Wow, reckon you've been flamed before then... :) Soil, not sure what strain or what percentage in/sat. Bio buzz, 1ml bloom and 3ml veg per L water. Feed every other watering every other day, 4x80w hans panels.

The marks on the leaves are quite pronounced, can't believe no one has ever seen this before? I'm going with MG deficiency and adding epsom salts to a foiler spray and flushing the soil through with 20 l of PHed rain water.

Thanks for your help...

Yeah some problems just appear over night and just keep advancing quickly.

Just keep an eye on your PH, make sure it's stable, and watch your leaves closely the next few days. If the problem continues advancing, we have a little more work to do. If the problem stops advancing, then you have it all fixed up. Most problems won't be repairable, in terms of leaf damage, but no need to cut them off. Let them keep working for the plant, as they have stored nutrients the plant can use.
