Also the soil is westlands multi purpose compost with added John innes. From what i read this has dolomite included in the mix and has a start PH of around 6.




that's some pretty damn acidic soil.  Did you buffer it all?  You generally want soil Ph to be around 6.8.

:S nope, just planted the seed and let it grow.

I will say im pretty new at this. Knocked out a couple of lowryder 2's in the same soil though and they went from seed to harvest without any problems. Thats why im a bit baffled at why this has started with problems so early.

I'm gonna make sure i get a PH tester kit and some epsom salts today. I'll test the PH first and if its stable i'll see what effect the salts have.

Right i checked the PH today. Even though the soil was 6 the water is around 8 so it seems to be settling at about 7.

From what i've read 6 - 7.5 is acceptable with optimal around 6.6 (?)

I've got some Epsom salts now so hopefully this will sort out my problems!

Thank you everyone for your help. Just another reason why i love the growery!

6 is really, really pushing it.  I wouldn't want my soil going under 6.5.

Also, whatever you do right now, do NOT feed your plants any more Mg.  Here's why:

Soil

Magnesium gets locked out of soil growing at ph levels of 2.0-6.4
Magnesium is absorbed best in soil at a ph level of 6.5-9.1 . (Wouldn’t recommend having a ph of over 7.0 in soil) anything out of the ranges listed will contribute to a Magnesium deficiency.

If your problem is being caused by your Ph, you need to fix your Ph FIRST before doing anything else.  If Mg is being locked out feeding it more will not do anything but cause more issues.

I just this second read that exact same info on this board somewhere. lol!

I haven't actually fed it any Mg as of yet.

I think what i wrote was misinterpreted. The soil was Ph6 when purchased. After doing a test of the soil today it showed as being Ph7. So I'm at neutral PH at the moment.

Hence why i got the epsom salts, cuz the PH seemed at a reasonable level.
