I have the nitrogen (N) hydro nute bottle the phosphorus (P) and potassium (K).

I am trying to match these to your charts,
Any suggestions.

I also plan to invest in more addititves..

I guess I am just looking for a basic chart or atleast a direction to head in.

I have yet to find a feeding chart for my nutes (Natures Nectar)

They have mixing charts on the back of each.

I need to know when to use more of each one or which one.
I know N is for growth.
I think P is for rooting and blooming
I am not sure what K does.

Once I get the basics then I plan to start introducing other additives.

Is yours an Organic Nutrient, Mid? These are GH's Feeding Schedules. Your nutrient maker should have a schedule for feeding on their website.

What brand are you using?

But actually...You can get a general idea of how much to feed and at what time by GH's schedule.

About week 4 I'd make a transition in the nutes. The levels of each should be close to even @ week 4. Week 5 your N should be lower than P &K. Thats a start.

Nitrogen - Plants need lots of N during vegging, but it's easy to overdo it. Added too much? Flush the soil with plain water. Soluble nitrogen (especially nitrate) is the form that's the most quickly available to the roots, while insoluble N (like urea) first needs to be broken down by microbes in the soil before the roots can absorb it. Avoid excessive ammonium nitrogen, which can interfere with other nutrients. Too much N delays flowering. Plants should be allowed to become N-deficient late in flowering for best flavor.

Magnesium - Mg-deficiency is pretty common since marijuana uses lots of it and many fertilizers don't have enough of it. Mg-deficiency is easily fixed with ¼ teaspoon/gallon of Epsom salts (first powdered and dissolved in some hot water) or foliar feed at ½ teaspoon/quart. When mixing up soil, use 2 teaspoon dolomite lime per gallon of soil for Mg. Mg can get locked-up by too much Ca, Cl or ammonium nitrogen. Don't overdo Mg or you'll lock up other nutrients.

Potassium - Too much sodium (Na) displaces K, causing a K deficiency. Sources of high salinity are: baking soda (sodium bicarbonate "pH-up"), too much manure, and the use of water-softening filters (which should not be used). If the problem is Na, flush the soil. K can get locked up from too much Ca or ammonium nitrogen, and possibly cold weather.

Phosphorous - Some deficiency during flowering is normal, but too much shouldn't be tolerated. Red petioles and stems are a normal, genetic characteristic for many varieties, plus it can also be a co-symptom of N, K, and Mg-deficiencies, so red stems are not a foolproof sign of P-deficiency. Too much P can lead to iron deficiency.

Iron - Fe is unavailable to plants when the pH of the water or soil is too high. If deficient, lower the pH to about 6.5 (for rockwool, about 5.7), and check that you're not adding too much P, which can lock up Fe. Use iron that's chelated for maximum availability. Read your fertilizer's ingredients - chelated iron might read something like "iron EDTA". To much Fe without adding enough P can cause a P-deficiency.

Manganese - Mn gets locked out when the pH is too high, and when there's too much iron. Use chelated Mn.

Zinc - Also gets locked out due to high pH. Zn, Fe, and Mn deficiencies often occur together, and are usually from a high pH. Don't overdo the micro-nutrients-lower the pH if that's the problem so the nutrients become available. Foliar feed if the plant looks real bad. Use chelated zinc.

Hey Midgrade how many weeks into flowering are the plants in your picture? I have some mid 7 wks into flowering. They are all in a perilite and vermiculite mix. Im starting to see yellowing of some of the leaves but the buds look very healthy and are starting to turn amber especially the main cola @the top .Do you know what could be causing the yellowing will upload pics soon.

At 7 weeks into flowering, you should almost be done growing it.

Assuming an 8 week flower cycle, I wouldnt be concerned about it, that is normal.
Peace

Week #1 -----------18 ---------------5ml ------2.5ml --------2.5ml------------400-800ppm

Tell me if I'm misunderstanding this. Lets use week one as an example. So for every 1 US gallon I should add 2.5ml bloom, 5ml grow, and 2.5ml micro. Now if Im using 6 gallons would I adjust accordingly to how high of a percentage strength I want for nutrients (i.e. 6 gallons = 15ml of bloom at 2.5ml per US gallon = 100% strength). Where as if I wanted 1/3 strength it would be for 2 gallons = 5ml of bloom at 2.5ml per US gallon. Sorry for any confusion, just new to the whole grow process and my biggest hurdle now is getting the nutrients right.

same here dude...hardest part for me is getting the nutes right..i have just been going half strength of what the bottle says the whole time and using my ppm meter to make sure i stay at a medium range. right now my girls are 12 inches avg. and i just started flowering them (going for SOG method) and my ppm's are sitting at 700-800 with just a mix of bloom, a micro supplement, and some calmag.

im wondering how high i should have it if im wrong and how high i should allow it to get as the 9 week flower cycle continues.

they are really lookin nice though so im hopin im on the right track...my biggest concern is not overfeeding, but underfeeding and not getting the full potential of my ladies.

im new at this ppm ph stuff also. just went from dirt to aerojet. my ppm is 734 last time i checked(last night). my girls are growing after 3 days in the system. better to use less than more. play with it for a few crops to see just what your plants do. im using gh cause im in an aerojet and want to minimize jet clog. been told tomatoes are a very close cousin of cannabis. they like similar conditions. just watch your plants. if they are growing slow bump it up. be careful. your right about the one third strength, keep your gallons the same reduce you nutrient. if your plants are in veg and growing good i would start out at half strength. like i said tho i am new to this also and i could be wrong. its what i would do.

Hey Madmax420,I'am going to call you mad or max for now,You are under standing ppm's.The water you start with has a ppm number lets say 245 ppms is the water.The first week the ppm for GH 3-part nutr is 200 to 400 ppms.This is clones and seedly.You can use the weekly feeding charts at hydroponics.net at the top of the page click on infor and you will see all the charts.You have 6gal res for week one ppm's should be 400 to 800, 15ml grow 15ml mirco 15ml bloom.You know the water is 245 ppms and you mixed the nutr and your ppms is 743ppm you are fine.Now if the ppm's were high like 1000 and higher take 2 gals of the mix from the 6 gals and replace it with plain PH water{distilled if you have it}This will lower the ppm'sBesure to always mix the mirco in the water first and stir it well.Then add the grow and bloom.Adding anything to the water before the mirco can lock out some needed nutr.As the grow go's along the ppm's will rise and fall.when they rise top off the res with ph water and when the ppm drops down low it time to change the res.I set my res up at PH 5.6 and this time it's week 9, 20gals water I mix the nutr by the chart for 18 gals.My ppm's are 1450ppm and the chart says 1000 to 1400 ppm's.This is how I keep the ppms in side of the range on the charts.A couple times growing hydro and you will see how much nutr they will hanndle and not burn.You guys are doing great keep it up. Peace
