This started happening a day or two ago, it was just a few brown spots, and some of the lower leaves were turning brown, figured it was a Cal-Mag issue. I've been giving her Cal-Mag as well as other nutes. Any help would be greatly appreciated! Info: Mars Hydro 100Watt x2 Been watering at PH between 6-7, mostly around 6.5 Runoff PH around 6.4 3 gallon cloth pot, FFOF soil with 30% perlite. Watering every other day or so, she's very thirsty. Pot gets dry and light after 30+ hours or so. General Hydroponics 3 part nutes. Buds seem to be doing good, but fan leaves are browning, my only guess would be root rot? IDK though.
I did post the runoff PH in my original post. But, when I watered and fed last it was 6.4. A very healthy PH from my understanding.
Oh for sure, I have 2 successful grows under my belt. PPFD and DLI aren't an issue. I'm getting around 750-800 PPFD at canopy level. And lights are at the max height in my tent. And plants get around 41 DLI a day. Guess I'm just going to chalk it up as normal part of flowering. The buds are still good and growing, can see them getting fatter by the day. It's a 63 day harvest strain, and I'm like 40 days in.
