How to Raise PH

[gezzy da snowman]

Hey i have 4 autoflowering lemon skunks and chemdogs all about 5.2 in soil. What should i start doing to raise the ph as it should probably be about 6.5 for soil. The leaves are starting to have brown spots after about 3 weeks

vinegar water = up
baking soda water = down

You got it backwards fella.

yea.. vinegar is acidic.. it lowers ph... baking soda does the raising....

how much it takes will vary....

you can also buy some PH UP and use it... a little goes a long way so use a little at a time and raise it slowly so you dont over shoot.. its cheap and can be bought at any hydro store..

i was wondering if you should add the ph up or down to plain water or just mix it with the normal nutrients

of course water first then into ur nute/water as long as ur ph is cool at the end wat ever way is fine

Check the PH before and after adding nutes.
If I add humic or fulvic acid at 4ml per litre the PH goes from 7.1 to 5.9.
That's why I check both times, some nutes contain these.

I been using natural up by earth juice and it seems to be working fine. If you do go the baking soda route watch for salt buildup. Make sure you flush cause it does have salt in it

Try adding fine dolomite lime to your soil. It helps buffer it against abrupt pH changes.
