Yeah PH is hard, don't buy a Amazon PH own they don't work worth a crap.
I know I can't use my tap water as it's around 8.5 so it is way to high I have to use spring water.
The mulch I would say just get more nitrogen into the soil, and maybe a thinner layer of mulch
lol don't worry, I don't buy on amazon...I'm from Argentina.
And Yeah PH is hard. Your tap water is really bad man!
I know that there are test strips that are sold in aquariums but I don't know how effective they are.
I understood about the mulch,
I'll try a thinner layer then. You have a good eye, as the mulch I put on them is quite thick.
Thanks man!
