Hello everyoneb! Running into an issue with kne of my strains. Yellow/rusts spots are happening and moving up the plant. This is in flower around 26 days. Buds are forming nice so it’s surprising. I use house and garden nutes in pro mix. Drain to waste. I feed once a day around 2 ec. Waste water comes out around the same. i use co2 also. Gavita lights, de at 1000w. Been running this strain for a while and yhis hasn’t happened. I did add more light and since the buds are forming nice i am wondering if this a deficiency of some sort since this didn’t happen in my last harvest. No signs of bugs or disease, unlesss this is a disease. Temps stay around 80F and rh is 50% consistently

I would like to see what people say to this. It has happened to me a couple times now but always seems to iron itself out before it gets too bad. Once I start to use tap water without ph down it clears up.

Well it has to be immobile sonce its starting halfway in the plant. I was waiting for the all the calmag comments. It might be a calcium deficiency or some lack in micros

Yeah its what I think. Ive also used cal mag and plants bounce back. Found out using my high tap 7.8 water is cheaper and has plenty of magnesium. So Far so good with just tap water un ph'd in foxfarm ocean forest top dressed three times

Tips look slightly over fed. Try bringing down the ppm's. The darkness in the leaves indicates too much nitrogen. Could be cal-mag, but there would be some brown in the yellowing that far along.

You’re right. I have some tip burn. I use an amino product i. The beginning of flower that is higehr in nitrogen
 
Can you post some pictures and info? Soil type, feeding regime and brand? Are you phing?


here’s a thread I made earlier with a little more info, this was the first thread I ran into that looks like the same issue I’m having.

Okay so, I took a look at the pictures without even reading anything and immediately see dark green waxy leaves which is a sign of nitrogen toxicity. Do you own a ph and ppm meter?

okay, so I just read you are using Gaia green bloom, do not dose cal mag, Gaia 284 is 16% calcium. Calcium is not your problem. The problem you see is to much nutrients, how much are you top dressing, how often and what soil are you in?? How long did you wait until the first top dress?

I only top fed once a month ago based on what the bloom container said. It’s in build 3.0 soil 5 gallon pot. Just been giving tap water left to sitting overnight with fish shit. Every other watering I use recharge. My tap is 120ppm. Since a month ago I haven’t used recharge or top It anymore. Just water. I did have humidity issues up until 2-3 weeks ago. Kept creeping to 80-90% but that’s under control now. PH to 6.5

Okay, I want to say that you will not see benefits this grow, you are to far along to see any changes at this point, with that said I would stop the fish shit and recharge and water only.
Can you water to slight runoff and check the ph and ppm of the soil?

I use Gaia, build a soil, tm7 and homemade living soil and these are my results, I can say they both make a great product. IMG_1936.jpegIMG_1934.jpegIMG_1911.jpegIMG_1665.jpegIMG_1198.jpeg
