Ciao! This is my second growth ever and second time growing Glueberry OG auto. I don’t have much space to grow into, I can only use my washing machine closet which measures 50x60x110cm total. Adding all the equipment I have 50x50x90cm of true grow space. Since I don’t want to constantly grow to satisfy my needs I have to optimize everything!
During my first crop I spent a lot of time studying and changing my growing environment and plant nutrition, this time I will focus more on plant structure. I plan to mainline the trunk and to apply LST during vegetation, than let the plan grow as much as it can.
The big thing you can see in the pot is a blumat carrot, automated dripping system. I’ve already placed it not to disturbed the roots once grown but I don’t know if I’m going to use it since I’m in lockdown...
During vegetation I will give every watering a splash of humid acid + seaweeds + amino acids and megacrop.
Megacrop is the best nutrient I could find in my research and during my first grow proved its power. It has, however, too much nitrogen for flower and a low quantity of silica. I’ll supplement silica with rhino skin by advance nutrients, and during flower I’ll switch to megacrop 2parts so I can control the nitrogen. I have a general roadmap for nutes based on my past growth!
My tap water has ph 7.4 so I need to lower it a lot. My acid of choice is sulfuric acid, this may seems strange but it was a major breakthrough during the first growth. You need just few drops per liter, it’s super stable once well mixed and gives sulfur (FUCKING SULFUR) to the plant, it’s win win win. It costs nothing and you find it everywhere, I’ve bought a scooter sized battery recharge for 6€, and it will last A LOT of grows. The only downside is the danger of having a strong acid at home, don’t play around it.
I’m growing in a 11 liters fiber pot, half full at first because I’ll be adding more as the plant stretches. Using this method I am able to gain at least 10 cm of vertical space.
I won’t transplant. Transplants are bad, m’kay?!
Medium is 100% coco, very well washed, and I mean VERY WELL washed. I thrown away like half bag of dust and minuscule pieces!!
Coco is buffered with Epsom salts and gypsum, along with all the nutrients I’ll be using during growth. I’ll do the same thing for all the coco I will be adding.
The white stuff it’s a little sand I used in a previous strawberry crop.
The plant is placed on top of my washing machine so a couple times a week it will receive a good dose of shacking. This was a thing I was scared by at first, but than I found out that not also the plant doesn’t really care even during germination, but it can have positive effects on buffing trunk and brenches.
Day 20 - Topped at the third node. I also cut the shootings of first and second node.
Second node’s leafs look like a nitrogen surplus landfill, I find that very usefull so I decided to keep those a little longer.
I’ve added more coco in the pot, just enough to almost cover the cotyledon.
Note from future me: it’s not N toxicity but calcium deficiency and it will be a thing I won’t understand for a very long time
Temperature is really high 32C, a couple of leafs started cupping. Soil was a little too dry for a day. I’ve installed a little humidifier in the closet and set it at 50% at first not to stress the plant with a high jump in humidity.
I gave 1ml/L of silica (rhino skin by AN) to help the plant with training and temperature stress.
In the last day of the week I did some defoliation, it was needed, lots of new leaf are coming!
I noticed the plant is growing stronger on one side than the other.
Day 29 - Plant is drinking a lot more, growth is speeding up. I’m going to increase megacrop feeding.
I defolieted 2 days ago, can you believe it?
Day 32 - starting to smell something
Day 34 - I’m balancing the canopy using LST, I’m also cutting small shootings. The two top are stronger than all other bud sites, for now I just bent those more aggressively.
Day 35 - I’m done tying branches, I’ll continue to balance the canopy adjusting the ties, for few more days.
One of the strong tertiary branches was in a weird position and I couldn’t tie it the the pot. I didn’t even consider to cut it so the only option was to let it grow free as the now top. I hope it will stop the plant to deliver so much energy to the 2 true tops.
First pistils are out and stretch is coming, I’m increasing nutes.
I found small damage on few leafs, probably related to the silica supplemented last week without ph correction.
Hi! I found small damage on 4 leaf.
Could that be a genetic mutation or damage I did while doing LST?
I have everything under control regarding environment and nutrition, this is the second time growing this strain.
I have no clue ?_?
My instincts says genetics..
Thanks!
