Symptoms: brown spots that originated in the lower fan leaves and have taken over my plants.

Causes:
-Mold?
-Mag/Cal?
-Root Rot?
-?!


Initially I thought it to be a disease/mold in my room (as my water clones grew mold on the stems before they rooted ). So I sprayed with Neem oil, and watered with hydrogen peroxide. I transplanted them - realizing my previous buckets were too small and realized that they had started to become root bound. I believe I had also been overwatering them, since after transplant I gave less water to some and more to others and the ones that received less look perkier. I also have nuted both sets with varying degrees of Epsom salt. One set got one dose of epsom salted water, while the others got two. Initially the epsom salt looked like it benefited the plants. But the spots were only slowed at best. There might be slightly less spotting occuring on the plants that recieved more, but it still persists.

I have read too much Mg causes too little Ca? And that mg can definitely be over done. Should I use more or less mg? Or more Ca?

Also, I believe the rootbound combination with over water may have developed root rot. I have been watering with hydrogen peroxide, however. Could this be the cause of the spotting?

Seriously need some help here... thanks...

how old is that plant bro?

Old.... several months?

Sorry to repeat post. But bump for info and some more information while im at it:

soil grow, transplanted from 2 gallon, to 5 gallon buckets, fertilizing with 10-3-1 guano, 20-10-20 orchid food, a little root stimulator, and a dose/or 2 of epsom salt.... like I said before, several months old.... under a 400w mh, then 600 hps, now 1000hps

looks like it could be over watered. is that bucket heavy when you lift it? you need to let it fully dry out between watering.

yes sir - i was definitely over watering for a couple of weeks - is that the cause of the brown spots though?

over watering can cause brown spots.

hey nugz. I've missed you in my grow journal, welcome back.

I've learned to keep it simple. most of my troubles have originated from over watering.
but, also, from water related stuff, like water being too cold or ph being off...combine those two and you'll be in trouble within just a few weeks.
I'd say over watering in combination with being root bound was your initial problem. a transplanting tip for a root bound plant is to take some scissors and cut the bottom of the root ball a bit when it's between pots. this will terminate the circular growing pattern caused by a small pot and stimulate new root growth. you may need to cut the sides a bit also, if you really see lots of roots growing in circles.
for now, I'd stop watering-make em beg for it...and cut back on your nutes, until the plant has recovered.(the spots will not go away, it just won't get worse or appear on more leaves...but, it may take a week or two)
good luck. I'll check back to see if you got it under control later...
