I am at 3 weeks on my third little test plant. I have a good set up and good RO water in my basement now. My first 2 plants got burned with high PPM but I did not have a fungus/rust problem with them. Now this plant has rust. I applied Neem oil spray and adjusted my temp and humidity, Nutes , pH and PPM are good but now what? If the problem persists is this plant screwed? so sad...help please.
Rust :(

yeah rust is because the RO
it is calcium deficiency
you need to get reverse osmosis/soft water nutrients
some add calmag over regular nutrient formulas to provide the cal but i don't like it

yes
it contains 7% calcium. use the same grow and bloom bottle as usual
personnaly i never liked calmag (cal/mag nitrate). it do not buffer the water properly
i always stick to soft water formulas with RO water
no need to use calmag with these
if you want to use calmag take your RO, add calmag until your read 0.4mS, then add your nutrients

no wonder, different brand, was GH at one point. I cannot seem to successfully search it, does it ship to US. or maybe GH only in USA.

ah sorry, floranova i confused with floraseries
they say floranova work with both soft and hard water ..but for RO ghe advise to use a bit of calimagic if i remember well
what EC/ppm do you use ?

i remember floranova i used this shit with success in coco, its thick and contains some salt crystalized
but it was with hard water
personnaly for RO water (100% demineralized water) i use dutch pro coco/hydro RO/SO
ro/so for reverse osmosis/soft water

OK. I do have RO on my well water. before mix PPM 24, After mixed PPM is about 2000ish. pH is good. possibly not mixing enough?
