DWC PH and EC Issues, Please Help!

[AAGrow]

Hi guys, i have a 4 bucket DWC setup and i am in the last 4 weeks of flower but for the last couple weeks i cant get the PH or EC correct. The PH keeps jumping to around 6.7 every time and the EC is not such a problem but is also climbing quite abit. I have emptied the system twice but the problem keeps happening.
Any help would be great.
Thanks

Only done one dwc run but its kinda similar to coco.

Your ec goes up cuz u feed too much.
Your ph is shifting becuz well its what it does. And maybe your ec rising becuz of instable ph.

My 2 cents fill up res with water let sit with bubbler / circulator for 24h then add nutes. If using calmag it goes first.

Adjust ph to 5.6 after adding nutes. If it shifts up slowly its beneficial. Renew your res once it reaches 6.2 - i did so in my one dwc rub and it came out really well. No deficiencies at all with 5 different plants / seeds

Good luck

What do you mean?

Could you tell me step by step how you make a new res.

How do your roots look buddy, try get a photo
Any weird smells at the roots?
Just making sure all is good down there

My advice also.

My advice also.

Saying that your PH would more likely be dropping rapidly if you had root problems

Hey brother

If your water level is falling and your pH and EC are rising then you need to reduce your feed level. Next time you change out your reservoir cut your feed back by about 20% and see what happens.

Static Rising Falling As above but be aware of the acid rain effect mentioned in note 1. Res change, plus increase in EC.
Static Falling Static Plant eating but not drinking. Not ideal. Lower EC or res change
Static Falling Rising As above but rising ph is a better sign. Lower EC slightly or res change.
Static Falling Falling Falling ph along with falling EC but no drop in water level suggests a res change. Could also be an acid rain effect as per note 1. Depending on other symptoms, lowering EC after res change.
Falling Static Static Perfect conditions. EC and ph are at the correct level.
Falling Static Rising Normal state most people encounter. Nothing to worry about, carry on doing what you are doing unless other plant symptoms.
Falling Static Falling Res change plus a change of EC. Lower EC if over 1.4, raise EC if lower than 1.0
Falling Rising Static Plant is drinking more than eating, lower EC.
Falling Rising Rising Plant is drinking more than eating, lower EC
Falling Rising Falling Plant is drinking more than eating, lower EC. Also, res change due to possible acid rain problem.
Falling Falling Static Hungry plant, raise EC. Very good situation to be in. Nute buffers are working and plant is taking a balance of nutrients.
Falling Falling Rising Almost as above, usually considered almost perfect, raise EC slightly.
Falling Falling Falling Res change. Potential acid rain issue but plant is still eating & drinking. Raise EC on new res.

The ideal scenario you are looking to achieve is where the EC is either dropping slightly or remaining static, with a static or slightly rising ph and a dropping water level. If you get this situation, keep doing exactly what you are doing because your plant is feeding and drinking.
