i disagree, these plants require tons of calcium and even more magnesium, it would be very hard to cause a lockout from calcium. it is some strains that require extra calcium like my PK, anything less than full strength is no good. now you say lockout, but lock what out? what would higher amounts of cal/mag lockout? elevated amounts of phosphorous will lockout the calcium but i havent heard or read on it the other way around. 9 of 10 nutrient companies make nutes geared toward R/O water thus having a cal.mag supplement in your arsenal is always good, infact too much calcium and or magnesium wont lock anything out it would only become toxic and like i said it would take insane amounts of either to become toxic, high amounts of these 2 are more beneficial than not....in hydro people can lock out calcium if water PH is strictly kept under 6.0, some people are so strict that thier water never sees anything over 5.8 and thats not so good, calcium in hydro is best absorbed at ph's of 6.0-6.5 so this is something that needs to be taken into account. i said that phosphorous will lockout calcium, this usually occurs when running a high phosporous bloom booster in a hydro setup where there is no microbial activity, the higher P levels feed the mocrobial life, therefore this is good when running soil or organics or nutes that have been made with kelps and guanos and such, since there is nothing in the media or substrate or water to counteract the extra phosphorous, this will directly lockout calcium. now if you use fox farms beastie bloomz which is 0-50-30 at full strength with no type of microbes in your water and use this stuff for a long flower period you will get calcium lockout, but i dont know anyone who uses bloom boosters like that at full strength for long periods of time. i know fatman is good with water chemistry and i dont know if he would concur with me, but i got this info from a friend who has a PHD in botany on another forum. info like this is gold especially when running different growing types with certain nutrientssupplementing mag/cal is realy dependant on your nutes... If your nutes are designed for RO then it's not needed howerver most do anyways causing lockout and then they assume they have a deficiency. I use Aqua Flakes and you can really only use mag/cal at 1/2 strength or it will lockout... sorry about the spelling.. alarm going off! gotta go
