Come harvest, I don't want my buds full of Nitrogren, maybe you do?
you remove most the fan leaves in late veg/ early flower, I reduce the food in late flower(5th week) so the plants get rid of the unneeded fan leaves.
The results more or less the same, no body wants a full canopy of leaves a week before harvest, could cause high humidity in the canopy and this could cause bud rot, also this will reduce the light getting to the lower bud sites and ripening them, resulting in airy buds.
No,no,no you’re talking about defoliation now. I was wondering why your plants are dropping so many leaves?


last 7-10 days in flower is the ripening stage, the plants starts to shed lots of fan leaves and the plants coming to the end of its life.

First page on the link that @.Smoke posted. This guys theory, he was saying his ppms (980-1000) were running high with the GH line and his bud came out tasting bad, from his experience the JR's was able to run a little less in EC/PPM without showing deficiencies. For example with my House & Garden Aqua A+B Flakes 45ml plus multi zen and root excel, and beneficial bacteria Miicrobial mass, I'm seeing 1100-1300ppm. 2.1-2.5 EC's and my plants are happy. I'd love to run as little nutes as possible like he was saying, at like 600-800. Just enough to keep them thriving.
600ppm max feed. High ppm/EC feed doesn't equal better plants.

I Lollipop my plant in late veg and again in early flower, haven't removed any leaves for a few weeks but I may start to open the canopy up by doing some light defoliation, give the cola's more room to grow.
IMO the plants need a large amount of fan leaves but they don't need a thick canopy.

I agree with you on this. 20211123_173500.jpg20211123_173436.jpg
Top view after Lollipop. Still nice and bushy.20211123_173727.jpg

all fertilize comes from the exact same 20 or less compounds. 75% of all fertilizer comes from about 7 basic compounds. they are essentially all the same. I have always made my own fertilizer solution
they are very inexpensive. it cost about 1$ a liter or less to make 100:1 concentrate

I run Jacks @ 3g, Calnit @ 2.5g and 1g of Epsom salt in veg only as I run LED's. I don't run any Epsom in flower under DE lights and at week 2.5 I add 0.5g of MKP. I run this from rooted clone to last 10-14 days before harvest. Last 2 weeks I'm lower co2, temps, EC, RH... pretty much drop all parameters in my room. I also will lower my Calnit sometimes in flower if the particular strain seems to be getting to green or leafy.

I've ran a few different lines, all very comparable outcomes, nute brand didn't make any real difference IMO.

3 different strains in these photos at day 42. Fed the above schedule with added drip clean, and foliar spraying Power Si and Remo's Velokelp in early flower only.

Bottled nutrients are typically the same stuff in Jacks just mixed with water so they're in liquid form and they cost more. In the end most of the ingredients in Jacks or bottled nutrients all come from the same fertilizer factories owned by Yara, Haifa, and other large companies. It's not as if these different brands are manufacturing the monopotassium phosphate, calcium nitrate, magnesium nitrate, or whatever. They buy in bulk from the same suppliers.

Thats an impressive set up, whats your highest EC recording throughout the grow? What size pots as well?

When asking this question it eventually dawned on me that it was indeed a stupid question lol. Ultimately you're right, what makes House and Gardens' fertilizers different from any other leading competitor? Nothing really, other than the difference in ratios/additives. Which is hard for a grower starting out to understand. I bought my tent, nutrients, seeds, and equipment within a month, didn't give a second thought to the nutrients at first bc of the ease of charts/time schedules. Kind of takes away the fun in the science lol, for some they need it (and still tend to make mistakes). I'd like to master the craft the proper way. I've researched coco and like the idea of organic amendments, the attentiveness given to coco and hydro are a pain to maintain at times. I will definitely be looking into an automated feed system and going the extra length to maximize self-sufficiency. I recently left for 2 weeks due to a death in my family, just got back 2 days ago.. had my girlfriend take care of things while I was away & I came back to one of my gdp's clawing, which to me is fixable, they would of died otherwise so I'm thankful. An automated, less hands on system would be great imo.

The biggest and main reason I run Jack's is because its dirt cheap. Its cost me a few pennies per gallon to run my nute schedule and I feel like I'm running all real quality products. I love how PH stable Jack's is and how easy it is to play with the ratios.

With bottled nutrients you're paying a much higher price to ship water around in flashy bottles.

Jacks for the win. No need to pay more for fancy cannabis specific nutrients. If people looked at the ingredients on those dozen bottles they're using they would see that most are the same ingredients in Jacks. The only reason they split it up is to sell more product. But you can't convince those that don't understand basic plant nutrition and are caught up in marketing and those 30% higher yields if you use product X. Plus all those shiny bottles look cool when they show off their grow to their friends.

Haha true that man. Smart marketing, just not worth the price.

I believe you are right for the most part, Jacks is cheap, effective and easy to use, cannabis specific nutes have a broad spectrum of quality. I did a lot of research on the cleanest nutes out there, Jacks ranked pretty high but the new commercial line from Dutch Master had less heavy metal contamination. Jacks was still better than most nutes though and the lower price compared to DM is probably from sourcing cheaper minerals, less marketing and less markup. If you look at organic fertilizers they have the highest heavy metal content of all. Surprisingly Advanced Nutrients had very clean nutes as well, but they are the ultimate ripoff artists when it comes to splitting up bottles for profit. Check this link and see what contaminants are in your nutes.

I've posted that same link. It's a good resource.
