Overfeeding?

[Merkn4aSquirtn]

What are you growing in?

Coco

 

[Gastheblast]

At first i was using there 3 in one and said ph was at 8 then bought this one and said 7. Now im wondering cause i got clones in a coco perlite and just tested it and says ph of 7. I feed at a ph of 5.5 in my coco

Not trying to be rude but I would not trust that meter.

I wouldn't even worry about what a soil ph meter says, not accurate at all.
Have you checked your ppms in your runoff?

My runoff was at 950 last feed so i flushed it. Gonna water today and see what my runoff is today

K well i gave them water my runoff is at 900 ppm again even though i flushed it till it read 300 ppm and my runoff ph is at 6.0 stable

This is what I experienced as well

Ya this soil holds to much salt. I just flushed it till it read 250 ppm you think i should give a bit of calmag or wait till it drys again

So are you running soil or coco I got lost...? That cheapo is useless at all.

 

[Bukvičák]

And how you measure your runoff pH? Hope not the same way...

Happy frog

No i have a good ph pen lol

Okay then I can only say, that flushing soil to the EC 0,5 gives you always pH around 6,0 because its peat based (flushing coco gives you 7,0 ). Do you use tap or RO? Use calmag only if RO and not too much. This is probably K def ruins your leaves so rise your feed to EC 2,0 and look what happens. Also aim your feed and water to pH 7,0 since your soil is pH 6,0... maybe start to think about top dress your soil with dolomite lime to rise your soil pH (if it has time to take effect). Thats what I would do but maybe I am not right. Good luck

using tap water that has a ppm of 170

That's depends on which one you have.

True. 95% of new growers won't be starting with this tho lol

What's the time to stable pH reading for that pen? As it happens, I'm in the market for a new unit. I hear great things about Bluelab, so my sight is in that direction currently.

Ya I bought the cheesy green one off Amazon at first. I tested it and compared it to the drops, and that thing was way off. It went back right away. I finally got tired of guessing and bought the BlueLab one.

 

[Flatrate]

Besides my lights the Blue Lab soil pen was the best thing I bought for growing!

It's gives a pretty close reading instantly, but after a couple minutes it seems to be totally stable. I haven't used it a bunch yet. But it makes it really nice if I want to actually know what my soil pH is. @Renfro is the one who recommended it.
