Seedlings thriving on ridiculously high ppm?

So just thought I I'd share this. Bought 20 la cheese and 20 blue cheese feminised. Started out feeding them 0.5 EC (250ppm).after 7 days I noticed 4 were runts so tossed them to side but they were still under the light. I got some plants in week 3 of flowering in a tent and am feed them with an EC of 1.5 (750 ppm) with added calmag as I'm growing in coco.I fed the runts with that for the last week just to c how they would react whilst I been feeding all the other seedlings at an EC of 0.7/0.8. The runts have now completely over took the rest and show no signs of nute burn. Wat the fuck!!!

Most overfeeding isn't due to the fact that you mixed too many nutrients in one watering batch. It's due to habitual overfeeding, which causes the medium to retain the old nutrients, and it builds up over time.

^^^ I agree with this^^^

And....
I need to say, it's all about tolerance. Let me ask you this OP, when you first started smoking, did you start off smoking 3.5 grams a day? Probably not. More than likely you started out with just a couple of hits and built up to your current use, whatever it is.

Same thing with my plants.
I grow soilless and have complete control of nutrient intake. I start off slow with my young ones and gradually build up till I see the slightest bit of tip burn, that's when I know they are "full" so to speak.
In other words a person could push ANY plant to the limit, if they did it a lil bit at a time. If a person learns to see what it needs AND what is too much, he could push it to "maximum capacity" without causing harm. That comes with experience.

I honestly respect the fact that you seriously fucked with the runts just to see what happens. I learned a lot by fucking with plants that didn't matter

I c what u guys r saying. I always start of low and build up slow but my plants don't grow that fast in the beggining. Feel kinda conflicted now. Like my plants to be healthy but seeing how fast the runts r growing with a high ppm makes me want to start pushing them more now. Just gonna carry on feedin the runts with a high ppm and c wat they do

I start seeds with EC0.6 generally.

How much of the EC value is calmag?

How much of the EC value is your source water?

Usually though I never have to run any higher than 1.6EC feeding once a day during full bloom.

I start on 0.6 to. My water source is 0.4 and my added calmag in the flowering nute is 0.2. I don't usually start using calmag until i flip to 12/12. Do u start using calmag with seedlings straight off?

I only use Ca and Mg when they're required.

I have the canna mono bottles.

So your 1.5EC is made up of
0.2 calmag
0.4 source water
And the base nutes.

So your base is only actually 0.9EC

By using calmag this early on you want to watch out for Mg def later on down the road.

Most branded cocos are buffered to about 1.5EC anyway with a calcium source. Generally calcium nitrate.

Too much calcium can cause Mg def symptoms later on.

If it ain't broke don't fix it but the above could explain why your seedlings are seemingly thriving.

If you really want to fuck around with them on a high EC then you need to add 1.5EC of base nutes on top of your other EC values. Which would push you up into something stupid like 2.1. I don't advocate doing this.

Personally if it were me I would drop calmag for now as if you are using canna coco nutes then they already have 5% Ca and 2% Mg in them to start with.

It could be worthwhile finding out from your water company what makes up the 0.4EC in your source water.

My starting EC is 0.2 and it contains nitrates, phosphates, Flouride, chlorine, calcium, magnesium and a few others.

Some folks that have hard water (EC0.4 and above) sometimes cut it 50/50 with rain water to bring down the EC but then you could run into other contaminate issues.

Not to bothered about using the the calmag too early on as I'm only using them on the runts which I was planing to throw out. I usually start low like u and build it up slowly. I stay bellow 1.2 in veg and below 1.6 in flowering unless my plants tell me other wise.

They will because you have got them used to high feed but you are shooting your self in the foot in the long run because they would do well on a lower dose i never go above 1.5 ec after week 2 of flowering 1.5 all the way through

Only experimenting with the runts dudes. Not planning on even puting them in flower but they actually look a lot better than the ones I'm keeping on a lower dose. They were well behind after 7 days and looked like weren't gonna do nethin until I fed the with the food I'm feeding my flowering plants and they now well ahead of the rest and there not even directly under the light
