    Default Deficiency? Hopefully...

    Hoping these are mag/cal def not overdose. Only had a small amount of magne cal, 0.5 ml perr ltr at the start of feeding, one time. The ones affected are being fed Plant Magic hardwater grow/bloom.

    Been feeding since the 10/8 so I imagine 3-4 feeds of mixed grow/bloom then to bloom only, of 2ml per ltr, usually take 3 ltr, could probably go 4ltr now on the bigger pots. Due to be fed today, so need to check this out before I do.

    Had a pm organic mag granule mix during veg. Under led 240w aray and 150w IS

    I’d go for excess, MrC.

    That PM Magnecal is very strong. I had an od using less than that in water with an Ec of circa 0.2.

    I’m pretty sure the PM grow and bloom nutes for hard water practically make the need for additional cal and mag redundant but that’s just me looking at it from the opposite situation to where I grow.

    Did it show up quickly after you fed Magnecal, btw?

    Did you have any symptoms before you fed it?

    It was early on so all plants were clean, totally forgot, was on auto pilot lol. I remember us talkin about magne cal before I started this grow. So do you reckon a flush? Didn't occur to me what a ballache flushing would be with this grow but if it needs to be done.

    I’m not sure I would flush at this stage. I’d just crack on without the Magnecal and see if it worsens in any way first.

    Herb may be on point here, it happened to me on my first Blackberry grow MrCannab1sir...do you know how hard your water is? ..check with your water supplier if you don't, most (but unfortunately not at all) have an online option to check via your postcode.

    Could be calcium toxicity if your water is medium to hard and you're adding even the smallest amount as a supplement


    I'd always add magnesium separability in the form of epsom salts..

    Waters harder than Mickey the pikey lol, so it's most likely the case. Do toxicity generall go brown and die and deficiencies drain from green to yellow and die? Is that a good rule to go by do you think?

    Yep. That’s exactly what I mean.

    That said, it doesn’t look too bad, MrC.
