Hey farmers

Fuck.. I have a problem that is killing me. For years i had access to botanicare line of nutes and never ph´ed my nutrients. and that is gone and stupidly or smartly started using a ph pen with gh 3part at 1ml/l micro. 1ml/l bloom. 2ml/l grow. with silica .4ml/l and calmag .8ml/ liter currently in the 4th week of veg.

coco/perilite 60/40 mix

Why did i start to use a pen? After using gh 3 part i noticed a weird change in the leaves. freaked out and bought a pool ph kit. was blue, like 7 in the rez

went to buy a cheap pen. ok. flushed the shit out of them with 5.8 water. ok. recovered.

since then 7 days ago. i do feed feed water. trying to keep the ph of solution i use at 6 on the pen.

now they look like shit again..

so. slurry test on 8 pots this morning and with low readings.

5.4 to 5.8 majority at 5.5

the problem i have is that my ro water comes out at ph of 6.0

Is that still ok to run a slurry test?

why would my ph be so low in the root zone, if the test was even accurate.

My plan today is to flush the shit out of them again ph water 6.2 and then the last watering a full feed at 6.0

I just totally feel like im missing something with this. but my pen is correct. I when i make nutes i let it sit 24 hours in bubbles. and before i feed ph.

any help is greatly appreciated

You're throwing your plants for a giant loop. Feeding them only water for a week is going to do more harm than good. Instead of figuring out the problem you just make it deficient in everything. That solves nothing

Slurry tests r a waste of time

It's the only way worth testing when it comes to coco...

Don’t flush. Just make up a batch about 700 ppm and run a good amount thru.
Put your calmag in first until 150 ppm then your base to 700 total. Make sure ph is 6.0. It will give you a little buffer.
Make sure you run that thru and do not let it dry. Every watering get a little extra runoff. Should clear it up. Look at new growth not the old leaves. They won’t repair.

Then take a shot of calmag for you and on with your day!

a shot of calmag for me!! whoohoo!!

I have a rez ready to go with 1.5 micro 1.5 bloom 2.5 grow

ph is about 5.8 but i can bump it to 6.0

.4 silica .8 cal mag

silica went first. then cal mag

then 3 part

Is this ok or should i make a new one?

Never feed coco plain water. Period. You need at least a low ppm like 200-300 to keep the cations filled.
Otherwise the coco will start exchanging the cations for other elements and throw it out of whack.
The K will exchange for Ca for example making people think they need more “calmag”. You gotta keep those cations full and you will stay deficiency free. The cations will take what they need to stay balanced.
Once you dry out or feed plain water you start messing with that process
