This is my second grow and within the last day I have had some brown spots show up on two of my plants. Looking through the some of the plant problem posts it appears to maybe be a PH issue? But the strange thing is no matter the problem it's only showing up on two plants and they are all under the exact same conditions?? Please help before it gets worst! Pics attached - thanks guys!

Details: 8 plants all Master Kush

Age: 4 plants in the middle 2 weeks from seed, 4 outter plants 3 weeks from seed - started counting when the sprout broke the surface give or take a day.

Temp: 75 night/80-85 day depending on outside temp, but 85 is about the highest I have seen.

Soil: FF seed starter, going to 3 Gallon FF potting soil this weekend

PH: water 6.0-6.5 - just checked runoff @6.7

Watering: all have 1GPH drippers that run 2 min per day right now off a 150GPH pump.

Fert: Only a small dosage (5drops) of superthrive in my 5 gallon res.

Light: 600MH air cooled 10" above.

I think it's nothing to worry about. It's probably an anomaly; a nute splash, or 1 plant that isn't as tolerant of the nutes.

Great looking plants by the way

it appears to be a nute lock, cant be a splash as you are drip irrigating. As all your others are fine then just ride with it. You may want to repot into larger ones soon. GLuck

Thanks - I just gave them a light flush with 6.0 fresh water. Also upped the drip to 4min per day as they were drier than I thought. This weekend they are going into 3 gallon pots and I will probably add more drippers - 2 per pot.
