So the last few runs I've had this problem and I don't know how to fix it. Here is a summary with pics...
well into veg, can't flip until I cure this...brown&brown-yellow edges spread inwards eventually browning and killing the whole leaf, claws both up and down but not crispy; soft leaves.
Canna terra pro+ and perlite medium
I was feeding H&G as specified, then tried GH briefly, now I'm trying canna, still getting same issue feeding as recommended. I suspect it to be magnesium deficiency/lockout, but I'm not sure why. Just tested my run-off and it was ph 6.2, ppm 1150... ph seems a bit high and feeding too heavy also?
I have tried to water at ph 6.0 and go by the bottle...
I know it's not pests or the roots or heat, so that leaves ph and ppm right? Arrrgh... I've messed up 2 flower runs like this and now this veg is going south, makes me think about doing a pre-mix like subcool's and ditching soil-less with liquid ferts...
What to do??? I sprayed w/epsom salt, thinking about flushing and refeeding at lower ph&ppm...TIA guys!