Ph at 6 is the max in veg for soiless. At this point you can start getting a few little leaf deformation. Bring your ph to 5.8 the sweet spot for soiless in veg. 6.2 6.3 in flower. Cheers
Preflower just kicked in, this week I’m still feeding high nitrogen since branches will stretch a lot.
I don’t have much to do now, other than don’t screw up, I just have to water before light off, and maintain a balanced canopy.
Day 38 - I’m smelling a light fragrance of berries.
I’ve PHed the water slightly acidic, like 5.6/5.7, I’m curious to see how the plant reacts.
Day 39 - spotted a couple of young leaf twisting. Watered at 5.8 ph and less N today, leaves are dark dark green.
Day 40 - smell is leaking out the room where the closet is in, I’ve turn on both carbon scrubbers. I f hate the constant background noise so much, even if it’s barely audible outside the grow space.
Canopy is now 45cm from lights.
Temperature in the closet is high today max 32C, I’ve set humidity to 70%. Megacrop 2parts arrived, I’ll start using it when switching nutes for less N.
Day 41 - odor control is working as expected. Temperature is still high, a little over 30C, with 65% humidity. The plant looks very happy. Feeding megacrop+magnesium to boost N intake. I’m switching root juice (humid acid) with top max (humic+fulvic acids), I should have done this weeks ago but I forgot about it.. that’s the reason I’m keeping a diary now!!
While watering I understood that I needed to lower the lights to help the inner canopy burn all the nutes I was giving. Distance from canopy was 42cm, now is 35cm.
From past experience I now that the plant can stand much closer to my lights, but I don’t want to drop it too quickly, I’ll see how leaves reacts.
Jungle is growing on top of my washing machine! On the last day of week 6 I lowered lights to 35cm from canopy, this week I’m going to monitor that number and adjust as necessary because the plant is still in stretching + bud setting phase.
I’m feeding with high N+mag and I’ll continue until growth slows down, than I’ll switch to megacrop 2parts. I expect that to happen end of this week, 10 days max.
Day 42 - changed the fan
Day 44 - finally installed the blumat auto irrigation system. It wasn’t that easy since branches are really near the substrate but at least I had the carrot already placed so I was able to do it.
High frequency fertigation on coco is a must, you can’t take advantage on coco great qualities watering 1 or 2 times a day. My system has 5 drippers placed in a Pac-Man shape, more or less.
Day 45 - This is an important day since it marks the halfway point of this crop, based on my previous results. Coincidentally I’ve also spotted few small trichomes on a leaf, I guess the plant is now ready to build up mass and flavors. I did a minor defoliation to open up the inner canopy and to get rid of some plant’s nitrogen reserve.
I prepared 20L of my bloom solution and mixed that with the veg solution in the reservoir. For a week I’m going to use this transitional feeding. Lots of sulfur, seems to be on a volcano 🤣
Day 46 - spotted a minor P deficiency. There is probably too much calcium in my solution that is antagonizing P absorption.
I mixed another batch, this is the ppm breakdown
N 100
P 100
K 280
Mg 85
Ca 150
Before I had P 40 and Ca ~190, my tap water has 80ppm of Ca that is already counted it.
I’ll keep this value for a couple of weeks than I’ll lower everything except K.
(Edit from the future - K is too high)
Day 47 - plant looks happy and bigger, it drunk 3+ liters yesterday.
There is no need for humidifier anymore so I’m getting rid of it. Temperature is 30-32C with 50-60% humidity.
Day 48 - buds are swelling, some branches are already showing the spiral structure. Plant drunk 5 liters yesterday, impressive.
I’m starting to use mega crop 2 parts but I’m modifying it to my needs.
This is the list of salts in the mix
Magnesium sulfate, calcium sulfate, potassium sulfate, MPK and silica dioxide. Plus sulfuric acid to balance PH.
As you can see I’m using lot of sulfur, my nutrient solution smells like thermal water from volcanoes.
Today I spotter some leaves’s with brown tips, It’s probably still related to P deficiency. I’m going to lower K since it antagonize P absorption and last week was so high that could have caused minor toxicity.
I’m also flushing just to be safe there are no salts buildups.
Here is the PPM count
N 90
P 100
K 240
Ca 160
Mg 90
S 113
Si 22
Day 50 - yeah I’m probably having K toxicity, I found more leaves with black tips, I hope the wash I did yesterday + lowering K in this week feedings are enough to stop the spreading.
