Someone please give me some opinions please rust spots started showing a day or two ago i was told it was a magnesium deficiency so i watered it with epson salt just a lil while ago and when i went in there some of the leaves were looking like this100_0593.jpg100_0596.jpgcould this still be because of a magnesium deficiency?or what rep for any suggestions:sad:
 
What are you growing in ?( soil /hydro?)
Whats your PH?
How old are the plants ? what stage are they in ?
 
I dunno my ph man the plant is about two and a half months old or so and she is in flowering i am growing in soil by the way....
 
too be honest with you man i have a fan going all the time they dont seem that hot i can put my hand under the lights and it dont feel that warm to me....
 
it might be a ph problem ..try flushing them (that is if you have good drainage in your soil )

are you feeding them any nutes? if so how much per gallon ?


is this curling only happening at the top or is it all over ?

answering some of these questions will make it easier for someone to help
 
No i have not used any nutes in about two weeks...
as far as flushing goes i would be scared to i mean i have good drain holes in the bottom but no perilite sand or anything just the mg soil
the curling at the moment is mainly at the top but you can see it starting all over
does that help diagnose it at all?
 
You have a deficiency. Feed it. Miracle grow is high in N which will take you up to when flowering begins. Now you need a nute high in P.
 
I had a similar problem with that kind of damage for me it was something like o-zone deprivation. I had a fan blowing to much on the plant that it started causing spots like that and curling leaves. So it could be a few things, what kind of soil are you using?
 
i just watered it tonight so i cant feed it for two or three days at the soonest maybe longer this mg shit dont drain very well next time using diff soil and putting something like perilite in it
 
Yea i wouldnt flush then because it would be easy to over water them ...


Could be Mag Def.
Or
It could be Heat stress
Or
Your PH can be Off

Im pretty sure its one of them im leaning towards the mag Def. then i would say Heat stress ...if it was the ph then leaves might be changing colors and or have spots
 
well i just watered it with a gallon of water with a teaspoon of epson salt in it if it is mag def. how long do you think that it will take to see improvements? Because i really dont think that it is heat stress and if its ph i dont know how to fix it im kinda straped for cash
 
if your using tap water just let it sit out for 48 hours with the top off that should give you a neutral PH of 7.0 keep doing it throughout the flowering period since you dont have a ph tester ....I dont think those leaves will recover you just have to look at the new growth and see if you see a change
