Bruising or nute problem?

Sorry, she is more in like week 5 of flower rather than 8. It was a bad judgment call, she had a flower here and there but was in pre-flower for like 3 weeks...She still has maybe 3 to 4 weeks to go. I changed the diary to reflect that. I find the symptoms weird, because the deadspots appear only between veins, never on veins. Some edges are appearing purple/red, as do the spaces between veins before the damage sets in. But you really guess its a defficiency rather than a toxicity?

Hi mate, Looks like that start of calcium and phosphorus deficiency. However its not something I'd worry about this late into flower as she will be using those nutrients for fat flowers. If you feel like trying to sort it out you could add a little CalMag or a teaspoon of agricultural gypsum (calcium sulphate). Make a banana brew to give her a boost. Lots of natural and organic ways to help that won't affect taste. I hope this helps, good luck and happy growing.
