking them. gonna see if i can get away without it. if needed, might string up a little fishing line grid above the scrog screen. would be easy enough, could just run some string back and forth, anchored on the scrog screen strap supports.

but none of that is quite as fun as taking more cool zoom in bud porn.

yeah but nowhere really to stake those sticks. hopefully won't need to mess with it, but hell man, it sure is cool watching the weight pile on and stalks bend under it. got to be at least an ounce on the heavier ones, wet weight anyway.
in the long run, i might mod the cab to have a couple of eye hooks around 8 - 10" above where the scrog screen sits, on the left and right sides. could then stretch small bungees as needed like an X across the scrog area. something like that anyway. i hate making things out of fishing line or whatever stuff that will only work as a stop-gap temporary fix. i like solutions that continue to work and don't have to be messed with, cut out, re-done, etc.

get this, looks like we found ppm equilibrium at about 2370ppm of all places. was expecting to find this around 1750, really surprised to see it up here. Water level dropping fine, ppm staying about the same, good stuff. Probably not good stuff for the BD, but the OGs look healthier and happier than they have throughout all of the flowering phase. Still getting a particular shade of mustard yellow from the top down, but i can tell now that this is something to expect from an OG late in flowering, not a deficiency.

Dig the "crowns" popping up on the tips today. Is that the overdrive talking? i've heard it described before as promoting bud sites atop other sites. Don't know how true that is, but .. shrug .. there you go. Pretty cool. Crowns like this popping up today on probably 30% of the tops.

cut chamber one lights to 11 hours on as of today. also been letting temps start dropping down with constant venting.
despite nice equilibrium of ppm, begin ramping down with every top off.

crowns everywhere turning into pineapple top looking bud sprouts. overdrive fucking rules, im sold.
kinda funny. areas on blue dream that have been N deprived and very pale for weeks now are getting darker green again. guess it's finding N in the cal/mag? not much else in the sauce should be providing it.
some stalks leaning to 5" now. all stalks showing visible gangsta lean.

yep. planning on taking them to 70 days.

dig these pics of a clone experiment. had a clone catch the fuzz but continue growing with just the one fan leaf. it rooted pretty well, this is after ripping it out of the rockwool. its about 6 weeks rooted.

based on what i see here, i will scrape the outer layer from the stem tip next time and split them down the middle.

topped off. ph had finally dropped a hair. 4ml ph up and 12ml cal/mag after the top off, good to go.

calibrated ppm, was high again. crazy.

has been pretty cold in the mornings. under 55f in chamber one this morning with vent remaining on. no sign of any problems. timing is pretty good as daylight hours are reduced etc.
res temp has followed room temp and reached what, without going back and checking i think is a record low of 61f. i wouldnt mind this being a little higher but im sure it's fine. suppose it goes right along with natural fall temps and reduced daylight.

really loving the overdrive. buds forming atop other buds like a super mario double jump.

another small ph bump up today, less than a quarter gallon top off. letting it drop some.

Flush and fill with RO, @ 13 gallons

145ml each sensi bloom A & B
120ml unsulphured molasses
200ml cal/mag
100ml hygrozyme
75ml sensi grow B
200ml overdrive

I don't like this blend at all but I was short on sensi bloom. If i still dont have a good feeling about it tomorrow will flush and go pick up more sensi.
dont know if molasses was a good idea or not. it made the sauce a little frothy, hopefully that calms down.

ph up as needed

See above recipe.
Note to self: Don't ever do that again.

Sauce looked more like fucking gravy. Molasses is fired. Maybe it does nice things, but my res looking like it's full of coffee just fucks the feng shui.
Frothy is the hygrozyme talking, not the molasses. Next time i'll add it gradually. Hopefully the froth isn't a problem. Probably done this every time and I just haven't noticed.

Flushed again, @ 13 gallons RO with:

220ml each sensi bloom a & b
100ml overdrive
100ml hygrozyme
ph up to 5.8
185ml cal/mag

this is the last dosage of nutrients that these plants will get. the last meal.

also calibrated ppm. meter was fine this time.

ph 5.8, 1740 ppm, 72f res (RO from different machine, 10f warmer than the other machine.)

chasing ph again but should have it nailed down by tomorrow. i underestimated the amount of cal/mag to throw in. probably double it and then some. have added another 65ml over the course of the day.

ph 5.3 this morning, about 7 hours after last entry.
maybe triple the cal/mag next time.. seems ridiculous now.
I WILL get this nailed down.

edit: LAUGH
5.3 again not 4 hours later. Everytime I think I have this figured out ..
no time for chasing PH today. dropped in 3/4 tsp baking soda.

after harvest, res gets fitted with a circulation system. really wonder if im dumping stuff in on one side and it's not making it to the other side due to root mass in the way. or making it slowly. something.
