All my plants have suffered the same thing and it acts fast. the leaves are progressively getting yellower and drier and droopy. I'm new to this and have not been adding any nutes or anything, just water and light. If you could help please do, I'm down to my last plant.
Look into the effects of "overwatering", "compacted soil", and/or "soil aeration". If temp's and humidity are within acceptable parameters, I bet your trouble lies with one of the aforementioned soil conditions. What soil are you using?
Time to transplant. That soil looks really compacted, roots like light and fluffy soil so they can get oxygen. Sent from my iPhone using Grasscity Forum
Wow. Can weed plants get blight? My phone res sucks balls (it was free, meh), but from what I can make out ......if that were say a tomato plant Id guess early blight, lol. Bit buzzed, too.
