I've been reading around but can't seem to pin point a solution.

I'm growing in DWC 5gal bucket. Using "Sensi-1" grow powder from AN.

I'm keep the humidity around 40-50% and the temp. at 70'F

My plant is still in the veg stage and about 4mos old.

It seems like a common problem. "Rusty" spots appearing on bottom fan leaves. Then fan leaves dry up or curl like ram's horns. Later the fan leaves fall off.

I've seen many pics here that are very simular to my problem. Here is one link Plant issues, (lots of pics) Need EXPERTS!

The problem started at the bottom and worked its way up. It started to spread on the other leaves. I cut all the lower branches off...changed the nutes and the plant has recovered.

Now I'm starting to get the rust spots back on the bottom fan leaves . So it seems like the problem is starting over again. Also, I'm noticing the same spots/problems on the clones cut from this plant. The clones where taken from the upper healthy parts of the plants. Clones are 1 1/2mo old.


Please, any help would be appreciated. Thank you.

sounds like a mag/cal deficiency


peep this site out this will help.. im sure it will did for me when i had your sounding problems.

International Cannagraphic Magazine Forums - The Complete guide to Sick Plants,pH, and Pest troubles!

Thanks for you help Roulette. I'm gonna get some Cal/Mag supplements and hopefully that will fix things. Can you or anyone else confirm this is not an infection or fungus problem that will spread? I seen this problem, in other posts, referred to as "Rust Fungus".

well i cant say without seeing you plants but from what i just researched on the "rust fungus". it seems like an a raised infection. 90% of the pics ive just seen the rust fungus was spores that where on the leaves.. if you have just little orange an brownish burn marks imma stick with the though on its a mag/cal deficiency.

Thanks agian....I just ordered some Technaflora MagiCal... its on its way. I hope this does the trick.

thats the shit i used on mine when i had that same def an was cleared in 3-4 days.

or i should say the problem didnt get worse an stopped.

the damaged leaves will never go back to the way they should look, just stay the way it is but problem wont get worse or spread. let me know how your shit turns out bro

man if your using that shit use the whole product line.. they have a $19.99 starter kit that comes with thrive alive b1 red and green. awesome blossom. bc grow bc bloom. and a clone rooting gel.. shits tit.

after i had the same def problem as you ( sounds like the same) i bought the magical an i grabbed sugar daddy

Yeah I've been looking into that line of nutes but I use 1Tsb of H2O2 per gallon of water and I don't what products would be "killed" by the peroxid.
