RUN OFF PPM IS THIS OKAY?

[greenthumbjudex]

I'm growing this baby out here under 12/12 cfl lights, day 14 from sprout, so here is the question, I feed her 500ppm and the runoff is 100ppm is this a sign that she is taking the nutes?

you NEVER need to check run off, it only tells you what ran out the bottom, learn to read the plant, that will tell you everything you need to know.

oh okay cause i saw some post that runoff ppm matters. I'm a newbie,

you will hear all kinds of non sense. flushing,bloom nutes, bloom boosters,check run off and many more. Here is the best advise for a newbie.
don't love your plants to death
LESS is MORE
keep it simple stoner K.I.S.S

Wait.
It depends on your cultivation method.
With soil you can’t check runoff, but with coco it is super important as u get your information way before the plant starts showing anything.

thanks man, and last question, Is this an autoflower or photoperiod? this is some random bag seed i found and grew her,

 

[greenthumbjudex]

@giantcola i am growing in coco/perlite mix btw

 

[giantcola]

You check runoff if you grow in a well areated medium with readily available nutrients, synthetics and hydro, not when growing organics

ok, I never used coco.

I guess you won’t know until she gets 3-4 weeks old, remember to check the sex as soon as she shows pre flowers, usually stress and training make this process faster

so does this mean that low ppm runoff means my girl is taking up the nutes?

 

[Mr. Krinkle]

don't ever waste your time checking runoff

okay so it's day 14 now and how do I know if it's an auto? and I started lst yesterday

If thats the case, your runoff ppm should match your input ppm. Not sure how its dropping to 100

 

[DaFreak]

That makes no sense to me, how can you add 500ppm and get 100ppm out? Normally you are going to have some salts in the medium and your run-off will be a little higher then what's going in. Lets say you added 500 and a week later your plants have eaten 400 of that and you add 500 again. The run off coming out will be that 500 that goes through and brings with it a little bit of the 100 that's left over so it should be over 500. The only thing I can think of is that your air-pots are filtering the salts out and your testing your run-off will tell you absolutely nothing of value. Don't worry, you don't really need to test your run-off anyway. It can be valuable information but even without it you can just read your plants.

it means NOTHING

thats the case idk why is she not taking up the nutes? seems like she is healthy

 

[giantcola]

@giantcola i am growing in coco/perlite mix btw

Did you buffer the coco? When such values are showing, i’ll guess the medium is locking up the calcium, has to do with cation exchange sites, and so the mineral comes not available as the coco bonds to it.
if that’s the case, i’ll suggest to check how to buffer coco coir or give the plant a massive calcium feed

 

[teddy bonkers]

Hey, I'm no coco expert, but why dose a high calcium to a plant that looks fine?

 

[Mr. Krinkle]

Does that plant look healthy to you? it does to me - so ya know what? don't chase your tail checking run-off for no reason other than reading about it somewhere
