The plants are like 30-40 cm tall as i lst'd them abit
Temps stay between 23 and 27.5c° humidity between 40-60
Lights on 24-7
180 watt diy 3000k cob and 125w 6400k cfl
how much liquid are you dumping in there per feeding?
have you grown successfully using the exact setup that your using now before trying coco, the coco is the only change?

whats your ec and ph going in and whats the ec and ph in the run off? when in doubt give it a good flush @ 5.8 then wait 24 hrs, feed only once per day and watch your new growth.

No i started with compost chicken shit kelp and other amendments.. switched to coco as saw a friends explosive growth.. so 1st time using coco and 1st time with floranova bloom
And i was watering till i had sufficient run off.. then read not to so fed till a few drips then yesterday flushed with low nutes and they seemed to perk up abit

Floranova bloom is 4-8-7 and supposedly at 8ml gal is the lucas formula
Although i am using tap
Would it be better to use rain water instead for lower ppm

I ph to between 5.8-6.2 i dont have ec or ppm meter but i have never went over 1/4 strength
if you dont have a way of measuring your ec then why are you feeding it twice a day? you prob have a build up of unused nutes in your coco, flush it and wait 24hrs then only feed once a day.
ps get an ec pen. whats the ph in ur runoff?

Mrherbal,
I'm not sure why bottletoke is pushing you to flush. At those low feedings and an occasional watering to runoff...you should be OK. And you know to never give just water? Bad idea in coco. I know you are paranoid about overfeeding...but if you increase the strength slowly...you'll be ok. You can safely bump up nutes from where you're at.

Just a comment about your old abandoned plants that you are allowing to die. Weak plants are easily infested with bugs or even disease...that could spread to your healthy plants. So either cut them and clean up the area or care for them. You might learn something trying to help them.

just looked at your other pics and yes she is in flower;-)
first dont panic, shes not that bad. growing coco will pay off after you get over the learning curve. coco is hydroponic so there is no buffer and no other nutrients beside what your giving her. once figure out how to read the plant the battle is over. main issues have to do with the ph of the rootzone, overfeeding will effect the ph so compare whats going in with whats coming out. when u get it all dialed in youll be happy you changed, unless bigger, better and faster yields are something you dont want....

tap is fine if its drinkable
Tap water is fine if it's 250ppm or under. If you have super hard water...your ice cubes will look very cloudy.

Minerals add to the taste and so drink-ability or taste is a poor way to judge water suitability for plants.

I am feeding twice a day because the pot is dry by then and was under the empression that i had to feed every watering
This is why im feeding low nutes everytime i water with some runnoff to get rid of old salts
I thought multiple feeds would draw in oxygen constantly replacing nutes as coco is hydro

Is that wrong?

I also thought that yellowing tips where nute burn.. some people so over feeding some people say underfeeding

They are autos so probly dont need as much but would of thought they would handle more then this

My water is supposedly moderately hard.. wether thats trustable is anyones guess that was my reason for suggesting rainwater as that would have less ppm allowing me to bump up feeding maybe

u beleive that negative ionic pressure hype or it causes stress? i flush with 0ppm once every 10 days in flower and every 3 days in veg, never had an issue.

Ps, whos that in ur avatar?

But what about the tip burn?? Or is that not a problem?

The abandoned plants are still getting watered and fed but i just gave up trying to help them.. at first i was feeding them ph 6 as it was basically soilless but because of the dolo lime i thing they were being buffered to much... then i just started feeding water and nutes without checking ph to see if that changed anything but they still look shit so just carried on not ph'ing

How would you suppose i treat them??

I didn't see any tip burn. Yellowing is not nute burn. If you bump up your nutrients slowly...you will see a darkening of the green way before tip burn. And if you do get tip burn (necrosis) just back off and carry on.

Experienced growers who are pushing plants with high nutes and CO2 will often keep increasing till they get a tiny bit of tip burn. That tells them what the upper limit is for that strain. Not saying you should do that. ..but it isn't a death knell for the plant

Hi bottletoke...we make a great effort to presoak coco with the proper cations (ca and mg) but flushing with zero ppm water will undo all that. That being said...I've seen experienced growers flush with just tap water if it has some minerals in it. But def not RO water.

The Avatar I picked up on a free avatar site...no idea where it's from. A buddy told me he's seen something similar in a vid game. I like the sinister look. I'm actually a grey haired old man. :cool:

Surely if i keep nutes low and make sure i have sufficient runnoff every watering then that should stop salt build up shouldnt it..

Yes it will but you will also get small plants and smaller yields, plus more problems than feeding proper strength.
