Rusty spots on the leaves Plz

permalink
leaves are 30% rusty ,,, like they have heat stress or nute lockout,,,but

Heat is fine at 80F-89F
PH always 5.8-6,, all feeds checked befor feeding
Nutes are at 700ppm- 770ppm whn water is taken

i will try get sum pic up in 30min or sum

Put the pots are to small i will be transfering to 10ltr pots later aswell,,

Would the small pots make them look like that?/??

Thanks

any 1 any ideas plz

I feel stupid for my post......don't mind me if you got to read it before I edited.

Lets see some pics. Rusty you say? Sounds like the beginning of mg and ca defficiency.

if you spray your leaves with water the heat from your lightsource could cause burns

ya but not rusty colored burns more of a yellowish burn.

Do you have multiple plants in one container?

I have transplanted all the plants int 10ltr pots and ,, ( they were always growing separately )

Im using pelite and clay pebels as grow media

as iv said

• PH= 5.8-6.0
• ppm=700
• temp=80F

Any info please thanks a lot

The size of the container wont do that.

Check this out, I think this is your problem.




How old are your nutrients? have they been stored in the sun?
Thats all I can think of

Good luck

how is this possible ??

i'm using

Ionic Hydro Grow,, thort they would have all a plant needs,,


and i change the water regularly,, wouldn't the new mixture have the right amount of nutes needed???

i had same problems....i flushed for a week with water.....settled down on nutes . then watered regulary turned out fine after nice green foilage

its almost as though your ph meter was broken. they look bad.

yea that may be to be honest,,,they are bad ,,, i need to buy a digi meter for the phing,, using stupid drops

i will see what happens ,,,,

I second the Mg defficientcy diagnosis but here is link to some good problem solving information.

Trust me, yes it is a seed site, but the page I link is to diagnose problems.

looks like mg def to me....add 2 tsp epson salt per gallon and it should free up the mg and cal....

Dunno, maybe you need extra when you are doing strictly perilite?

about the epsom salt thing, if it isnt a mg deficiency, and you add the salt, will there be any negative consequences?

wana know this too,,,, and were i would be able to get sum,,

Could be its really high in sulfer. Get some of the CAL MAG boost that botnicare makes saw it at the hydro store today accutally. I had this problem with hydro thats why I went to soil, to learn and then am going to slowly go back to hydro.
