Hi guys. So I’m a novice. Started growing without the correct stuff but now got a good PH tester so back on track and got some new beautiful green leaves growing. With the lack of good PH, i have a lot of large yellow leaves. I also have a few leaves that were eaten last night, I took off 5 small caterpillar this morning, so will be checking every day. My plants are organic soil grown (using bio canna flores food right now) thankfully no other nasties so far. My boyfriend wants to take off all the large yellow leaves and I’m not sure this is the right thing to do. After doing some research , it looks like it could have been copper deficiency due to bad PH ? Anyway the question is, do the leaves stay or go please ?
