Thanks cannofbliss, so then why would adding magnesium fix the problem? I treated them with magnesium sulphate mixed with my tap water prior to switching to RO water. So from then on I just added additional Mg to the reservoir at the same amount as their initial treatment.
Further once I moved to RO and removed all the latent CaCl why did they require even more Mg? If it was lockout caused by tapwaters CaCl content wouldn't it have resolved after the move to RO water? Instead my plant's need for Mg seemed to climb in direct proportion to their size.
Interesting too I'm running clones of the originals and they are also showing the same need for more Mg in comparison to the Pre-98 Bubba Kush I have growing from seed next to them (the Bubbas are now just shy of 3 months old), that is fat and happy without any extra Mg. I am beginning to think some strains of cannabis are simply Mg hogs.
Thanks for your input,
Annie
ahhh... reservoir as in hydro??? cause i have never had Mg deficiency... ever... i guess thats another reason why i prefer soil
but nevertheless, there could have been other factors such as too high ppm and or especially pH issues... and by adding more Mg being alkaline, raised the pH up to where your plants needed it to be, or in some cases "certain strains" levels to where all of the nutrients were readily avail...
Or... due to that Mg, oddly enough, and as a consequence, since you are using hydro, probably pH'd below 6... as it should be
and anything below 6 on the pH, the amount of solubility of Mg drops off rapidly... so you had to adjust for "less solubility" by adding more of it to compensate...
but hey its all said and done with anyways, and you saved them, saw your journal and congrats on a completed grow btw...
and you got a decent harvest out of it, so hey thats whats important right... and glad to see that you made it through so well, cause surprisingly so many people for their first time, dont even make it through, especially in hydro so kudos and +rep to you
what i see now are much healthier plants...
arent you glad u switched to soil???
{EDIT} >>> had myself an artard moment when was too high to read her full journal where she stated "sunshine soiless mix... LOL i give myself the dunce cap award
...
i just happened to see your journal and plants and have to say that they are looking quite healthy compared to last grow...
just sayin in no offense to you, but it looks like you may have just some bad genetics...
perhaps its just the photos, but the genetics just dont look right if you ask me...
or either that they have the base "strains" like "bubba" or "aurora" and have indica in them but those are just some bad genetics...
here is a pic of someone elses grow as this should be a prime example of what is a VERY typical pheno and look of what that type of that especially aurora indica strain should look like...
even though you arent flowering yet, and even though he "says" "skunky pheno" dont pay attention to it cause i believe he is partially somewhat retarded lol...
but anyways compare your aurora and see the difference and bushyness of the plant and short node spacing...
here is another good typical example with less flowers...
there again you can see the difference, and your lighting should be adequate still to get this kind of result if you had the good genetics to go along with it and its not just about having a 1000 watt to produce this kind of bushiness, as it is mainly genetics...
anyways just tryin to help...
p.s. is that an inspector spacetime booth i see???
