Alright, well, I've read through all the stickies, as well as a few other pages, and I'm not quite sure what the problem is here - it's probably calcium/iron/magnesium/zinc, but I'm not sure, and I don't want to start acting on a guess. Recently I noticed root issues, and a couple plants wilting from the bottom up - they were removed on the assumption that it was mould, the reservoir/roots washed with a solution of h2o2 and tap water, flushed it all out a few times, filled up with R/O, Cal/Mag to 150, Maxibloom to 1300, and then Pro-TeKt to PH, along with a gallon of beneficials in tea form. Since then things have improved.
The leaf spotting was not apparent then, and I only had time to look at it yesterday. Iron, zinc, calcium, and magnesium all mention chlorosis between veins which remain green. Mag seems the least likely, as it should have effected lower leaves first, and while I've lost a couple of the lowest fan leaves, they are decidedly healthy on the plants which show this bleaching on top. Calcium mentioned internal issues and root mass die back, both of which happened recently, however it was assumed that this was due to mould or another pathogen...
So, I have a general idea about what's wrong, but it's only that... any advice would be greatly appreciated!
Current PPM: 1100
Current PH: 6.1
Adding back 200 PPM would bring the PH down to about 5.8-9, however I don't want to make any moves without getting a few responses, thanks! (Root shot from a plant removed previously, as mentioned above, just in case there was no pathogen, and simply a nutrient imbalance.)
