Going to be doing a thorough watering and feeding today. This is the schedule of the Blue Planet Elite 3 Part that I'll be using:
http://www.blueplanetnutrients.com/index.php?option=com_content&view=article&id=73&Itemid=113

Based on the age of my plants, 18 days, and the size, what quantities do you guys suggest?
I've done 2 feedings so far.

1st one used full strength under the Weeks 1-2 Veg schedule and I burned them quite good. Think day 8 was the first feed.

2nd feed was on day 15 when I discovered run-off PH was 8.5. I did 1/4 strength with PH'd water and watered aggressively and that was when the plants responded wonderfully.

Today is day 18. Think it's safe to use full strength on the Weeks 1-2 schedule?

If you are using quality coco with low EC and relatively soft water it shouldn't be a problem! Since they are 18 days your actually in week 3, and they should be able to handle 5 ml.

Google "research" and you find a picture of me! :) LOL Seriously borderline-OCD.. Actually longing a bit till the day i have my Perpetual-12/12-from-seed-mini-SOG set the way i like, with the right lights, seeds nutrition ETC. At least I'm getting closer. Might start a thread here when i start my next run, even if really don't have the time.. Hopefully the run after the next one i will be trying your winner strain out. The ones that looking the best in my garden right now is Master Kush and AK-48 from Nirvana. Grape x Bubblegum s the best smoke so far, but didn't yield well in my poor light conditions..

Will have 8 plants of the real grape fruit in my test run. Used to grow it under HPS, 7 years ago and was very pleased with quality, and pretty pleased with harvest..

Bro use only have strength as those feeding schedules are usually too hot for most strains. You should be able to feed with 1/2 without any burning. Remember growth was stunted when you fed at full strength early so you don't want to stress them too much. Start low and continue to work up week after week.

I hope you get the chance to journal too so we can learn from one another. Where I am ultimately going with this is the perpetual.

Okay, okay. I sense I am getting too impatient again. Thanks for reeling me in.
Why in the world don't these feeding instructions give proper amounts? It's like, if I follow the instructions to a tee I'm likely to kill my plants. That is just retarded.

That's because they aren't made for cannabis. And what most people fail to realize it's a marketing tactic to make you use more nutes so you have to buy more. If the nutes are any good you should never have to use full strength unless it's a heavy feeder.

Just be patient bro I know you want them to grow fast but the only way is giving it enough nutes and not pushing it past what they can handle.

It's nothing wrong with pushing your plants cus that's what you want to do to get the most out of them but you just don't want to be frying them up with nutes. If you see a lil tip burn it's ok cus that let's you know your at her limit just slightly over. The main thing is watch your plants after you feed. Go check on them a few hours after you feed and look at the leaves and the tips. See if there's any burn see how perky she is. This will tell you how's she's handling the food you've given her.

Half strength or quarter strength don't tell much if you don't know what "full" represents. And do you have soft water or hard water? Age of seedlings can be very misleading to.. The size of them matters more.. My seedlings were fed with an EC of 1,0 (that's more than half of the strength used in bloom) when they were in that age. I will feed them heavier in the next round, since the took it very well, and it apparently can help with stretch. But I grow under LEDs, and you under HPS so you have a lot more heat radiation going. Low humidity should also make plants more sensitive to higher EC's so there are many factors to take in to account. As AK-James tells you, you have to monitor the plants and see how they react to changes. New leafs should be lighter green than old ones. Very dark-green leafs and burnt tips is signs of nute burn. I've earlier feared over feading, but will aim at going as dark green as I can, without the burnt tips, in my next round, and then flush them generously. Hopefully this will help stretch. The article I posted is the reason for this. And watching Dels plants make me think that he also went/goes? Very heavy on the feeding.. But follow Akjames advice on how to up the EC. One should never do anything to drastic!

So I have to get something that measures EC. My piece of poop PH Pen broke after one use so I'm stuck with the paper strips and the small test kit that came with my GH PH Up/PH Down.

I went middle of the road based on both of your suggestions and mixed up approx 2/3rds the suggested strength for Weeks 1-2 according to the schedule. Did the Grow, Micro, Bloom and this was the 1st time I also did the Liquid seaweed and VitaBlue. My tap (well) water is a pretty solid 7.0 - 7.3 PH with 170PPM. After mixing these nutes I took another PH reading and it showed no noticeable difference...still right at or slightly above 7.0. I added just under 1ml of PH Down per gallon. I tested 5 minutes after adding it and then 35 minutes after adding it. After 5 minutes of adding the PH Down, PH read about 5.0 or slightly BELOW. After 35 minutes it read right about 6.0. The instructions clearly state to wait 15 to 30 minutes to test it. I simply don't have the tools to get as granular as 1/10ths of a PH point.

I went ahead and watered the most I've ever watered...About 6 oz per 3" pot and between 9 and 12 oz per 4" plant. Got great run-off. Tested the runoff and it was at 7.0 which is a big improvement from the 8.5 that the last watering tested at.

So this PH stuff is brand new to me. If my run-off is 7 and I'm trying to keep my water at 5.8 to 6.0, do I want to be trying to PH my water at like 5.0 and once my run-off is at 6 then I know Im good and then at that point try and PH my water going in to 6? Or should I expect that my run-off will always be higher than the water going in?

Just like Five said pushing your plants is what you wanna do but you just don't wanna push them to the point of stressing and burning and lockout.

I don't know what Five said is true or not about RH allowing for higher EC but I do know that strain and genetics plays a major role in how much the plant will eat.

The pH runoff is still high because I think you have a build up from when you fed full strength and not watering and getting runoff. Flush with pH water till your runoff comes out in the range it needs to be between 5.5-6.5 when flushing flush with 3x the size of the pot. Also coco has tendencies to get salt build up so when you water you want at least 20% run off to help rinse build up.

Main thing is to watch your plants after feeding. This will be your indicator to tell you if you need to bump up food or back off.

OK. Thanks, that helps!

I just looked up the specs on my pots and the 3"x10" have a volume of 1 Liter and the 4"x12" pots have a volume of 2.3 Liters.
Are you saying when I flush that I should flush with 3 Liters for the 3" pots??? That sounds like a crazy large amount of water.

Edit: sorry for all the newb questions. Im going to get reading on these topics.

150 ppm is pretty soft. That's good! You don't have to flush now since your plants are doing good. A bit of run-of 15-20 % should be sufficient to avoid salt buildups. Many people do well with no run-of. You don't have to care to much about the ph of the run-of water, that can swing a bit depending on what nutes your plants are taking up. If The EC/PPM of run of is much higher than the water you give them it's a good sign of that they bit are so hungry any more.. What substrate are you using? If it's buffered it should help with PH stability, but could also ad some EC. According to Canna you should not flush buffered coco with plain water, cause that will wash away the buffering agent...

I'm glad everything is looking good now!

The coco im using is this:

I have a lot of coarse perlite in there too tho...about 60% coco 40% perlite

Not crazy at all bro. That's how I flush my big girl in all perlite. Three times should wash away any build up but there's no need now as plants are growing good. Just keep feeding in the range of pH and get that 15-20 runoff like Five said you should be fine. Only if you see any major deficiencies should you flush like that
