how to lower PH

[demistify]

good morning!

 

outdoor soil grow, mostly organic. sativa. applied too much chook poo at onset of flowering. growth 'siezed up'.

 

subsequently have flushed well. sprayed kelp on foliage. growth began again but is wacko (see pics).

 

checked PH. need to lower PH. understand from research these forums that epsom salts, vinegar and phosphoric acid will do the job. HOWEVER no dilution/application rates seem to be available. can anyone assist? (don't send me to bunnings! have phosphoric acid available.)

 

is REVEREND in the house? saw some of yr old posts on this issue, Rev. Radic, what's the organic viewpoint here? assist pls?

Aluminium sulphate will do the job (just dont get it on the leaves)

 

I had this issue with my first grow in soil, you can get the Sulphate in Bunnings in the garden section, i've even seen it in Big W.

 

Follow the labeled directions and you should be sweet

 

 

 

Also i'd like to know what causes the three pronged leaves as i've got a clone atm who is only growing them but the seedlings are showing the full leaf.

When a plant is stressed it will often revert the leaves back to their starting leaf shape which is 3 'prong', then it will regain another 2 leaves for every new leaf formed until it is back to normal - such as 7 or 9 leaf.

 

If you take clones you will understand.
