Close to harvest? Not even close. That probably has 6 weeks to go.

Curled serrated edges are usually due to light stress or heat stress. How close are the lights and what are the temps?

Yeh I thought it might be the light so I’ve lifted it , temps have been 25 to 30 deg , 600 watt hps

6 weeks !?, ok cheers , the buds will be huge lol I’ll be looking for 20-30% amber anyway

Definitely. Just make sure they have good air circulation because those fatties will be prone to bud rot.

They could use a little more magnesium too, looks like...Epsom salt in the water is the cheapest way. like 1/2 teaspoon per gallon, probably til harvest.

Looking good though!!
