Help needed identifying issues with my plants.

HoriCannaGrow · Nov 18, 2025

So my plants are in week two of veg and I watered about three days ago then started noticing brown spots on my leafs on two plants. These four plants are the same strain and have been fed with the same nutrients and pH level. (EC 1.4 6.1PH) I tested the run-off straight after water and all was fine. Tested again today readings were between 1.6 and 2.4. Any help to recover these plants will be much appreciated!

You might have some nutrient issues going on there. I would back off what you are feeding. I usually go with a 1/3 or 1/2 of what the manufacturer recommends.

Yeah, stop feeding and just water. If you see an improvement, you can get back to feeding. Just do it in smaller dozes

what soil you using?
what size bags?
how much water you give each plant?
how often do you give them water?
what light you got and how close to top of plants and what % setting do you have it at?
this could be a watering issue and light issue,.

also have you noticed any itty bitty tiny flies (gnats) around the soil surface?
