hi, i am 4 weeks into flowering and ny ph level is reading 4.5 too acidic,whats the most effective way to raise this level? i am growing in a mixture of soil and perlite using miricle grow 15 30 15 every 4th watering, next time i will have built up nutrients to 3/4 strength.
I have some bicarbonate of soda but i understand this is not the most efficient :
dolomite lime(available at any garden shop)of course you know a soil "ph"of 6.2-6.5 for soil,will give you a safe buffer zone up or down...sweet dreams....bonbon :eek:
thanks, does lime dissolve in water or will i need to try and fork it in? :
you might have to flush some of the fert out(that itself may raise it)or after you check it,and it's still a little low,wait for the medium to drain,and water with the lime checking the ph every day till you get you're target range,it will take a few days to do this,but it's the safe way,better yet,follow the directions for a quick fix....bonbon
is your plant showing any signs of the low ph ??Quote:

I gave a small feed of epsom salts 2 waterings ago as i think it may be a magnesum deffiancy with the speckling on the leaves, it dont seem to be getting any worse
thanks for your help
sounds like you've caught it in time,dont forget magnesium is alkaline too, so it will raise it(ph) some also,it will come around soon....bonbon :eek:
hey bonbon thanks for help, didnt know epsom salts was alkiline, maybe dats why my ph levels are a little better than before. Anyways man things are looking good.
thanx :)
