my girl is about 2 months old, still in veg. a while ago she was over fertilized (you'll see old signs of this in the pics) and flushed, *i went away for a couple weeks*, she went a little N def and was fertilized with 1/4th strength of some 24-8-16 fert (it's all i had) soon after. a few days ago this started.... it's mainly affecting the older leaves (though it seems most problems usually hit them first)

the first pic was with flash, the others are without and the colors are a bit faded.
the first and second pic are of the same leaf.

thanks for any help!

ps: i just got ahold of FF grow big that i plan on switching to next watering/feeding

the first pic was taken with my camera's flash on and shows the color a little better, but the flash was causing too much trouble so it's off in the other pictures.

i'm confident that they're not being over watered and the soil has good drainage.
i haven't PHed the water in a while, but i've been using the same tap water, distilled for a few days, for a long time and i'd previously checked it's PH to be just under 7

thanks for the reply

That happened to me before, I never figured out what caused it, mine was in hydro, it was a really hot day - I always just figured they drank up all the water then got some sort of nute burn. I just changed the res completely and they sprang back.

Overwatering and PH are out - I hope someone knows what this is because I am really curious.

put alil epsom salt in your next watering and see if that fixes it. it looks like its in need of some mag.


micheal what nutes where you useing when you had that prob with your hydro? alota ppl use general hydroponics 3 part. its a good fert but is doesnt have the cal/mag needed for pot. i use the stuff myself, but i also use cal/mag plus to help it along. if you use epsom salt in hydro just remember alil goes alooong way.

Thanks for the tip - it must be mag deficiency because I started adding Cal/Mag to my res about the time this happened and then it went away.

id say over feeding.this happened to me on my first grow. i fed my girls hydro food instead of terra food.hydro food is much stronger and the plant has to expel the over feeding some how, and i think thats whats happened to your plants. over feeding, dont stop feeding but try to wash your plants if you can. now i always put lots of pebbles in the bottom of my pots to help drainage.keep growing. dont kill them with kindness.the meaner the better ,they will tell you when they need food or water you will just be able to tell after a grow or two.

I'm sure it's a magnesium def. I just double checked, and noticed the fert I had didn't have any mag (i think i mistook manganese for mg when i checked before).

I just got some FF Grow Big which has .6% mg, would it be enough to just use that next time, or should I definitely add some epsom salt too?

i would get yourself some blackstrap molasses....
i use breyer rabbits blackstrap molasses picked up at the local grocery store it's high in potassium,magnesisum & iron..
