Growing haze clones - approximately 8 weeks old - Currently just started flower a day ago have got some pics attached my leafs are getting brown tips , on the old growth and new growth! Growing in coco , 600w led, high 40- mid 50 humidity , 25-28 degrees Celsius with lights on, feeding using the canna range, canna a and b - 3ml of each per 10l, 1ml calmag & 6ml Rhizotonic. The pictures below as you can see there are brown tips everywhere, not massive brown tips but they are there! Was wondering if anyone could assist me!

I agree with pepperhead looks like slight nute burn. but really hard to tell with the poor quality pictures in the blurple lights

yeah I understandand because it’s in flowering Ican’t really get a pic with natural light ! But it’s literally a lot of brown tips, all around the plant and on new growth

Generally, I think Sativas can be very sensitive to nutes, and more easily burnt by nutes than Indicas.
Nute burn, use less nutes.
Start of nute burn, maybe a quick flush is in order?

I have changed my feeding and am using less nutes 2.5ml of a and b now, as opposed to 3ml of each ,hopefully it helps! Thanks guys , i am on my second day of 12/12 btw

@hazeluv69 i have a Bandaid Haze #7 and she doesn’t like nutrients at all. Right now my ppm is 199 with Megacrop nutrients. Any higher than that and she shows nutrient burn.
I'm I just ran Amazing Haze, and it was the same. I'm now doing Grinspoon, and same same. Generally Sativas are nute sensitive in grow and early bloom. You can usually hit them harder in mid-late bloom.
