My own super soil mixture, lightmix with biobizz premix, blackearth, hummus, guano, mycorhize, startrex (microbes from biotabs), ...
Watering by spray or 1 dcl water
outdoor temperature 16-22°, RH 30-70%, I hide it under a plastic container to increase humidity. I am slowly teaching her to the outdoor environment.
I think that the soil is maybe little bit ,,living", i had nute toxicity on three leafs,
two from them i cut and everything is ok, she will be fine.
Top was OK, i have two new main colas, i started with LST.
What i did this week: transplant to the final smart pot 20L with new fresh supersoil. Tying the branches and opening the canopy.
Continue with pure water, add silica this week.
Everything is well, i continue withou problem. Nothing to do this week, only watering. Good weather this week, not too hot. Temperatures are about 28 at day and 18 in night. I wait on flowering start. Iam nearby.
I bought some new stuff in my local growshop, worm hummus and leafcoat, both from biobizz, and new kilo guano powder from guanokalong for bloom.
I'm ready on flower stage.
i used some liquid fertilizers, because my bottom leaves started yellowing and a week after using topdressing with worm hummus didnt help. I used biobizz biogrow. I made some super cropping and removed some weakness branches on the bottom. Its about waiting for stage now..
More water, more ferts, still some yellowing, but still grow up. I will change some things, i will go with PH down on 6, cause my run-off water is ph 7.8. This is maybe my problem with yellowing. Iam little bit nervous, that shes still not flowering. Today is 11.8. and ammount of light hours is 14 and a half hours, but on the eve ing is sun behind building, a day for her is shorter for 2 hours.
I read about it, it can be good or bad.. what do you think? I am now trying to solve the PH problem, but nothing urgent. The question I don't want to read is "control your PH" I'm asking about the red color on the branches.
Can be genetic, can be phosphorous related, either not enough or too much......... I have had this a few times in the past and I do not think it affects the plant greatly.............generally genetic related, often in Sativa dominant strains.
I would not be too worried.
A lot of people make a big deal about stem coloration. Alone it's largely meaningless. If coupled with other issues it MIGHT help point you in the right direction regarding deficiency. Looking at the condition of your plant, I wouldn't stress it.
I have soil with dolomitic limestone, I did not know that it reacts with citric acid and increases the PH. Paradox: the more acid I add, the higher the run of water. My solution: replacing the acid with phosphoric acid and adding ammonium sulfate and flushing?Any other solutions?
not how acid base reactions work.
you don't need to use citric acid. if you feel that is a cause use something else. I'd wager that the issue continues. could also be related to your ratio of nutes used in fertilizer. if certain ones aren't at critical levels around roots, the active transport occurring will deplete it and uncontrollable or difficult pH issues can result.
h30+ + oh- = 2h2o - the simplest "AB reaction" in an aqueous solution. The result is 2 pH neutral water molecules and not ever "more" free hydroxide (proton acceptor = base) ph is the log scale of h30+ to oh- ratio.
if you have way too much garden lime, that's more likely to cause what you see. Every promix bale i've used has dolomitic lime in it and have no problems with pH drift or major shifts. simply doesn't happen in 6 years so far. if you self-amended above and beyond, reconsider that step.
Ok... so... what I did this week... I moved the plant into the shower and flushed it straight out of the shower. Lots of water. The first runoff was 8.5, I managed to get to 7.9 by flushing. It couldn't be less. So I visited my growshop and bought PH - from advanced hydroponics with phosphoric acid, because the citric acid from biobizz was messing with my PH and EC. I don't have an ec meter, but I had to use a lot of citric acid and it changed the values in the substrate. So I watered with phosphoric acid treated water and managed to get the substrate PH between 6-7, closer to 7. I will continue with PH 6 water and see what happens. After three days i saw the improvement, the yellowing has stopped and the green has returned. I'll see what happens next, I'm just before flowering. 14 hours of light a day and the days are getting shorter.
Stretching is in progress, this is definitelly last veg week. Next week start bloom phase, but i dont know if i will go back with liquid nutes or continu with pure water and guano.
I still have some problem with yellowing, i start with liquid fertilizers and i choose products from Plagron. On the last minute i decided to make a DIY SCROG and cut off all yellow and weakness branches.
.oh my god my ph meter was off the whole time. yesterday I immersed it in a solution from milwaukee with ph 7 and my meter showed 8.5!! This is the source of all the problems with this growth, meaning I was using water with a PH around 5!! I should have checked the ph meter at the beginning of the season, it's too late now. One learns from mistakes, and this mistake taught me a lot for the future.. test your ph meters regularly!!!.
Last fertilizing this week and then i will continue with pure water. The finish is nearby. Weather is good in this and next week.
You can see a lot of trichomes on flowers, this is fldefinitely due to the low temperatures at night, but Purple shades do not appear.
LAST WEEK !! Iam so happy that iam on the end of this way.
It's been hard, but I'm done. I will wait the last few days and harvest at the end of this week. I plan to wash the buds to get rid of all the crap from outside, dust, bugs, pollen, contaminants.
Big plus - No mold!!!
I smell diesel the most, I don't smell any fruity or lemon notes. It doesn't even resemble cheese yet, we'll see what happens after harvesting and washing the buds.
I made a lot of mistakes in this growth and therefore i will not be doing a review on this strain. I had problem with PH, but my ph meter was off. I am glad i am over..
I wash buds in water for the first time ever, looking good.
