Brown stains on leaves edges

blasterw32started grow question 5y ago

The top leaves on my GG#4 started to get brown on the edges. Initially I thought it was light burn, but the stains kept progressing after I readjusted the light distance. Is it a nut burn?

I don't think they're burned. Leaves burned by light behave differently. They twist and look dry. Your leaves look good, try to raise the PH a little to 6.5 if you are watering with a smaller value, or check the EC and play with the dosage of nutrients.

Browning spots after H202 rinse.Hey guys! My first dwc and I’m having an issue. So after about a week my water was cloudy. I rinsed and washed the bucket, fixed the area where light was getting in. Then I rinsed my cube and plant with H202 3%, 1/3 to 2/3 water. Changed out nutes but now look like this. ?

Brown Spots on Leaves I've got some brown spots showing up on the Wedding Cake leaves, first thought it may be mold but it doesn't rub off and I sprayed both plants with neem oil about a week ago just in case. Could be CalMag deficient? I use RO water with about 150-200ppms in 3 liters once a day.

Response to Weezy Hi @Weezy90, the left ones are indeed the Purple Punch. So straight water now for the last week/2 weeks? The one on the right is the NL and is 2 weeks behind the PP's so I'll lower the nutes on that one. Thanks

Brown leaves - what am I doing wrong, folks?They look yellow in the photo, under 250W of blue light, but they are brown. This starts at the tips of the large lower leaves and spreads quickly to the whole leaf. Also modest edge curl. What am I doing wrong here, folks?

Moin, bei meiner Größen Pflanze fangen die Blätter an von außen gelb zu werden und braune Punkte zu bekommen. Ist das ein Zeichen von einer überdüngerung? Alle anderen Pflanzen haben dies nicht. Oder zu wenig?

Brown yellow leaves?Can anyone help me? I had this issue with my last early Miss and thought it was a cal mag deficiency. I tried to adjust it last time during flower but it didn’t help. I really only notice it on one of them so far but I would like to fix the problem sooner than later.

Flushing don't seem to solve my lockout It's been 6 days since I noticed the problem. first thought it was a deficiency but really is a lockout. I flushed 2 days ago but she keeps getting worse. Am I being impatient? I flushed with tap water pH 6-7 until the runoff was in the same range and haven't fed her for 4 day.
