I water with 50% distilled and 50% rain OR 50% distilled and 50% tap. I have fed once with Grow Big and it happened right after. Might have rubbed nozzle on the underside of the leaves. I water every 2-3 days and water until drop of runoff appears in tray. How much runoff?

Hi mate, this is a PH issue. I would not use rain water for the simple fact it may contain pest eggs/larvae and impurities which will affect the PH. Try and keep her around 6-6.5 and maybe do a slurry test of your soil to check the ph your roots are sitting in. Water temperature is also something you need to watch. Between 67-72'F is optimum. Any lower and she will struggle to absorb nutrients. Any higher and the roots struggle to absorb oxygen. To lower the PH of your soil you can use a small amount of agricultural gypsum, dolomite lime to raise it.
I hope this helps, good luck and happy growing.

Looks just like when I would drip nutes on my lower leaves. Try to be more careful when watering with nutes. Once they get bigger and you defoliate the bottom leaves watering becomes easier. If you are in soil you shouldn't need any nutes for at least a few weeks depending on what you use. I've lately switched over to 3m out of Michigan. It is supposed to last the entire grow with only watering. I have found just my cities straight tap water which is around 200 ppm and pH of 7.6 has been perfectly fine for natural soil. Most soils are buffered for 6.2-6.8 pH. That combined with the microbial life will keep nutes flowing without adjusting water pH.

For runoff, 20% of what you put in is what the majority of people recommend. 🙂

Light burn, light burn due to humidifier water lights?What do you think caused this brown color on that leaf? I have 5 leaves like that, all the others are ok.
I believe it's due to pulverizing water and droplets acting as magnifiers for the light, causing small burns.
Also, since they are burnt, should I just cut them out?

Possible P Deficiency?Hey everyone, hope all is well. I noticed these past few days some dark spots appearing on some of my higher leaves. From what I’ve read it looks like it could be a Phosphorus deficiency. Any ideas? It’s on two out of three plants of the same strain. All same feeding schedule.

I have no idea what these brown spots are on my seedling?Brown/ rusty looking spots on seedling. Only thing I did was spray with a Epson salt and B52 foliar spray. The soil is deprived of magnesium so that’s why. I think I corrected by using cal mag. The sister plant is a few weeks ahead and showing recovery.

Brown spots on lowest leavesHallo Freunde!
Ich habe an den untersten Blättern meiner Pflanzen, Verfärbungen auf der Blattoberseite entdeckt. 😲
Ich vermute das etwas Überdüngung die Ursache ist. Week 3 Day 19
Wenn jemand die genaue Ursache und wie ich es behebe, erklären könnte?
Vielen Dank 😗
