Hey Guys. My problem is the yellow spots on my leaves. I have no idea what it is. :shock: First time grower btw.
Room temp is 74F rez temp is 72F.
I'm using Advanced Nutrients. Grow/micro/bloom in recommended amounts.
She is OG Kush 5 weeks from seed. Toped a week ago and ready for flowering.

72 for res temp is a bit high, should be under 70 at all times. Mine stay between 66 and 69 and only once reached 70, you might want to try and either get more air flowing around your buckets or covering them like me with the white/black backed plastic to avoid the black pulling heat into the res, its almost like a bib on my buckets lol.

My plants are about 3 weeks old now and I had the same thing appear, in my case it was nute burn. I put in a recommended dose as well for seedling, when really i should have done 1/2 to 1/3 of the recommendations. I did a res flush and change, then topped up with 1/3 nute recommendation and the spots stopped appearing, the old leaves are damaged and cannot come back so i cut them off so the plants stop trying to repair them.

Problem with nutes and recommendations in my experiance is every strain is different. i have 2 automara II and one Senis Star, the automara's took the recommended nutes with no issue but the seni got these same spots.

By no means am I an expert but my plant showed the exact same thing and the flush with a reduction in nutes fixed it.

I think going forward for me its always best to start low with them and very slowly move up 100ppm or less at a time with each res change

Other then the spots your girls look great! I hope this helps you and your girls!

Thanks for the input :) Trying to come up with a way to cool the rez...Was thinking about frozen water bottles in the rez.

I use AN Ph perfect 3 part, too. I found that you don't need to run it at full strength. Presently I'm using it at 2/3rd strenght, and the plants are loving it.

And just in case you didn't know... when making the nutes, add the micro first, then grow, them bloom. It has something to do with the way the solutions balance the Ph.

I did not know that. TY;-) Does it still keep the ph balance @ 2/3 strength?

Correction to my last post.

At 2/3rds strength, Ph drifted and I had to correct it.
At 75% the Ph perfect worked.

nute splash or windburn its hard to say for sure
no pattern to the marks so thats the likeliest cause

plants look good though

in my experience the pH Perfect tech works fine at 2/3 strength but it depends a bit on your water how well/long it will keep it set perfect
with RO water i have to change out the res with fresh nutes long before the pH starts to drift at any strength

ymmv

that is not ph issue.
