New Grower Auto Ultimate and Auto Blue Amnesia XXL Grow Journal

[PermaFrostPete]

@912GreenSkell thanks for the info mate, was thinking of LST'ing once the stretch starts in a bid to keep them down. I have plant training tools called "bendz" from one of my local hydro shops which clip onto the stalks and bend them 90 degrees, I'm a little scared of damaging the stalk though lol!

My biggest concern at the moment is pH'ing my water. Before nutes my tap water is pH 8-8.5 and after nutes is normally pH 5.5. I heard 6.5 is perfect for soil grows. The company who makes my soil and nutes say don't pH before watering. I have been pH'ing it to 6.5 anyway (with potassium bicarbonate, trying to stay "organic") but I'm not sure because of the conflicting views.

What do people think about this?

Ultimate Day 30, Blue Amnesia Day 24

Hi guys and gals, it's time for another update. It looks like the BA is more mature than the AU currently even though the BA is 6 days behind the AU, so it seems like the AU could take longer than expected as @912GreenSkell mentioned.

Watering 3L of water for each plant every other day, and giving the max grow nutes suggested by the nutrient companies schedule for photos, and they seem to be liking it as far as i can see. I defoliated a few middle-to-upper fan leaves on the AU to try and open it up to more light (probably around 4 leafs since the last update). I will be switching from MH to HPS at some point, but I'm thinking of waiting until after stretch to try and keep the plant height down.

Watering 3L of water for each plant every consecutive day, and giving the max grow nutes suggested by the nutrient companies schedule for photos, and they seem to be liking it as far as i can see.

Ultimate Day 37, Blue Amnesia Day 31

Hello people! The blue amnesia smells deliciously berryish! Still watering 3L but changed to bloom nutrients when the ultimate was at 35 days and they had both been showing preflowers for around a week(not sure if it's right time to switch). I'm planning to start watering a lesser volume but daily, instead of every 2 days. I've sat the ultimate on top of a box to even the canopy level.

My RH was very low at the start of the grow (and for the entirety of my last fail grow), around 20% so I'm suprised they took off the way they did. The RH is now approaching 50% and is going to rise more I guess. Temps over the course of the grow have been 24-27C at lights on and around 18C at lights off.
Some of the leaf tips were slightly burnt on the ultimate when I was feeding it max grow nutes, so I'll take it down 0.5 ml/L next grow if i do the strain again. The blue amnesia seems to be able to eat more. Is this because of more sativa-ish genetics?

Looking good. 50% to 65% humidity is ok at this stage, you will want that around 50% in mid to late flowering. Really it would be good to learn about VPD (a good place to start) and I have a calculator spreadsheet if you have excel? Download it here: http://jmp.sh/rMmC4Oy To use the calculator you need a laser thermometer to take your leaf temperatures. Test several locations and use the average.

Different strains and even different phenotypes within a strain will respond differently to nutrient levels. I usually start around 50% strength and keep raising it until a little bit of tip burn then back-off 10%.

Thanks for the links, looks like really useful information. It's the first time I have read about VPD. I'm pretty poor at the moment, but will definitely look into getting a laser thermometer next run.

I found what looks like a nutrient deficiency today in 2 places on the ultimate at the top leaves of the canopy next to 2 flowers (not on the highest central cola though). Am I right in thinking this is a calcium deficiency? I have magnesium, but no cal mag until Monday, with one feed due until it arrives (on Saturday night). I'm guessing giving mag would just upset the imbalance further if this is the case? I've fed mag once at 1g per liter on day 25 and switched to bloom nutes on day 35 (on day 38 now).

Calcium deficiency? Yay or nay?

Yes looks like Calcium Def. but could be light burn also. What kind of lights are you running and how close?

Thanks guys, @Mañ'O'Green at the moment I am using a 600W MH dimmed to 400W and a cool tube at around 8 inches, it doesn't seem to feel too hot on my hand but I could raise it if it is recommended. I guess a bit of cal mag won't hurt it anyway.

Cool tubes did not exist when I used MH(35 years ago) , in fact I don't remember being able to dim it either. I think that is too close but we need someone that uses MH nowadays to chime in here. @Ripper @Waira you guys using these or know somebody that does. I remember the hand test but I don't know how a cool tube might affect the outcome of that?
