New Grower Need an experienced grower advise please.

Oh yeah I forgot to add that im gonna purchase a BlueLab PH Soil Pen that measures the PH value and temperature of the soil. Its around 200 euro but I figure its an good investment right now, and for future grows. @Olderfart @Arthur

Hehe no worries mate, probably because I'm growing in autopots, but decided to stay with handwatering. Yeah I think thats the best way to go, for now I'm only gonna use PH water to 6.5 and see how it turns out.

I'm not sure if you are familiar but I'm using Fearless garderners brand of nutrients, and they have an product called "Flush-out" wich they recommend that you use at first sight of nutrient lockout. The instructions says to water until runoff with the solution, then flush with regular water until the blue indicator dissapears (whatever that means?) and the objective with the solution is to get rid of built up salts etc. So you suggest I use that as an absolute last resort?

Again thanks for all the help, and sorry for double-asking some questions i'm just trying to be very cautious right now so I dont mess up my first grow too hard...

Yes will do, i'll keep you posted! Cheers mate! :smoking:

No worries at all about asking for help whatever way works for you, most peeps here, including me, are very happy to help if we can.
As to the flushing product, it may well be worth a try. I’m guessing that it is intended to indicate more flushing needed until the blue colour in your runoff disappears. The instructions will no doubt clarify for you. It is possible that the product enhances removal of nutes from the soil. OTOH, it may just be coloured water.
Whether you use it or not, If you decide to flush, I would pay attention to the ppm of your runoff. You are not done until you get the ppm
where you want it. I don’t know how low you would want to go given that you are using water only on amended soil. Maybe the manufacturer could suggest a target. I would trust ppm sooner than blue dye.

Good luck with it.

Plants would prefer to be fed macronutrients at a lower concentration, rather than receive no fertilizer in exchange for purely CaMg.

I.e. if you're going to dial back on something, cut the supplements and feed a low-strength base fertilizer. Cutting fertilizer and offering only a mineral supplement will likely make things worse.

Have looked at that pen for yrs, at that cost, I keep looking, and slurry testing.

I did two feeds with nothing but PH:ed water, the ppm going in was around 200, ppm in the runoff was around 800 and EC was 2.0, so its getting a little better.

Do you mean I feed them the regular nutrients but very small dosage?

After two feeds of only ph:ed water the EC/PPM Values seems to correct themselfs a bit. Its around 1.8-2/800-1000 now in the runoff. Gonna do one more natural feed and the start her back on the nutes.

Me too. I must have looked at it seriously three separate times, with accompanying homework each time.

If I believed that it would be as durable and effective as my Apera, I would choke it down and buy it even for my small scale activity. The thing that puts me off is the, IMHO, high chance that the probe would not last reliably given the combination of abrasion of soil and the inherent delicacy of pH probes. Maybe I am wrong about my expectation, but at that price, my instincts have ruled so far.

I believe you leave the pointed cap on to make the hole, and then just place the bulbed probe in the hole and water, seemed like a solid thought process... it's just that price... I kinda feel like it needs to at least buy me dinner first.

Yeah, when I get too salted up (happens to everyone, very phenotype specific) I still use the exact same ratios of GH trio, just at half or 1/3 strength from what was causing lockout. I rarely ever feed with "empty" water because it's almost impossible to pH correctly with a low EC.

Hmmm. I didn't realize that the process included watering. That, combined with the prepared hole makes a lot of sense.
