She is shaping up nicely! I’ll have to grow one of these beauties! 👌

Day 36:
We are the 12th of september 2023
Today is the day the magnesium deficiency/lockout problem starts to appear the most, this is 1st because I got a shitty calmag from biobizz, and my calmag from canna was lost in transport..
and two because my pH is so volatile, so I need to correct the two problems asap..
Day 37:
We are the 13th of september 2023
230 EC epsom salt (magnesium sulfate) added, to destroy the deficiency
1.5ml/L calmag & 1.33ml/L A+B
input pH 6.1
input EC 1126
input ppm 560
weight before: 1.5kg; weight after: 2.35kg
output pH 5.68
output EC 1176
output ppm 589
Chlorosis and red-stemming still occurring, I think I did not water enough until now to know the true runoff pH, I am now REALLY running off the water to get the acidity out (future me: this input pH should be 6.5 or more to readjust up incase of lockout, I think the lockout is really happening ffs)
Day 38:
We are the 14th of september 2023
Weird artifacts on the leaf reminding me of thrips, got out the jeweler's loupe but there doesn't seem to be ANY trace of living beings on here.. we'll see I guess.
Day 39:
We are the 15th of september 2023
320 EC of epsom salt added for the deficiency
1.46ml/L calmag; 1.33ml/L A+B
input pH 6.5
input EC 1170
input ppm 583
weight before: 1.7kg; weight after: 2.35kg
output pH 5.82
output EC 1045
output ppm 523
Day 41:
We are the 17th of september 2023
641 EC epsom salt -> 1.16ml/L calmag ->1.33ml/L A+B
input pH 6.48
input EC 1398
input ppm 698
weight before: 1.35kg; weight after: 2.35kg
output pH 5.66
output EC 1226
output ppm 614
I applied a foliar spray of Magnesium sulfate at 2% conc (10g epsom salt/500ml distilled water)

Grow Questions
Dufftwtstarted grow question a year ago
My tap water is at 700EC (very hard), and I add nutes normally until around 1000EC, which gives little room for nutes, if I replace with distilled water, can I go up to 1000EC with it ? (gonna be a LOT more nutes).

My tap water is around 300-350ppm or 0.6-0.7EC I will mix my feeds up in it and have no ill effects. its on the lower end of hard water if you place it on a scale vs others.
Hardness of the water is not judged by its PPM count but more so how much of the mineral content is calcium and magnesium. Other things can influence the EC of water but not make it hard.
Distilled waster will have many more available nutirents vs tap water when both are at a EC of 1.0 or 500PPM if using the 500 scale.
If tap is .7 that only leave .3 of fertilizer to make 1.0EC
but 1.0EC in distilled "0.0" is 3.333 times stronger as theirs no base charge like in tap water "0.7", and with liquid fertilizers they are totally available to the plants where tap water has compounds that will not affect the plants right away as they need to be broken down first. So you could run the risk of overfeeding in that setting.
Best Of Luck!
Dufftwtstarted grow question a year ago
I remarked that my plant grows much faster when I leave a day in between feeds, but that's not applicable to every plant, and I want a sure way of knowing exactly when my plant needs water(using coco coir/perlite, I'll answer more in replies as there's a limit of chars here)

watering is reactive... you react to the outcome.
you are soilless so it's even simpler.
fertilize every single irrigation around 1.3-1.5 EC. ratio/balance is obviously key, so you'll have to work that out over time.. observe and adjust.
in coco, wait for top layer to start changing colors, and it's a good time to fertilize again. If the plant drinks fast, more frequent fertigation is possible and you do realize additional growth from that method. I'd suggest forming a good baseline doing it a safe and conservative way first, then you can more easily assess whether any risks of doing it are worth it or not.
you need at least 33% loss of water weight before you fertigate again or you'll just drown the roots or increase risk of infecion in roots. i wouldn't do this early on in life. a larger more mature plant or as you go into bloom, sure. I'd rather i grow my roots early on in a way that makes them grow deep and aplenty. roots follow moisture in a reactive way. you get fewer superficial roots (at surface they become useless if exposed to light) by having a good wet-dry cycle. the top will always dry first.
if you want to do multiple fertigations a day or water when the pot is only lost 33% of the water you previously gave (can feel the weight to judge), wait until the plant is a bit more mature or flip to bloom.
growth is a curve. it's slow at first. these sort of things help, but not nearly as much later one. it's worth the small loss for improved root growth early.

There's chlorosis between the veins and red stemming, indicating a magnesium deficiency, however both calmag and alot of epsom salt (EC is within target dw) were used to fix the deficiency and it seems to still be progressing, is this lockout ? more info in the answer to this

Could be lockout, to help identify your deficiency issues I recommend reading this blog https://futureharvest.com/blogs/articles/how-to-identify-cannabis-nutrient-deficiencies?_pos=1&_sid=f81d0e725&_ss=r
Because symptoms often progress even after applying a curative approach I'd just make sure you are following your nutrient schedule keeping EC around 1.2-1.5 or so and maybe go easy on the epsom salt. Often times its a good idea to flush the media of nutrients with alot of water and then just introduce calmag to your regular feeding schedule. Lockout can occur too when a plant's environment, watering regimen and temperatures are out of whack. Coco coir can be slow draining so make sure it dries out before each watering. Hope this helps! -Bryce from Future Harvest Nutrients

@James, Thanks a lot man! This is for sure gonna be an awesome grow, this is one of the most resistant strains I've come across somehow and I just love it so much. How long do you recommend for veg/flower for this strain ? I want a decent yield from this girl

Questions: did you use a dome or baggie for the humidity at all? Of so for how long should I cover my seedling for, it's about 2-3 weeks old now, do I still need to cover it? Mostly growing on my windowsill but I have lights too. But does it still need a cloche?
