Cool, I think that's what it is too. I'm glad cause things have been going so smoothly. Thanksi think what youve done is splashed nutes onto your leaves.
i do this alot as im feeding big pots by hand, it just looks ugly.
Before you consider any serious problem perhaps make sure you dont spill it onto leaves.
even just a splash or a touch of the nutrients onto leaves will cause this especially if its under lights.
Too little or too much you think?Looks like a calmag issue
too little or lock out due to poor drainageToo little or too much you think?
Or what exactly do you mean?
I gotcha, thanks.too little or lock out due to poor drainage
