Some of this stuff seem awfully high in numbers to me. I am a newbie at indoor grows, Are these total numbers or are they the 6 inch squares plotted out? Just purchased Mars Hydro TS 1000. from advice else where on this site said, might not get huge buds size of my arm but would have respectable harvest. In Tent 4 x 4' x 80" reflective inside.Found this list on growace.com:
- Seedlings: 100-250 (nutrients aren't needed here, hence there's not a lot of particles needed)
- First Half of Vegging Cycle: 300-400 (this is usually after you transplant, which still doesn't require many nutrients)
- Second Half of Vegging: 450-700 (you'll start giving your plants more nutrients at this stage)
- First Half of Flowering: 750-950 (your plants will be eating more as they grow, so they'll be taking in more nutrients)
- Second Half of Flowering: 1000-1600 (this is when your plant's eating the most, especially if you give it additives)
- End of Flower, Entering Harvest: As close to 0 as possible (this is when you'll be flushing your plants, so you don't want there to be a lot of particles leftover)
Would love to hear feedback from others here on these guidelines.
I'm suspect I knee-capped my last grow by overfeeding them; my PPM was in the 1500s in early veg. This round I am going to be more conservative and intend to use this guide unless feedback convinces me otherwise.
You're definitely losing mass if your nutes are too low during 2nd 1/2 of flowering but that's the trade off and would need monitoring on a garden by garden and adjusting for genetics also but the plants will tell you if you're burning them or its way too low i feel it doesn't matter how high others can take their ppm's unless you have a very good environment dialed in with the genetics and co2 is another factor that allows things to get pushed farther. But no shame in keeping things low sometimes especially depending on the strain and environmental conditions it maybe entirely necessary
Peace

Only place Mars Hydro has that high reading is center of pattern. A very respected lighting company in door grows?
Is there a wiki here for lingo?PPM is nutrients.
These terms are used in most home cultivation of nearly any plant.Is there a wiki here for lingo?
Thanks, I have printed this for future referenceThese terms are used in most home cultivation of nearly any plant.
PPM = Parts Per Million, an indication of nutrient potency in water.
EC = Electrical Conductivity. This reading is used to calculate PPM, but sometimes people refer to it directly.
PH = Potential of Hydrogen. This indicates the acidity or base of the media.
Humidity (assumed to be Absolute Humidity unless otherwise specified)
RH = Relative Humidity. This measurement accounts for air temperature somehow.
Lux (Not an abbreviation) = Light Intensity
PAR = Photosynthetically Active Radiation. A more affluent measurement of light intensity specific to growing. Requires more $$ gear.
VPD = Vapor Pressure Differential. Google this once you have a good handle on everything else.
That's all I can think of for now.
I'm with the newbie, I would never feed that high, I almost never feed more than 850, once in awhile to 1000 if it looks like it really needs it; The other numbers seem workable, so all-in-all a pretty good chart Nate, thanks!Some of this stuff seem awfully high in numbers to me.

Looks high to me too, especially the second half of flower rates. Thats when i usually start tapering the feed back if anything. About the highest i ever feed is around 1.3-1.5ec or 7-800ppm for the first few weeks of flower. Second half of flower is closer to 500ppm working down to 250 by week 7-9 depending on strain.
Plants outdoors below the 45th parallel grown under full sun are a different animal and can take far more though. Indoors, i almost never go over 800ppm unless the strain is a freak that wants more. But thats uber rare over here.