Day 51 - looks like damage on leaves is progressing very slowly. I have refilled the reservoir with ph water, the plant is receiving a ~25% less stronger feeding now.
The smell is sooooo very good!!
Day 52 - damage is spreading on more leaves.
I lowered lights by a few cm, maybe the plant needs more energy to burn all the nutes.
Day 53 - damage is spreading today too, I’ll add more ph water to the reservoir to lower my nutrition solution to 50% strength.
Day 54 - plant seems fine, I can’t see new damages on leaves so I’m going to start feeding again with megacrop (less N) magnesium and silica.
Day 55 - huge ph swing for a couple of hours, plant is drinking more.
Last week I had problems mixing my own nutrient solution but the plant is growing nicely anyway!
Day 58 - few leaves are showing signs of k deficiency. I’ve refilled the reservoir with suggested full bloom dose of megacrop A+B +epsom+silica. I won’t try to substitute part of megacrop A with potassium sulfate anymore, I feel I have enough sulfur just with epsom&acid. Since I’ve start supplementing silica dioxide I’m using much more acid than before!
Day 60 - clogged drippers. Pot was still wet so plant had no damage but my hate for blumat drippers grew again.
Day 61 - raised lights a little, some of the smaller top leaves looks burned
Day 62 - I’m filling up the reservoir, same solution as last time with less megacrop part B (less N and Ca).
Plant is drinking almost 5 liters a day.
Smell is potent, I suspect one of my filter isn’t working properly.
I’m feeding megacrop A+B full bloom +epsom+silica. Not much else to do.
I expect the plant to be ready in 20 days, more or less.
Last week I raised the light a little since I found damage on top leaves.
I think I’ll change pot next growth. I’ve calculated that a bonsai style pot, bigger and shallower than my actual one, would contain at least 3 times the volume of medium.
Day 64 - Damage is spreading on all small top leaves, I guess these were not frying because of lights. A full dose of megacrop it’s probably too much for a plant watered with a dripping system, I’ll keep than in mind for my next crop.
Day 65 - Plant is drinking like crazy, yesterday it consumed much more than usual, almost 9 liters. I’m going refill the reservoir today with megacrop AB+epsom at 2/3 of the suggested dose.
Day 70 - I found out that one of the bud was rotting.. and looking for more rot I found PM. What a wonderful day!
I’m going to harvest earlier and wash everything GD
Day 71 - No new signs of rot but I bet there is PM inside buds, I’ll let the plant mature one more day, tomorrow I’ll harvest and wash everything.
Hi! Yesterday I found out that one of the buds was way dryer and more brown than the other.
Is this bud rot? Plant is almost ready but this bud looks way different from the others
Sadly yes, rot. Try removing all traces of it from your living plant, in the areas where you found this bud. After that, wash your hands thoroughly and look for any other sites that may also be mouldy and if so remove those buds too. Always wash your hands again if you find some more before touching anywhere else to look further. You may have to increase air movement in your tent to reduce the humidity as much as possible. If you have caught this early enough, the rest of your flowers should still continue maturing as normal. Tell tale signs that there may be some rot in your buds is that the leaves associated with that bud will have died or look as though they are dying and in worst case scenarios, branches will fall over/break, due to the mould eating all the way through to the stems. Also caterpillars can sometimes burrow into the rotten buds, so look out for these too. After looking through your diary, I noticed a lot of burnt leaves, too many nutrients I would say, and these burnt/damaged leaves show signs of mould "attack". Another thing, 70% humidity or levels that high at any time is going to cause mould problems. Cannabis is not a rain forest plant and really doesn't need any auxiliary humidifiers in an enclosed grow space. Switch it off ASAP, your plant won't mind, plus you will save money. Hope this helps,.... Organoman.
Harvested a week early because of bud rot caused by calcium deficiency. I did a triple wash with hydrogen peroxide, baking soda and plain water to rinse.
Note for future
Coco needs a lot of calcium and magnesium.
With constant drip system you need way less nutrients in solution.
Check PH if you use calcium sulfate or silica!!!
Once cured the weed has a good nutty smell with a little berry. It’s not very
resinous, it has a good mind numbing effect but doesn’t lost more than one hour for 3/4 puffs, this is because of early harvest for sure because my previous crop was lot more potent.
