Thanks multiVortex... I figured that was coming! Well that sucks a plenty, sadly I must shelve the hempy grow for summer. I’ll run these autos in soil now.
I’ve got blulabs pen & calibrate juice, ph up & down I know the basics but suck at hydro stuff.
How do you beat ph drift? Let water sit out? Do you mix fresh nutes each day? What strength is your nute mix when you feed every single day? Then feed 2 X per day in flower?
Sorry for questions You don’t gotta type a lot - if you know a good link I’d be stoked!
Bluter will be better at answering that to be specific to your situation as I recirculate mine. However, I should be able to get you to third, and Bluter can bat you in with some tweaks.
Since you’re watering by hand, I would mix it up once a day. You could even mix enough for two days. Check the pH before you feed, no problem. What happens in the container happens in the container.
Feed strength is the same. Not sure what you’re going to run for nutes, but keep it within normal boundaries and you’ll be ok. For example, if you were running the gh trio, an stuff, etc, standard “half the amount listed” applies. If you were to run mega crop, maybe back it off a tick and watch your leaves like a hawk. You will probably need calmag. I've come to find that I need to start the calmag a little higher than I had been. Right now I'm 2.5ml/gal for week 1, then 5ml/gal from week 2 through the flip, and through week 4 or 5 in flower shorter flowering times are through week 4, longer is through week 5. For the record, the calmag I use has
zero nitrogen. (Organic from True Plant Science.) At that point, I back it down to 2.5ml/gal. However, I'm in the middle of working through this, but with RO water and LED's, I've found that should be enough. Get it dosed hard for a while, and get it building up in the cells.
For a seedling, until the roots become established, you may have to water more frequently. Depends on size of container, etc. If solo cupping it initially, it shouldn't take too long for the roots to get down. The perlite will wick moisture though, so that helps.
