Im about 4 weeks into flower. and all throughout my girls life shes been happy and healthy, until the last few days.
This is a soil grow using about 60/40 MG potting mix and sphagnum peat, plus a good amount of perlite thrown in for drainage.
A few days ago i noticed some bottom leaves getting a little yellow, but i had just fed some 15-30-15 so i decided to wait it out thinking shed be happy once she got some nutes. today i looked back and i saw some spots of necrosis on some leaves, and over the next few hours i watched them progress and took pictures. I used pool test strips to PH my soil, but theyre horribly hard to read. i over watered with 7ph distilled water and tested the runoff. the runoff came out around 6 so im guessing that means the soil is way too acidic. im going to start PH testing the nutes i feed and feeding it at around 6.5-7 by adding baking soda as necessary. im going to get a more accurate ph meter as well
In the pics you can see some necrosis and yellowing veins which leads me to believe it might be a potassium dificiency. what can i add to boost potassium? should i get a fertilizer with more K such as a 2-7-7?
Heres the pics of the light leaves, followed by the progression of necrosis over about 5 hours, followed by some nug porn because i want to show off my first grow
