New Grower Need an experienced grower advise please.

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

It's an in the pot slurry tester. Love the idea, not the $! For that cost I can keep doing it the old fashioned way.

Found this coloration on my colorado cookies. Runoff ph is now within range, using nutes at half strenght, feeding them 3L water each every 24-36hours depending on pot weight. Temps have been fluctuating a little the last few days, the winter came crashing hard.

Any ideas on what this is and how I can fix it? @Arthur @low_and_slow @Olderfart

The orange-ish color bits may just be temperature, but the overall light green suggests persistent lockout to me. What are your runoff ppms/EC's? If you do not have them down to ~~1100 or so EC, not PPM, I suspect that they are not low enough yet. If they are down in that vicinity, you may be locked out by nute imbalance from selective plant uptake, cal mag applications, or selective removal of only some of the original nutes into runoff.

In a nutshell, I think you are still locked out from either too rich a mix, or imbalance of nutrients. Where to from here is the important question, and that will depend for starters on where you have managed to get your runoff to.

I spoke with BioBizz and they said that this specific organic all-mix soil shows high ppm/ec runoff and is nothing out of the ordinary according to them..hmm. But last time i checked the ppm/ec it was pretty good within range i think, like 200-300 of what I put in. Havent checked the EC yet tho, will do it during the next watering. Think I should resume nutes or keep at it with regular water? @Olderfart

What is your input EC/PPM? If your meter only does PPM, what conversion does it assume, 0.5 or 0.7? If it can be set to EC, I recommend that you do that.

It does both, and both 0.5 and 0.7

I'm gonna give them a plain watering now, and report back with the numbers.

Should I keep feeding them water for awhile or should I resume nutrient intake for the girls? @Olderfart @low_and_slow

I have to say that PPMs may still be a bit high, but I know nothing about your nute package. Very few people here run autos at the EC of your runoff. My current grow seems to hate anything over about 1.0-1.1, but I am using Mega Crop II in peat. If it were me, especially given my experience with my current grow , I would be tempted to keep watering with water only, or flush with it, to get your ECs down to 1.1 or so, and then see how the girls do with balanced nute input at ~1.1 EC/ 6.2-6.5 pH. In any case, I think you should be pHing your water if you fertigate with water only, ditto if you flush with it. My preference is to flush with nute solution, but lots of peeps just use water.

Keep in mind here that I am new at this, so if you get contrary advice, feel free to go for it.

Good luck with it, please let us know how you make out.

Now I'm puzzled. Your coco was raising pH before, now it is lowering it. Your runoff pH is now pretty much perfect in spite of your input being 10x more alkaline than your nute solution was. I don't know what is going on with pH. Maybe one of the gurus on here have some idea what is up, but I don't.

Hey man just a clarification. I'm not using coco as my medium, im using biobizz all-mix. But yeah I'm thinking of sticking with water untill the EC is where is should be, around 1-1,2. Thanks man and will do! :smoking:

Sorry about the coco miss - another aged stoner moment. I edited my last reply to get rid of my confusion on medium and pH. As far as my morning brain can sort out, I was thinking of another grow on here than I am trying to help with. Maybe another cup of coffee...

If you are dealing with lockout, it may take a while before they turn around. Two of my girls continued downhill in spite of my adjustments, but I now think I did not get the EC low enough soon enough, or perhaps I just let it get too far out of bounds before correction. It seems that sometimes lockout buggers the girls up for the rest of the grow.

Keep us posted on how the girls respond, I hope that they sort themselves ok.
