Legend, easy doneStop the magnesium. Plants don’t need much. Especially at this stage with fresh soil. Magnesium interacts with phosphate and potassium and causes your problems probably.
Here is the Mulder’s chart that would back up my reasoning.

They are getting ready for some bigger homes, but they look pretty good to me. It's pretty early to be seeing any type of deficiencies, especially since you are feeding every few days. You didn't mention what you are growing in? The bottom most leaves often turn yellow and die off due to lack of light. If they start turning yellow and it is moving up the plant, it usually indicates a Nitrogen deficiency. In my experience, unless you are going hydro, the chances of seeing any basic deficiencies other than Nitrogen are pretty rare. Any type of solid medium...promix, foxfarm, potting soil...they all usually have enough in them to allow things to get started and finish, although not with stellar results. Promix is probably the one with the least amounts of nutrients in it. It actually takes a very small amount of nutrients to feed them. I think the stress of topping and slight rood-boundness might have caused the problems that you see, although they look pretty good to me!
Try not to be too concerned about runoff ph from soiless mix honestly. Coco/hydro, sure, but soiless runoff ph can sometimes be very misleading. For ph just focus on what's going in. Too often people get freaked out by the numbers coming out of the pot and make drastic unnecessary adjustments when testing soiless runoff. Sometimes to the detriment of the plant.
I'm not sure if I'm confused or you are lol. They are in a soil mix mateTry not to be too concerned about runoff ph from soiless mix honestly. Coco/hydro, sure, but soiless runoff ph can sometimes be very misleading.
Lol, I'm saying I would only bother to check runoff ph in a hydro setup or coco grow. Since you are In a soiless mix i wouldn't bother because the runoff ph can be very misleading, and often cause growers to chase a red herring trying to fix a problem that doesnt need fixing. Of all the soiless growers I know, we all check input ph and ppm, and runoff ppm. That's it. Making changes to the feeding based on runoff ph can often cause more problems than it solves in soiless mix.I'm not sure if I'm confused or you are lol. They are in a soil mix mate
Haha, fuk it was me who was confused man. I had way too many beers and Doobies tonight lol. I got this thread and another one confused, my bad... you are in soil lol. Gotcha.I'm not sure if I'm confused or you are lol. They are in a soil mix mate
ive heard the viable method for ph in soil is to do the slurry method. takes about 20 minutes to complete. slurry test i was .4 lower than the runoff test -- same water both times
or buy the $130+ soil ph pen
Deficiencies and generally correctable with a simple PH adjustment and not by dumping more food at them..
Yeah ill be doing that this arvo after work to confirm the ph. Cheers !ive heard the viable method for ph in soil is to do the slurry method. takes about 20 minutes to complete. slurry test i was .4 lower than the runoff test -- same water both times
