Leaves have brown spots and wilting

lt1jeromestarted grow question 4 years ago
What would give my leaves these brown spots and look wilted? She is on day 20, this started a few days ago so I raised my lamp from 14" to 22" and no change. I have only been giving 7.0 PH water. Does it look like i need to do any trimming? Not sure if its a light or water issue.

She is in a 2 gallon pot with coco coir (I bought one of the kits from A pot for a pot) I have only given tap water that I PH down to 7 (which now i know is high), I do have general hydroponics nutrients but haven't started them yet I use a mars hydro 1000 light, everything was looking good when I had it set at 50% and 15" from the plant, then i tried it at 75% and 22". I water pretty much everyday, when the first inch is lightly damp (I could probably get away with watering alittle less and see what happens) I'll have to look up on how to check PPM

Ph of 7 is too high bro. Get a ph pen, some calibration fluid and ph down.

don't need to trim - unless you want to do so. As long as internode space isn't long or stacked on top of each other, your light is fine too. Looks like a deficiency, but need more info. e.g. if it is soil and you've fertilized from day 1, it's more likely lockout, so you'll need to consider recent behaviour. do you water only after top 1" dries? do you always get 20% runoff or more? These things maintain equillibrium in the soil so it doens't build up too much and you don't have a dry pocket of substrate or some region of your substrate with inconsistnet nutrient levels that can becomes real problems in short order. Also, 7 is probably a bit higher. Get it to 6.5-6.8 for soil.. at least slightly acidic.. don't have to be as precise about it with soil. I'd try that along with any changes to watering habits i mention above and see how it reacts. Also, start calculating the PPMs of the feed you put in -- this will help diagnose problems immensely! Nute ppm calculators exist on the web.. you can also download my spreadsheet linked in my GD profile comment senction. It may or may not work for liquid nutes, so verify with an online calculater with at least one of your guaranteed labels, if you choose to go that route... belive it handles specific gravity correctly, but i do not havea a degree in chemistry.

Hey there! I'd love to help you out, but I have lots of questions my man: What type of lights are you using? How often are you watering? Filtered or Tap? Are you using any pH down? Feed schedule?
