Friend's leaf prblmen please look, Thx.

Hi all. Hope someone can help on this picture.

This is from a cheese strain, abour 4 weeks into flowering. 600wHPS, about 75f and 40%RH lights on. GO BOX full strength every watering. That's about it.

I told him maybe nute burn from nuting every time and not every other?????

Thanks Guys..

I usually try to reference this http://www.drugs-forum.com/growfaq/97.htm

I want to start off by saying you know way to much about your "friends" grow op lol
But to answer you it's definitely lookin like nute burn but you have what like 5 to 6 weeks max left so just ease up on em man and keep on keepin on later goodluck

He feeds everytime he waters? how often does he water.

It looks like overfeeding judging from the claw, upside down canoeing and crispyness. I've had this a few time but i catch it within 2 days when they start to canoe. A good flush will take care of it.

Thanks guys. I'll find out his watering schedule. I told him just ph'ed water or that +CaMg, for a few feedings. Yes full GO BOX nutrients every feeding. Previously myself and the local hydro shop though this was too much nut's, but his plants were/are looking well. The buds are nice and dense, smaller of course. Just this leaf problem. They are also droopy. I told him about lollipopping but told him not to do that yet until I talked to you smart folk as I am very new to this.

Thanks again.
