Early veg stage using jacks 321, promix hp, checked runoff ppm 2850, shoud i give plain ph’d water next feed and check again or what to do?
Without any additional info that what is supplied, you should be around 800 ppms. I would water with Ph’d water only until the ppm drop to below 800 and then feed. Maintain 800-1000 ppms until flowering.
I am not familiar with Promix but I assume it is in the coco realm so is inert?
Ok thank you it will be 3 days before they need another drink so I’ll do what you suggest
Yeah, it’s just a support media like coco. Holds moisture better but the HP (High Porosity) keeps the medium loose and airy.
I don’t go below about 1,500 ppm runoff before resuming nutes. That said; in Autopots I don’t bother and sure the medium is loaded with salts but no issues.
So your saying once i get the ppm below 1500 mix up a few gallons of jacks 321 again and feed but until then just use ph’d water at a ph of 6
I haven’t seen any issues with feeding Jack’s every time. I do go to water only the last week or so.
