Hey, im quite concerned as it is my first grow. I have a few plants in a small tent under 2 55W cobs. This particular auto is in week 8. I know my yield will be quite low. The plant has started turning brown in the upper leaves. I thought it was nute burn but after flushing it just got worse. I think its underfeed so im waiting on the soil to dry. Whats your opinion?

Temp, humidity, ph, light distance and calmag?

Light distance is around 20cm, temps 20-27. I dont test ph every water since I use biobizz ferts and soil and it says its not necessary, anyways ive used strips and its always around 6. Rh is 50%.

If it's not lights or temps, it could be you're over watering or your ph is whacked. I don't use nutes that don't "require" ph, but I've seen lots of problems with them.

Either way, looks like your root zone is unhappy. Pick your pots up. Water when light. Check your ph for a while just to be sure.

Your girl appears short on Ca. I would revisit your pH; check it and check it often, regardless of what your nutrient manufacturer tells you. Remember she's an auto so tread lightly with your changes; you can't afford to set them back any further than necessary. Good luck.
