I can't tell exactly whats going on.. is it magnesium deficiency? 2 different strains, same thing happening. Dark green fan leafs= Alien OG, light lime green leaf is Cherry Pie. Started with plain watering with crystal geyser water (investing in R/0 system asap) for about 3 weeks left for 2 days, got back and they were looking sad, not as sad as the pictures but sad none the less, soil was not believed to be under watered or over watered at that time......(Minor tip burn?, the veins are still a dark green/purplish color, while in between is fading to a yellowish). Symptoms didn't improve after 2 days so i started with a feeding at half strength camag+, biothrive Grow, bio Root, as well as bio weed from the GO line. 3 days later and the pictures are where they're at.
The things i am seeing are..starts at old growth and works it's way up, leaf veins are still dark green/purpleish, but in between is yellowing, tips of leafs are burnt and sides of leaves some times start with a brownish spot and develop into either burning the sides of the leaf off, eventually leading to about half the leaf getting engulfed by the brown spots taking over and gets toasted and falls off on its own or just staring at it makes it come off.. the other thing is some of the stems are purple and some aren't, as well as some fan leafs showing the top part of the stem to be purple and the other side of the stem (facing down) to be green or sometimes pale in color.

I'm assuming i messed up in the soil department and the black gold with just castings didn't have enough, "juice" if you will to keep them healthy that far into veg? Was the only soil i could get my hands on at that time, but i plan on switching to a new more amended soil called empire builder.

I know i messed up, but i can't seem to pinpoint one exact deficiency..it looks as though i caused a magnesium D, or possibly a potassium D?....sulfur D? Both? All 3? None?!Help, please!!!! Thank you kindly for your time and thank you in advance...great community.

1st pic Mg-, 2nd pic Mg-, 3rd pic wobbly, 4th pic Mg-.

That's my opinion.

Thank's Seamaiden, i initially thought that, but then as i researched more and more all the deficiency's seemed to blend together and i couldn't pin point exactly what happens. Sorry for the 3rd picture being wobbly, i was trying to show that the new fan leafs at the top are pretty healthy but that the dark veins of the plant and the color in between the veins is starting to dull a bit. Thanks again Seamaiden. Input is still welcomed for this nooby. Thanks guys and gals.

Super easy way to tell if it's Mg- is to get some Epsom salt (MgSO4) and dilute at the rate of 1g (or 1tsp by volume, this is how I measure it) per 1 gallon water, and add a few drops of soap or something to act as a sticker-spreader, then apply as a foliar. If it greens up within a day or three (three at MOST usually), then there you have it, plant's short on available Mg. If not, then you have an uptake or utilization problem that would need to be further teased apart.
