Decided to change my light to the Mars Hydro TS3000. It's seems to be a great light. The plants are happy with it. It's just raised the temp in the tent by quite a bit so I've had to turn on the second oscillating fan and speed up the air extraction. First of two tops done.
One of Purple Afghan Kush are showing what looks like a bit of a nutrient issue. Not too sure what it is though. It's showing yellow between the veins on the leaves. Any advice would be appreciated!
