Growing it




The smell was initially largely herbal before it was dried. Eucalyptus comes to mind. Once dried, it really does smell like when you peel a mango, with the herbal/eucalyptus-y smell following very closely behind.

I can't say much about taste. I've never been one of those people who can tell different smell 'notes' while smoking, so I'm not gonna start making shit up. It smoked and tasted like weed. Solid, dense draw, but smooth as far as I'm concerned.

I really enjoy the high. I spontaneously wrote an entire essay while high; the ideas just came flooding. Mustn't lay down on a couch though, because if I do, I can't get up. I say that it might have a paranoia effect, just because I don't trust myself to behave normally around people when high, as I became seriously chatty, and focus/obsess over minute details. I'm pretty sure that's suspicious behavior.

During the last 2-3 weeks of flowering, it became apparent that it had phosphorus deficiency, as pointed out by the kind masters here in growdiaries. I upped the P using MKP (a typical bloom booster), but I don't know if it did anything. Maybe it stopped the progression, I don't know.

Also during the last half of the flowering, the pH swing was crazy. I'd pH the rez high to 6.5, and it would have dropped to 5.6 by the 2nd day. This plant was eating a lot. I need to figure out a better flowering nute for my next grows.

It's very useful. Pretty much solved my calcium deficiency.

Well this is my first diary in this site, and I must say, it truly is useful to document everything. Thank you very much for the kind masters on this site who have helped me along the way. I water cured a portion of my harvest (~1/5) as I have always had nothing but good experience with water curing. Started with 901 EC @ the end of the first day, and finished on the 5th day @ 37 EC, then hang to dry for just 2-3 days.

Unfortunately I didn't bother to measure the wet weight; I just don't think this tells me anything useful. Final yield after drying and storing everything is as follows:
- Tops: 104 g
- mids: 54 g
- larfs: 29 g
- Water cured: 40 g (most of the mids and some tops went here)
- Sugar leaf trimmings: 33 g
Total with trimmings is 260 g, but I think we should leave that out. Grand total is 227 g.

I'm very happy with the numbers of course. I'm also very happy about how frosty the green crack is. I am very sure I got lucky with the genetics I got. I am still looking for that elusive great tasting weed though.

There are quite a few things I have learnt from this grow for my next:
1. I went the long-veg way, and I don't think it was the best idea. Fun, but not the best idea. Because the tent was so full, I couldn't trim/defoliating the stems towards the back and so had a lot of mids and larfs. Those were HELL to trim.
2. I need to try better flowering nutrients. The current generic nute I use for veg is perfectly fine. But the flowering nutrient doesn't have enough buffering, I think. The pH swings are too dramatic (~6.5 to 5.6 pH in 2 days? Come on.).
3. I should have started the flowering a week earlier, that way I don't run out of headspace. Unfortunately during this grow I was away on a trip.
4. One layer of SCROG net is not enough. I must add a second layer above to support the heavy flowers. In this grow they toppled because they got too heavy and the stems weren't robust enough to hold them up.

I'm gonna take a break from growing for a month or so. I need to do some cleaning and process the harvest to oil/rosin/etc. But once that's done, next stop: DNA Genetic's Blood Orange Sorbet. Stay tuned!

Grow Questions
JKT48 week 3 started grow question 1 year ago
I've been having this problem with the browning leaves on the bottom.
1. Every time i do DWC from seed, the picture as shown on Week#2 Day#11 happens. Why is that?
2. What do you think is causing the browned lower leaves? Is it calcium deficiency? Or potassium?

That doesn't really look like a calmag problem to me but it doesn't hurt to add calmag if you haven't been. It honestly looks kinda like nute burn.. 1.8 EC is a bit high for plants this age. I've been feeding around 1.3ec and my plants have been loving it. Granted I just grow in coco, not dwc, so that may be something that is a bit different between the two. I also see your ph is at a 6 which is okay but I've personally seen better results in my coco keeping the ph around 5.6-5.8. Either way despite the crappy looking bottom leaf the rest of the plant looks perfect! So it may just be an odd thing that happens and it may not really affect the grow as that'sIve a lower leaf that you would prune anyways.

I’m referring to the last 3 pictures in week 7. Those leaves are near the bottom of the plant, not getting enough light. I thought they’d yellow gracefully before finally crisping up and fall off. But these are dying gruesomely. Is this normal, or a nute issue? What’re those?
Leaves. Other
LaBossanova answered grow question 1 year ago
Hey Secondo , the damage is from the plant canabalising itself because it's missing calcium (that's the spots on the leaves) and magnesium (that's the dying parts on the side of the leaves and the yellowing between the veins) . In hydro you do need enrich the solution with cal mag so the plant gets the micro nutrients it needs - so add some micro and the problem will stop spreading and the plant will recover in 10 to 14 days. Hope this helps ! :rocket:
JKT48 week 13 started grow question 1 year ago
I am currently defoliating my plant gradually. But I worry that I am not doing enough/too much. Could the grand masters here help me by taking a look at my latest entry (Week 13) and see if I'm doing this right? Do I need to further defoliate? Or is this enough?

SpinnerCaribbean answered grow question 1 year ago
The top and the bottom are perfectly defoliate. Now concerning the middle it is hard to tell , the pictures doesn't really shows if some leaves are blocking light , however I can spot some leaves that can be remove. Just try to have a maximum light exposure to every bud sites , you can still pluck a leaf or 2 but carefully , just for optimisation.

Dear ganja gurus, please have a look at my diary Wk17 D119. I'm thinking nute lockout due to pH always below 5.8. But any other inputs is most welcome. Nute is 50 ppm epsom, 100ppm CaNO3, 100 ppm MKP, and topped with 7-5-16 A/B to 900ppm.

First and easiest way would be to push the PH up to 6.1 - 6.4. If it doesn´t get worse you did it right.
JKT48 week 20 started grow question 1 year ago
Dear masters; do you think I harvested much too early, based on the pictures? If yes, how many more weeks would you say I needed?

I dont think you harvested too early, but another week would have been good too. Plants and buds looking great. Your harvest depends on the high you like. I try to harvest by 10% amber trichomes and the rest mostly milky. When trichomes start to turn amber they actually turn from THC to CBN which will provide a more narcotic, couchlock high. Milky trichomes have the highest THC and clear will have a more racey high.
