I thought i read some where online that calcium deficiency could cause the disease Rust?
Is this possibly and more prone on cannabis?
Back when my 4 girls where about 3 weeks old i had a calcium def. typical copper spotting and such. it got slightly bad fast. like within 24hrs. Ran a flush on the plant with phd water and then a feeding of calmag and it seemed to stop once i added the calmag to the water. Im dealing with it again now 3 weeks into flowering but i have been feeding botanicare bloom and calmag every watering per instructions. growth is great along with bud growth but now im getting the spotting on new top growth again. Its gotten fairly bad once again within 24hrs ( could do anything due to plants where to moist).
I finally ran a flush on all 4 yesterday with phd distilled w/ calmag 5ml. I think i got it to stop as theres no real new copper colored spotting just darkening and dying now. 2 of my plants fans started turning yellow,copper, and dying off pretty bad within 36hrs. I pulled those.
What im curious is, am i truely battling calcium or now rusting? Back when i was in veg and had this issue, it started on 1 plant. Then by the next day it was onto the next plant, Then the following day onto my 3rd plant. Only 1 plant of the 4 didnt get it until about 2 weeks later ( this plant is ind other 3 are sat. random bagseed unknown strains ) Or is it just possible i got salt build up and it locked out my cal? No signs of Mg problems on the leaves. forgot to check runoff ppms before i dumped it.
Now once again it started at 1 plant, then the next, then the next, and now the 4th is getting it. I think i caught the 4th in reasonable time. I chalked it up the first time to calcium deff and maybe that all of them just happened to show it at the same time(ish) as i wasnt supplementing any calcium back then in my waterings, but i have been every watering since then, 4 weeks later.
random bag seed - 4 girls
FFOF soil - 2x3gal 2x1.5gal
Botanicare bloom 20ml calmag 5ml - fed every watering per botanicare instructions. No signs of nute burn or any other problem so i kept with the every watering feed.
400whp hps - 3x3x6 tent w/ scrubber and inline
temps 72 lights on - 66 lights off hum 35%
I almost think i need to be adding more then 20ml and 5ml at this point in their stage. they are taking the feedings really well but the bottles call for 27ml and 5ml now on week 3-6, but my nute chart from their site which i filled in pot size and such tells me to stay at 20ml. ending ppms are around 950-1050, but i feel like i should be higher now.
Heres a few pics of the spotting. Couldnt get any of the real bad leaves since the lights just went out in the basement.
Any help, links, info would be great.
Thanks in advance!
