Foxfarm isn’t answering their phone today – I’ll try again on Monday.
I’m not saying you’re wrong. The chart is ambiguous, though, and I’ve wondered about this question before.

Greetings,
True ,true, I have been doing research on this since your reply. Now where on line have I found a good answer all leave you hang on this chart, not to mention the levels of E.C. per plant stage.
At a vendor show a fox farm rep explained it to me the way I have been doing. E.C. is nutrients that is in the pot it needs. Add the nutrients to carry thru to next weeks feedings. We all look for the level of each stage it needs and that is in the pot so follow by whats in the pot it is eating is that level.
It’s interesting to find out maybe, just maybe a good level for each stage as well.
I was told to many strains for each photoperiod and autoflowers need different levels there are no good one answer. Even General hydroponics rep gave that to me on the way out the door for Christmas on the phone as he was leaving this statement.

Greetings, brother.
I you come up with something let me know.
But I a a foxfarm man thru and thru and have been knocking it out of the park for years. I use everything on the chart the dirty dozen, with adding Genaroot and Stump vea tea and cal/ mag.

Let me understand cause maybe I got it wrong. Gotta hit me with a brick sometimes to wake me up. When you say “running thru ph water”, you’re meaning ph’d nute water mixed to the PPM on the chart for the stage of the plant and “run thru” the pot until the runoff PPMs are the same? Is that the "15 to 20% runoff you’re talking about each watering?
Hey sorry @Bryce for sorta hi-jacking your thread here. Just trying to get it staightened out for when I go back to FF nutes.

Greetings,
I was told that the industry uses E.C. as a standard in European and American cannabis growing. Information shows on growers across the country for dispensaries use as well. I don’t care but reps seem to use E.C. when I speak with them as well. I have both Aprea pens. Who cares. Just throwing out useless info of the day.

Yeah, I think I commented on a some pics of some of your ladies in another post. Put my girls to shame, made me cry. 
I’ll have to try some of that stump tea!
That’s a good practice because ppm is ambiguous if the conversion from EC isn’t stated or clear from the context. The FF chart states that its ppm numbers are based on the x700 conversion, though, so no problem there.
Ive had a hard time with the ff trio. Can never seem to get my runn off to go below 1700 lol but my plants seem to love it

Greetings, yes Bryce sorry brother.
Load your bucket say 5 gallon with any amended soil put ph water that the cannabis likes say 6.5 set to. Pour it in check your run thru say its a E.C. of 2.50, well we both know its to hot to put a seedling in it and then start feeding nutrients to it. You can put a seedling in it but nothing but water until the plant uses it or the watering lowers it.
So you generally have to wait using these soils for 3 to 4 weeks before giving them a full feeding. So if you take that same 5 gallon pot of soil pour in ph water to 6.5 as many times as it takes to lower that run thur to the level the chart says for the E.C. for that 1st week of 1.00 E.C. then you feed per the chart the full dose of nutrients it needs to carry you thru to the next feeding. I you need more explanation hit me to get off of Bryce.

Greetings,
The soil has the nutrients in it for taking care of them up to 3 to 4 weeks. Why waste nutrients until then and burn up you girls I either use old used soil and set the E.C. and ph by watering with nutrients until the 1st weeks recommend E.C. to start the full nutrients feed per chart. Or start out using new soil and waiting.

You are all good man please go ahead and explain! Just here checking in and everything. I’ve seen my plants today and idk man I’m seeing more and more spots….

I got ya, I’m following you now. My first two grows were using FF nutes. I didn’t have a clear understanding of the feeding chart then. It’s gonna be a few grows down the road before I go back to them, I’ll certainly hit you up for more info then. Thanks.
I agree with 
Keeps those spots away. I read along the way if you don’t give them cal/mag early on, you can’t make up for it in flower.

Greetings, please send close up photo under natural light.
Also kinda wondering why the color is becoming such a huge difference between the 3?
Here are the spots:

Greetings,
Flowering beats the crap out of your leaves, they are the food storage houses so it is understandable that they must suffer, unless you replace the nutrients it needs toget thru. If you are using 5 gallon pots a 5gallon pot needs 1 to 1/2 tsp of cal/ mag. Also your leaves shows you need a nitrogen boost I think I showed you the stump veg tea thru HTG .com use 1 tsp per gallon of water be sure to ph.
One big question how many feedings have you given your plants with nutrients.
Look at the chart you need to do a flush right after 4 weeks of seedling going into flower using sledgehammer. Let dry then continue to give nutrients for three weeks the flush again then three weeks flush again.

So is everything normal though? The spots? Also do you think I should sledgehammer flush them? How do you do a sledgehammer flush? I’ve only give them 1 feeding of nutes this entire grow. 5ml of big bloom and tiger bloom mixed in a gal and fed to them after I already watered 1.5 gal. Not sure if I’m going to water Sunday (which is normally when I water) because I watered them 2.5 gal of water between them. Maybe they will need it. Haven’t picked them up yet.
Greetings,
How big of pot do you use?

3 gallons
Greetings,
Flushing probably not needed since you have not been pushing nutrients. Cal/mag definitely needed, nitrogen needed. You get nitrogen in grow big and tiger bloom of 4 each but you have not been feeding them. My honest guidance is start feeding them using the Chart, they are starving try to feed at least 2 times a week. How old did you say they are?

Greetings,
Try some more nitrogen for a while as well, 1 tsp per gallon. This helps the yellowing to dimish in the new grow. The additional starting to feed will get them smiling at you.
Not to feel left out my first grow I was where you are at and Hellraiser took me under his wing, I ended up getting 1 pound of Granddaddy purple in 4 plants. I honestly thought my soil is all I needed until I got to flowering. I even broke the cola off of one. He talked me thru splinting it.
