Help! Hydro going bad..

[EvilJonas]

Plants are yellowing and quite close to dying this started from bottom and is moving up.
This started right after seedling stage and is still persistent.

Ph 5.5-6.2
EC 0.5-0.8
Added epson salt quarter of a teaspoon.
Lamp is 1.5m away

you're either not feeding em, or your roots are all fucked up.

Im using complete advanced hydroponics of holland pack as food.

In 10liters of water:
4ml grow - 2ml bloom - 2ml micro + enzymes and grow booster.

Just added 2ml of grow so theres 6ml as of now.

What are you running for a hydro set up. I'm gonna go with your roots are jacked.

 

[EvilJonas]

Roots that are visible at the reservoir are shining white I take that, that they are healthy.

Hydro is flowgrow 500 and medium is Canna's glay aggregate.

Lamp is too far away

what kind of water- tap (if so what is ppm)?

Does the directions tell you to mix veg and bloom nutes? Not normal practice, especially at this stage of growth

Depending on which EC scale .5- .8 could be 2xs more than you want

Go here and click on the pic that resembles the same as yours.
There will be more pics inside and the solution.

how much is 10liters? i don't speak metric. if that's more than 1 US gallon then you aren't giving your plants nearly enough food.

for comparison. i use 1 quart pots with soil/coco. i think that's close to 1 liter right? when i feed my plants using General Hydroponics. the label says 5ml per gallon i use anywhere from 5ml to 15ml per gallon depending on growth. for how big your plants are i would probably be at 7-10 ml by now. i converted it to metric with google...i hope i did it right...

but even at basic rates for 10 liters of water i would be feeding my plants 13ml of either or both bloom and micro/veg formula. i use a 2 part solution so in total i would be using anywhere from 26ml to 52ml (i never use more than 20ml per gallon combined at any stage) for 10 liters of water like you're doing.

i don't know how similar Advanced Hydroponics is to General Hydroponics, but like i said your plants are hungry for one reason or another and if you say the roots are fine then i would feed them ASAP. it's possible you might be too late, i can't tell with all that yellow light, but it looks like all your leaves are yellow/white = dead. i would empty the res, fill it back up with double the food and wait a week. DON'T CHANGE ANYTHING ELSE. i doubt your lights are an issue or else your plants would not have grown this far or would be about 5 foot tall with 1 foot between each of the 5 nodes on it.

according to this chart you should be using anywhere between 7.5grow/3.7bloom/3.7micro to 15grow/7.5bloom/7.5micro (per 10 liters) at this stage. you're using like half that baseline minimum.

in 10L of water id put in 20ml of bloom 10ml micro. with my water starting off at .4 this brings the overall EC up to around 1.2 or 1.4 im hving a stoned moment and cant remember but you get the picture

they may be hungry, feed more and always double check your ph meter and then check it again.

How old are they? Honestly they look a little young to be starting nutes. That could be part of the problem?

???? please clarify... no nutes would equal clear water and that won't work either?????

?? Im saying feeding a seedling with to many nutes to fast. That could be the problem.

10L is basically 2.5 gallons. the conversions greengrass gives should work if that is what's going on.

 

[GreeeeN GRassss]

sorry i should have mentioned that my plants would be larger when im feeding them that nute solution. i was just giving an example of how much i use so he can compare levels etc.

increase feed and check for color coming back and watch out for nute burn.

you shouldnt need to use epsom salts. the GH nutes will have enough of everything the plant needs at this stage of growth. try giving 5ml of micro and 10ml of bloom for a few days and see how the plants react. maybe change out your res but i dont use hydro im growing in coco

 

[GreeeeN GRassss]

check this thread out. gives you a guide on what nutes to use. i was trying to find H3ads 6/9 recipe but i couldnt find it. but i just use 2 to 1, 2 parts bloom 1 part micro.

I figured it out whats causing the problem...

My hydro pump is causing the reservoir water temperature to rise and the temp is around +/-35C

Problem: Dysfunctional reservoir pump is causing the temperature rise too much for the roots.

 

[stihgnobevoli]

i don't think that's it. you said the roots were fine. if the roots had been that hot that long they would have turned to brown mush a long time ago. but if you're convinced that's the issue. Glad it's'a resolved.

 

[b3fr33]

I'd say change the nutes to a simple and good 2-part, as I tried Gen.Hydro 3-part and didn't get on well with it really

 

[EvilJonas]

What does it mean?

I have Advanced hydrophonics of holland. Grow Bloom and Micro.
How would I apply 2-part nuting with the nute set I now have?

 

[Waterlab420]

How old are the plants...
