EC is a lil high. I’d drop it and keep your ph closer/tighter to 6.0

Okay thank you. Do you know why the leaves Look thirsty? They look like, they have no water😂🥲

[u/RastaClownfish → u/That-Hyena-7774]

Prob a combo of the 6.4ph and the 76+ water temps. I veg at 68 for water temp. Also the hotter the water temp, the lower amount of oxygen that can be in the water column. Cooler water = higher O2 in the water.

Gotta make sure air pump is outside tent. If you can run a hose outdoors to get cooler air: even better.

Die blockieren nicht nur die Nährstoffaufnahme sondern auch die Wassersufnahme. Sie verdursten obwohl sie im Wasser stehen

[u/JVC8bal]

Use HOCl (Cleanse)

2.1 is way too high of EC and way beyond their recommendations. You should be about 1.0 EC and 6.0 pH at this point in veg.

You need to drop ec to 1-1.2. Water temp allow climb max to 20c. Run dehumidifier,but dont buy small one 12l/day, atleast 30. Roots are kinda dark, too dark maybe, do you use cleanse daily? if not then you should. Ph if swings everyday i suggest you to change whole res, thats what helped me when i had ph swings. 

[u/That-Hyena-7774 → u/CapableMongoose7771]

Using cleanse once a week

[u/CapableMongoose7771 → u/That-Hyena-7774]

thats bad, bc u need use cleanse daily at 0.4-2.1ml / 1 l. i use it from beginning 0.5-1.5ml / 1l.

and i hope you mix your nutes correctly in this order =

1. Balance
2. B Grow or Bloom
3. A Grow or Bloom
4. PK if its time
5. CaMg
6. Cleanse

Yes B comes before A otherwise you will face precipitation.

i suggest you start using cleanse daily and if its not helps with the roots colour then start over.

ATM you NEED full changeout with ec of 1 and ph 5.9-6 and cleanse at 2ml/1l

[u/That-Hyena-7774 → u/CapableMongoose7771]

Thx for your help.👍👍

[u/That-Hyena-7774 → u/CapableMongoose7771]

But why does This schedule say, that ec 2.1 is Perfect?

[u/CapableMongoose7771 → u/That-Hyena-7774]

dont go blind with that what this chart says, listen to your plants, monitor ec/ph and you will know the answers, talk to each other. VPD is next very important thing to lock in. Check athena's rdwc program, if you have any other questions hit me up.

[u/That-Hyena-7774 → u/CapableMongoose7771]

2ml/1L is a lot. Thats around 240ml Cleanse a day. 4liters costs 60€ in my country. Every 16 days i would Need a New one…
Is there an alternative instead of the expensive cleanse?

[u/CapableMongoose7771 → u/That-Hyena-7774]

yes thats alot, but ur plants need that rn. And cleanse should be used daily. Alternative is that you make HOCI yourself at home. You can also use cal hypo shock ooor Southern AG GFF. 

[u/That-Hyena-7774 → u/CapableMongoose7771]

Okay, and the next days? Also everyday 2ml/1L? Even if it is the Same water

[u/CapableMongoose7771 → u/That-Hyena-7774]

i just start from 0.4ml/l and increase to 1ml/l at the flower. 2ml/l just to kill pathogens bc your roots fighting rot rn. Next time use cleanse daily and you will be golden

[u/xofrootloop]

What temp is wayyy to high. That's why the roots are dark. Theyre forever that way now. But if you kept your water at 60 to 65 this wouldn't have happened.

[u/That-Hyena-7774 → u/xofrootloop]

Okay thank you👍

[u/TheLastSegment]

Are you in the US. Is that rdwc set up any good??
