Grow Mediums WILMA - confused help!!!

[BigAz]

hi everyone,

So I'm at day 62 on 4 DP AU's. All ok so far and putting weight on.

However over the last few weeks I've noticed my EC going from 1.7 to 2.2 over the course of a few days as they feed. They are on a 4 pot wilma XL and fed 15 mins every hour. (20/4). Bottom leaves due to lack of lack browned n fell but the tops are showing no sign of stress.

I automatically thought they were nute blocked. Can't think of anything else.

Hopefully someone on here will shed some light with a bit more experience.

Cheers

Hi man i have not used a Wilma system before but i know people who have.
@sanguine he should be able to help.

Ec going up should mean your feed is too strong. They are taking the water and not the nutes.

Yea as @Anasazi said its normally cause the plant wants to slow down on nute consuption. Have you calibrated your ph pen recently.
Lockout would cause it too

Is lockout as bad as it sounds. Calibrated both ph and EC pen a few weeks back. I'll do it again first thing in the morning.

Lastly with the wilma set up: as you know, it's pumped in from the res below. so how is the plant taking just water with no return back to the res?

Strange

Do autos start to ease off on nute absorption from around day 60. First auto grow

From my experience they do ease of on feeding later into flower. Are the buds well developed? I only ask as auto ultimates can go much longer than the normal 10-12 weeks for autos.
What nutrients are you using

hey sang doesn't your ec go up when I was running mine the ec always went up I thought they always did in a recycling system but I was also using coco

 

[woody]

@Wile e Peyote yea it usually drifts up a bit but 1.7 to 2.2 is about 250ppm on my ppm500 scale thats a bit of a big jump.
Unless im converting it wrong.
I just top up with plain water when it jumps up too much

Using GH 3 part, bud candy and overdrive. 1 is nearly ready to one being 3 weeks off. Scrooges so can't remove individually to flush? Another issue.

Unfortunately irrelevant of where they are in maturity I have to harvest on June 29th. Long story. How would you approach this???
