Hi - This is my first grow and could use some help. Two plants, both Green Crack, leaves have started to brown on both. Today is day 41. Everything was going fine until about a week ago when I started adding nutrients. I used FF Trio at 1/2 strength on day 35, and now this. The leaves could have been browning before that, but I did not notice. From other posts I find that it might be a PH issue? I use a soil tester and it does say the soil PH is high, but I’m 1) Not sure how to fix that and 2) What to do about the damage already done. I planted them both in FFOF. Thanks for any help. Below are some pics…

Welcome to the forum! Are you using calmag?

Thank you! I am not using Calmag. I have not used anything other than the FF nutes that I used once.
Welcome to the community Growmie. What was your input and run off PH and PPMs/EC?

well I had never tested runoff until just now. I put water in at 6.08 PH and 103 PPM and it came out at 5.6 and 3361. Did the FF soil already have enough and I overfed them by adding more nutrients?

Soil grows should be Ph@ 6.5 going in, are you using one of those probes with 2 legs? If so there not very reliable. FFOF should be good for 5-6 weeks. like @Borderryan22 said give them some Cal-Mag FF soil doesn’t much Cal-Mag in it.
