Day 52:
Yet again slow on the updates due to work but I'm determined to finish out this journal for my own notes and also to hopefully help others.
So since my last update, where I had fed at 850PPM, I did start to notice the nitrogen clawing increasing and leaves getting a bit too green, so I wanted to pull back a bit on the Mega Crop but wanted to wait and see if everything straightened itself out. It didn't. Started seeing some leaf tip burn, so I pulled back again to 750 PPM for a little over a week, then upped it to 800PPM, the plants were ready for that dose by then and the leaf tip burning had stopped, same with the nitrogen clawing. This told me I was at the sweet spot for Mega Crop for this grow at that particular time.
However, around that time, I noticed a cal/mag issue starting to get a little worse. I thought maybe it's time to raise the Mega Crop does again, so I did, up to 850PPM again and got leaf tip burn and nitrogen clawing... again.
This told me that while I was at the right PPM dose for MC, either my LED light was burning the plant through it's cal/mag or this particular strain just needed a bit more supplemented.
So... I decided to pull back on the MC to 750 this time and introduce some cal/mag from a bottle I've had lying around. I started small and noticed the issue subsiding a bit but then it hit me...should I be mixing in the cal/mag before or after mixing in my base nutes (Mega Crop) I did a bit of searching...I'm good at searching, obsessive almost..scratch that....I am obsessive in my research...it's part of my actual job.
Apparently, and I can't remember the exact scientific reason, but it has something to do with molecular bonding or some shit, the cal/mag is SUPPOSED to be added before the base nutes otherwise the reaction of adding it after doesn't let the molecules attach or bond which causes the cal/mag to evaporate or something like that. It'll still have an effect, but not nearly as potent and you have to use your solution before all the cal/mag disappears or whatever.
Anyways, I wanted to get Greenleaf's take on it.
This is where it gets fun (sarcasm)
So I reached out to Greenleaf Nutrients on facebook. Asked if, with Mega Crop, it's best to mix cal/mag before or after mixing in Mega Crop. Here's how the conversation went:
ME: "Hey there! So I've been really enjoying using Mega Crop, I've never had a better grow, sincerely. But I had one quick question because I'm a total noob. If my plants need a little extra CalMag, should I mix in the CalMag before or after mixing in the Mega Crop?"
Greenleaf: "I would just raise the Mega Crop dosage"
ME: "raising the MC dosage gave a tiny bit of nitrogen toxicity and burnt tips, so I need to dial back on the MC and supplement with a bit of CalMag"
Greenleaf: "OK, do you have any pictures you sound send showing your problem?"
ME: "sent pictures"
ME: "So should I mix in the CalMag before or after mixing Mega Crop?"
Greenleaf: "hi, that does look like possible Calmag issue, or also possibly P. You could add extra Mega Crop (that would help with P also), or you could also add in some extra Calmag as well. Either or both should help"
ME: "Great thanks for the tips, much appreciated, but I was still hoping you could tell me if you recommend mixing in the CalMag before or after mixing in the Mega Crop to the water"
Greenleaf: "doesn't matter"
End of conversation.
Now, I am absolutely loving using Mega Crop. It's been fantastic and easy to dial in while providing explosive, trouble free growth...however
I'm a bit taken back by this level of customer service over such an extremely simple request. "Do I mix in the cal/mag before or after mixing in Mega Crop"
A simple before, after or even the SUPER helpful "doesn't matter" response would've sufficed. Instead, I had to repeat myself twice, explaining that raising the Mega Crop is burning leaf tips and causing nitrogen toxicity as well as repeat my question 3 times before getting a 2 word response.
And for the record, according to what seemed like scientists or biologists answering this question on multiple forums, it DOES matter and the definitive answer is, before the base nutes.
Maybe it doesn't matter as much as the science nerds said it does, but I like science and facts, and even if it only makes a tiny bit of difference, I like to go by the book...the book of science.
Now that said, this isn't the first time I've questioned their customer service abilities. Don't get me wrong, I'm grateful that they even replied same day, most companies wouldn't, but in the past, while iquireing about re-stocking here in Canada, it was one delay and excuse after the other.
Regardless, they always replied and always provided. At the end of the day, I still have a product I'm just over the moon happy with, but I mean, come on, anyone would've been frustrated with that type of a customer service experience, especially one that could've been so simple, lol.
AAAANYWAYS, after mixing in the cal/mag before the MC and 2 more feedings, the cal/mag issue completely stopped.
Since then, due to the health and stage of the plants, I have continued the MC does at 750PPM with 125PPM of cal/mag. I did get a bit of tip burn, but the plants quickly adjusted, I'm thinking due to timing of full on flowering stage, the plants were right around the corner of needing this much. I've also stopped adjusting the PH.
The reason I've done this is because cal/mag is BEST absorbed at around 6.3 to 6.5 PH and with my city water, after mixing in the MC, the solution is brought down to 6.3. So I figured I'd let it go for a bit and see what happens.
What's happened is no more tip burn, no more cal/mag issues, no more nitrogen toxicity. In fact I''m tempted to stop giving them extra cal/mag and just leave the PH at 6.3 but I'm afraid of experimenting this late in the game. I don't wan't to bolster growth and flower production. Everything is smooth sailing right now and I don't wanna rock the boat.
Anyways, looks like at this stage, mid-flower, for Candy Cane Auto, 850-875PPM is the max. At least for me in this grow.
Over the past couple weeks I've kept up with the low stress training by holding down branches, but at this point, the plants have taken their shape and not much maintenance has been needed.
I did end up doing what some might consider heavy defoliation. I didn't go nearly as hard as I've gone on past grows, but it needed to be done due to humidity concerns....and then I remembered I had another ventilation flap on the tent I could've opened and tried first but by that point it was too late. Either way, I opened the flap, the plants of been pruned and defoliated and the humidity has gone down to exactly where I want it - 50%
I'm feeding/watering every 2 days, when the pots get dry but not light as a feather dry. I've noticed there's dry, where the soil is the light brown colour and the pot is light weight, but then there's next level, light as a feather dry. I've only let them get there once, since then I check twice a day.
The LST was the key here though, both for creating more colas but also for height management. I'm going to have several large colas. The node structure is just tight enough that many of these colas should be as long as my forearm, hopefully they get as thick too!
The smell is sweet, very, very sweet. I don't know about "candy cane" but I sure can smell the candy! My god is it sweet smelling.
The plant on the right is still doing better than the one on the left but oddly enough, while the one on the right is already showing signs and promise of heavy resin production, the plant on the left is barely showing any resin production but on the other hand is already producing larger buds than the one on the right!
Weird genetics obviously, but either way, it'll be good.
Anyways, looks like I won't be testing the smoke before Christmas, which is what I was going for, but I guess I fucked up the timing. At least I'll get to start off the new year with some quality cannabis!
Anyways that's it for this update. It'll probably be another 2 weeks until I update again. I have a ton of video production planning work to do, which is beyond time consuming and at times..... nose bleed inducing frustrating. So I'll try my best to check in and reply to comments and or questions if there are any.
Thanks for stopping by!
Here's some nice update pics, enjoy!
This is the plant on the left with minimal resin production
The is the plant on the right with much higher resin production
