Before hand i watered the soil upto the point where it released a couple of water droplets when i squeezed it, so that the soil doesn't sink back to the middle of the pot, so it's 3/4th filled.
I dug a hole in the middle of the pot, filled it with cutting soil, aswel as a layer of 3cm ontop of the current substrate.
The substrate itself has been enriched with organic fertilizer made out of cow manure by DCM, and kieserite (26% MgO) both half the prescribed amount.
Discovered fungus gnats in my tent, so i bought some nematodes to eradicate the gnat's larvae and yellow catch-plates with pheromones to trap them.
The first signs of calcium defficiency starts showing on the first bottom leafs, i ordered BioBizz calmag, but only got it the next week.
I added calmag when i received it, 0.8ml/l, afterwards i continued to water with 0.3 per watergift, THIS WAS A MISTAKE! Apparently you should only add it once per week, because i gave to much, the plants started to dehydrate, because the soil got more salty, and in turn, sucked water out of the plants, instead of the plants sucking water out of the soil, due to osmosis, and that nature will always try to balance the amount of salt in connected spaces, by adding more water to the higher concentration, so it will lessen.
I counteracted this by adding rainwater to the plants, close to 2l per plant, sucking up the water on the bottom, aswel as moving the plants into a bigger pot with fresh soil filling up the new crevices.
no nutrients were given afterwards due to the large amount of nutrients from the previous days, i will continue with my feeding schedule within the next week, also thinking about putting them on 12/12 next week, depending on how much the top shoots develop, i would like 3 nodes atleast.
On the night of 28th-29th i put the schedule on 12/12. I intended on giving the grow fertilizer for the last time, depending on when the first buds start appearing, but after doing some research i have read that it would be better to give 3 weeks of growing fertilizer after setting the light schedule to 12/12. So i will keep on doing this until the week of the 13th febuary.
The reason for this odd mixture of nutrients is because of the constatation of a low pH, all the pots have sunk down to a pH level of 5.5-5.7, because of this certain elements like P, Ca en Mg, as well as N in a modest amounts start getting less available in the soil because it binds to other compounds, which the plants can't take in.
I wasn't too sure of what return rate the nutrients would have when the pH started increasing again, because i first thought the necrotic spots were signs of too much fertilizer, instead of the low pH, so i watered extensively, which might in turn have rinsed out of lot of these compounds.
Seeing that the major deficiencies were P and K, i decided to reintroduce these compounds in the soil. Adding plagron pH plus as a one time addition, will make the soil a bit more alkaline in a shorter time span than normal tap water, i added a modest amount of all of these fertilizers (1/4 to 1/2 of the recommended doses. expect the pH plus) to ensure the plants don't stress too much.
The addition of this mixture was on the 9th of febuary.
So far the necrotic spots have been reducing daily in expansion rate. It seems like the low pH was the cause of the P, Ca and K blockades, it bothers me greatly that i picked up on this so late, and that my girls are in this current shape.
The pH in the middle and lower regions of the pots are still around 5.5 to 5.7, the upper layers seem to have a rather high pH, i assume the more i water, the more of this pH will start going down in the pots and in turn raise the pH in the lower regions, as well as reducing it in the higher regions of the pots.
I'm planning on giving grow fertilizer for the last time in this coming week, while doing this i will measure the pH of the water, and add pH plus if this is necessary.
The roots of the girls don't seem to be having any problem with the 1.5ml of pH plus i gave previous week. they appear white and healthy in the top layer of the soil.
Hey
The pH is slowly creeping back up to the desired 6.5, the upper and middle part of the soil is currently at 5.9 pH, This will be the last time i will give grow fertilizer, the girls their leaves are slowly getting more and more green, which is what we like to see. Apart from that there isn't too much to talk about, only that my light wasn't set up perfectly straight and my right sided plants got more light than my left ones, i fixed this issue, also the purple queen on the right is showing very nice purple coloring in the buds.
The pH is slowly climbing back up into the 6, the fan leaves start getting a bit more greenish, while some of the heavy damaged leaves started to fall off, i assume this is selfpruning of the girls.
A lot more hairs got brown and the calyxes are nicely stacking up.
There are still new hairs being produced, so they'll swell up even more, which is a good thing.
We'll see how fast all the trichomes develop but i reckon it will take another 2-3 weeks at best, but by all means the longer they keep swelling up, the better :P
Nothing much has changed tbh, they're slowly blooming their way to those juicy amber trichs.
They still make new calyxes and they'll swell up a bit more, within 2-4 weeks it should be good so i'll give one or two weeks fertilizer and then only go with water from there.
A bit harder to get the air humidity under the 50% because it has poured down quite a lot in the recent days, atleast it's back to 44% atm which is very nice to prevent budrot.
The air humidity spiked today when i opened my tent at 58%, which is far from optimal, i raised my humidity sensor up into the foilage and it showes 50%, which is not optimal but it's within the acceptable range, previously i had it around the bottom of the tent.
I cleared some leaves to expose the hidden buds underneath the canopy as well.
I think i'll harvest the weekend of the week to come, since they'll have had 2 weeks of only water by then. since i give fertilizer on the sunday, and i gave the last fertilizer on the 10th.
The critical, top right girl is ready to be chopped this sunday, it displays 10% to 15% amber on the upper buds, the other girls still need a week, the bottom and side tops still make new hairs and the trichs on the bottom buds are mostly cloudy and clear.
they've gotten only water for 1 week and 3 days.
The critical has been cut at 24/4, the purple queens require another week since the bottom buds were still clear/cloudy with no amber.
I've done a test to see how much the taste and riping of the trichs will change while drying with or without sugarleaves and wether or not it makes a difference if it's still on the stalk or if the twigs is cut off.
This is the last week for the queens, i'm kinda debating whether or not i should stop giving water in the last week, since a buddy of mine said that they get some sort of boost, since they make an extra effort to produce offspring.
Took quite a bit of time to dry since the humidity was around 50-60%, i checked daily on mold but we got spared luckily! :D I've also been quite busy so i couldn't really maintain them a lot during the last week.
@BleuBayouOrganics, Yeah i was thinking it aswel combined with P and Ca, but what is actually happening is that my PH went down in my soil from 6.5 to 5-5.5 somehow. and this blocks Mg Ca and P from being absorbed, Which is the reason of the discolouring. I first thought it was a deficiency aswel, but as it turned out without me noticing, it was because of this that the nutrients are getting blocked from being absorbed, and it seems like there isn't enough in the ground, but i can assure you, there is plenty, a bit too much actually, next run i will start using feeding schedules and go full organic, with the exclusion of pk 13-14 in the last weeks. That way i wont have to bother with PH anymore :)
