OK, check this.
From the very start I have struggled to getthe Ppms correct and to make the plants grow fast and big like they should in hydro.
In my earlier hydro tests and studies I found that if the adjusted EC drops the solution is too weak and if it rises it's too strong, more or less, yes?
I started mild and went slowly up the whole time and in every single adjustment, no matter what the EC was it was always a bit higher the next time checked.
I went like this all the way up 800ppm or something. Not always just rising the EC but sometimes making it weaker again and same thing, next time checked it was always a but higher. Untill I dumped it and started all over again.
Whole time my Ph was very steady, only small adjustment needed occaisionally.
Plants never really did the growth what I expected.
Now that only thing thats been steady,Ph has started to drop quite fast.
In this nute solution what I have now running the EC is still low but I'm getting it up like before just to see if theres a reading the plant likes, doesnt seem like thou.
I came back from few days visit to the city and this is how its been since:
29.10 Ph 5.1 (down from 5.6) and Ppm 486 (up from 477)
30.10 Ph 5.2 (down from 5.6) and Ppm 492 (up from 486), added a bit PK13/14
31.10 Ph 5.3 (down from 5.6) and Ppm 511, added GH3 nutes new Ppm 591
1.11 Ph 5.3?, not 100% sure (down from 5.6-5.7).
12h later
1.11 Ph 5.4 (down from 5.7) Ppm 597
12h later
2.11 Ph 5.0 (down from 5.7) Ppm 609
This is where I'm now. Now I rised the Ph to 6.1 and will see where it is after 12h.
I found out/read that sometimes the Ph starts to drop after flipping and changing to flowering nutrients because it takes all the N in this time and theres less of it, or something. And I actually experinced this on earlier in other place and got it settled by adding N.
This cant be the case here. It's mid flowering now and the plant is very green. I actually gave this one too much N at the beginning of flowering and I think there still might be too much of it.
Any ideas????
Thanks
It has grown a bit by the way.
