  1. Hi UK420, I'm hoping someone might be to offer some advice on the following. Since growing i've had MG def Usually showing on Autos on the 4 th/5th week and in photos around the same time. with the rapid loss of leaves to follow. My first counter to the problem was to add Epsom salts at Week 3 -5 this made some improvement but was still a big issue. I then added Cal / MG in the form of Equilibrium , this actually made it worse. My next step was to test the PPM of my Tap water which came out around between 250-290 Looked online at my water suppliers Information and stated it was a Hard water area. My conclusion was that it was possible i was suffering CAL toxicity and in turn getting locked out of MG. I Bought some TNT Bactorr in the hope the Bennies would chealate the excess in the water I also bought some RO Water in the hope of starting with a clean sheet would be easier on my next grow ,but soon discovered that RO water needs to buffered ideally with tap water. (Haven't used the RO Water yet) I Also changed Nutrients towards the end of my last grow From Plant magic Oldtimers Bloom (the newer thin one ) over to Bio canna flores In the hope that using a nutrient with lower cal might help the ratios of cal to mg I also realized that i probably over watering as personal observation on my last grow. and that photo period plants i did last grow did suffer from mg def but i had time to rectify with Epsom salts ,where as with the autos they never seem to recover fully. In that time i was looking for more alternatives , and was looking for hard water nutrients, well to my knowledge there aren't any hard water based organic nutrients ? I seen the positive feed back given to Growers Ark on here and had look , seen they do water tests also noticed its salts based and therefor not organic which to be honest put me off a tad,but without any current alternatives i decided to buy the Soil starter kit but not before requesting the Water test , GA Who were extremely Helpful and i see why they have a good reputation on here. Completed the water test and sent the following info. " So basically not to much MG in water and by using GA Hard water nutrients i should be OK. but ideally i want to keep organic ,although some of my next grow will be done with GA soil kit And with Bottled organic nutrients i guess i should be looking for a feed with high MG Or some sort of amendment to the soil? or of coarse i could just add Epsom salts through the entire grow adding to the water but I'm unsure how much i should be adding ? Given the info provided above would anyone be able to give advice on roughly how much i should add and when ? when it comes to adding MG, I Guess this would also depend on what nutrient i used? at the moment i have the complete PM range Plagrons alga grow and bloom and Fishmix and Bio Flores when it comes to bottled organic nutrients. As mentioned above i have 100 ltrs of RO water i was planning to use this on my next grow in the hope of eliminating what i thought at the time was high CAL levels now knowing its more to do with low MG , Will adding Tap water as a buffer still be a good idea ? i fear i would still have to add MG to the water because its not going to be in the Ro water and its not in the tap ? Just about to start another grow and if its not obvious yet i've completely confused myself before i've even started. To add to the confusion i also wanted to have a stab at No till style to see if that could offer a better, easier solution so bought 2x 15ltr Air pots and some organic soil Plagrons Royal mix along with the Dry amendment Supermix some worm casts , air pump, compost tea,etc its not real NO TILL in the sense i havnt sourced the individual ingredients ,to me its more about testing the style of growing and seeing if it could potentially be easier to combat my issue. and doing a small run actually works out cheaper to buy the ready made Dry amendments ,if i see it has potential i of coarse would look to Either Buying better Dry amendments Like Botanicare Growilla Or one of the Soil recipes on here and wanted to use the RO water for this grow . should i just bubble some tap water off instead ?given its not going to have much MG as stated above, i've since bought a large Britta water filter Would using this be better? Apologies for length of topic i thought it was important to tell you as much as i could in the hope of getting a better solution. hopefully i've just fried my mind writing this and not yours Thanks for reading Barry
