Hi rickzski,

Our nutrient calculator is designed to simplify the calculations for commercial growers who don't grow autoflowers (that doesn't mean it can't be used with autoflowers). "Res" does equal reservoir and refers to the size of container you're using to mix your nutrients. In other words, it's the size of nutrient batches you make. If you do your nutrient mixing in a 5 gallon bucket, then your res size is 5 gallons. Then you just need to know how many times per week you make this batch. Typically it's 1-2 times with a water at the end of the week (over 7 days you would feed-feed-water).

Based on what you're using to grow, in veg, you will likely only need 5 gallons of feed formula for 3 plants, per week (maybe 10 gallons if closer to the end of the veg period). If this is the case, the simplest thing to do would be to set the res size to 5 gallons, with 1 feed per week,input the veg/flowering specs of your genetics, then print or pdf the veg chart. Then when your plants kick into flower, you'll probably need to make 2x 5 gallon batches per week. Adjust the number of feeds per week to 2 (with a 5 gallon reservoir) and print or pdf the flowering chart.

Now you have a customized feed chart for your specific grow.

I have to apologize, autoflowers have a component to them where they kinda do what they want when they want to, with regards to veg time. The print function helps a little bit with factoring in this.

Hope that helps,

Joel

Hey Joel,

Thanks for the lightning fast reply! And thanks for the additional information. This was exactly what I needed. I can't wait to get started! WooHoo!
 
Hey Joel I start feeding day ten to twelve.I use 15 liter jugs I use pro mix HP with added perlite. I feed drain to waste. I feed lightly until day 20 I usually start feeding day ten with one quarter strength a/b grow and one quarter strength of the root enhancer until day 20. Then I add my cal mag supplement at half strength to the mix until day 30 to 35 between that time I then switch over to bloom nutrients between a quarter to a half strength. Buy day forty I will be at half strength of bloom nutes and half strength of supplements. I up the bud booster as they get on in life I usually grow some nice size plants. Autos can be fert sensitive IMO. I only feed water every ten days starting around day forty usually no more then two to three litres just a drink. I flush for ten days to. Thank you for any advice moving forward using your fine product.

Hi Fairlynew,

Aside from flushing at the end of your cycle, there is really no right or wrong way to grow your plant if things look healthy.

In my honest opinion, your feed schedule shouldn't have to be that complicated. Because of the number of grow products that have come into our office over the years, we've had the opportunity to try pretty much every method of growing and the biggest piece of advice we have is to reduce the amount of steps you have to take (across the board) to get to the end of your grow. It's kind of like how new dishwashers always seem to break down in ridiculous ways because of complex electronics, and that ugly old dishwasher does the same job but if something does happen, it's cheap and easy to fix.

Cannabis is an extremely sensitive plant, especially autoflowers, and you can see this if you just brush up against the secondary stalks of a bigger plant (they'll lose rigidity and start to droop...assuming it's not staked).

Our recommendation would be to keep the feed concentration the same, relative to the size of the plant. Start with a lower concentration (5ml/G) when the plant is small and increase the dosage weekly by 1ml/G until you hit (10ml/G). In our experience 1250 to 1350 ppm is the maximum your plant needs, and any more will just increase the risk of excessive salt buildup or lockout. Once you hit the 10ml/G level, there's no need to increase the concentration, only increase the frequency of your feed, which is to be expected when a plant gets bigger.

You already mentioned flushing but for those who don't know....FLUSHFLUSHFLUSHFLUSHFLUSH...for AT LEAST one week and up to two weeks. If you're using anything (organic or synthetic) with nitrogen or magnesium in it, you need to give the plant time to metabolize them or you risk a final product that tastes like chemicals (nitrogen) or sparks and pops when you smoke it (magnesium). Other than that:

- always cut off fan leaves that are yellow and dying (they never come back)
- always keep plant matter off your soil bed
- gauge your plant's need for water/food by the weight of the pot, not what it looks like on the top of the soil.
- make sure you're enjoying the grow experience; I don't believe in the whole "positive energy" thing, more that people tend to make errors and spontaneous decisions they regret when they're stressed out.

Hope that helps guys and gals,

Joel

Welcome to AFN urbanremo, I've enjoyed your YouTube videos for some time. Autoflower breeders have advanced the genetics of this form of cannabis tremendously over the past few years, equaling and often exceeding the quality of many photos. Most people seem to hold autoflowers in low esteem, which is their loss. Given the short lifespan of autoflowers combined with often excellent genetics and improving yields, I consider the market for autoflowers as being extremely bright as more and more newbies join in the growing fun.

Again, welcome to the premier autoflower site in existence and best wishes as you explore the fast growing (pun intended) world of autoflowering cannabis! :thumbsup:
 
Hi again Joel,

2 questions about your nutrients:

1. I have a reverse osmosis water system which makes my PPM very low. While I am using the Remo program, will I need to add any trace elements back to the water like calcium and magnesium (or anything else), or will my plants get everything they need solely from my near-zerp PPM water and the Remo nutes?

2. I am using a feminized autoflower starting from seed. The seed folks report that total time to harvest is 90 days. A helpful lady at your office told me on the phone that since I am using soil that starts out pretty nutrient rich already (Fox Farms Ocean Forrest), that I should consider giving the plant no Remo nutes for the first 4 weeks in order to avoid burning the plants. However, if I wait 4 weeks before starting the 12 week Remo nute program (4 weeks for veg / 8 weeks for flower), I will either be waiting too long to harvest, or I will be giving the plants the veg schedule well into the first 1/2 of the flowering phase. Can you elaborate on what I should do please?

Any advise you can give me about the above two issues would be greatly appreciated.
