Im currently in my last 4 weeks of flower and my plants are fading bad. This is due to a ph probem, theyre stuck at around 7.4-7.8. Ive bought some aluminum sulfate as an attempt to quickly lower the ph. I know this isnt a good long term fix, however I want to quickly lower the ph and it only needs to last until harvest in 4 weeks. My concern is ill kill ther plant through aluminum toxicity or kill the roots. Does anyone have any info on this? I really need to lower the ph quickly as its massively affecting my harvest.


Id also like to add that i know what caused the ph problem and its been fixed so it shouldnt causes issues in other runs I do.

Get a ph pen and some ph down. Add the ph down to your water till you get to 6 for hydro or 6.5 for soil. What nutes and medium do you use.

I use organic amendments, I already water it at that and it doeasnt affect it due to the amendments in the soil.

How far from harvest and when last did you feed. I rather a well fed plant than a starving one in organics. No flush necessary.
