My PH is 6.5 solid. I dont exactly have a ph meter but I use the drips. I check ph and EC before it goes into the pots and when it sits in the drain pan everyday on a day to day basis. I cut out the cal-mag to add in the sweet. Retarded idea now that I write it down but it sure sounded good for a while b/c cal mag is such a PPM hog. I just gave them all some tap water and a 10ml / gal shot of cal mag. I have epsom salt too but use it for cleaning my bongs I dont know how much to use for my plants , I grow in coco, its inert and pure so maybe there isnt any Mg without my feeding it on a regimen?sorry about mixing up the 1000s and 600s.. sometimes i switch parts of other grows in my head.. i appologize as it prolly wont be the last time it happens...
first im glad to hear you at least got a couple degrees of relief... can you possibly add a fresh air duct from the window into the grow tent to passively bring in fresh air?? it will help co2 levels.. the higher the temps the more co2 you need to add to suppliment because it gets used up faster.. butas long as you are moving air around well you should be ok.. it shouldnt affect growth to much... which brings me to the mg issue...
you might not have an mg deficiency at all... generally speaking there is enough mg in soil that we really dont need to add any during growth... that is not to say its doesnt happen.. but usually the problem lies else where...
low MG is usually related to a soil PH problem... soils that seem to lack mg are usually acidic... mg gets locked out as PH gets lower... so the problem could be just that your soil is too acidic and that the mg is getting locked out... do you know or have you checked the soil ph or run off ph?? it could be just as simple as raising the soil ph...
now this brings up whether to use epsom salt of dolomite lime... epsom salt will not actually raise the soils ph.. its a neutral salt and does little if anything for the soil ph... so if the soils ph is low, and that is whats causing the lock out, you should use dolomitic lime to raise it... this will make the mg available again and things will go back to normal.. if the soils PH is ok, which means it actually is an MG def, then adding epsom salt will replenish the mg... but make sure you check the soils ph before adding either dolomite lime or epsom salt.. if the problem is the ph, adding epsom salt will only further the problem... but if ph is ok and it is an MG def the lime will do nothing to help...
as far as the EC of the nutes... the 1.2 to 1.8 is the ideal range to have when you have everything total mixed in... so if its saying that you want an ec of 1.2 to 1.8, that is the finish ec after you have added everything in water for feeding..
I used to use Gen Hydro flora veg and bloom which was everything I needed in one, the canna coco nutes Im using dont have any of those goodies in there I suppose. Im going to do a better job at making all the nutes get into the mix. Hopefully it will straighten it out.
You have been a great help I really do appreciate it. Currently, I think that its not the lights or the heat as much as it is the Mg, well a combination of all of that surely so, but the leaves arent looking like the bleached leaves that are in the link I posted earlier, it looks a lot more like Mg, my leaves almost crack when I touch or bend some of them they curl into each other... idk it just seems right on spot. Its great to have someone to bounce ideas off of as well owe you big sir. what you think?
