It's important to not rule out checking pH before doing anything, even in soil... "GigZ-16" on another forum summed up this a lot better than I could probably waffle you through it (Extracts Below) :-

"When growing in soil any fertilizer you use can cause an excess build up of salts when it decomposes in the soil. This almost always results in a more acidic soil which stunts the plant's growth and causes brown foliage. When using a Hydroponics set-up the nutrient solution can very easily cause a fluctuation in the growing reservoir. The water in rainy climates, such as the Pacific Northwest of North America, the UK, Netherlands and Northern Europe, is often acidic with a pH below 6. Lightly sandy soils with little clay and organic matter are quicker too become more acidic. Another common mistake is that a grower will mix his soil unevenly, leading to "hot spots" in the growing medium, so mix all ratios as well as you can.

What are signs of a PH fluctuation in my Cannabis plant?

A Cannabis plant can show signs of a pH flux in several ways. The leaves may begin to turn yellow or brown, dry up and/or shrivel on the sides into a straw like shape. Keep in mind however that other deficiencies and disorders may show the same signs of damage, so don't jump to conclusions until you do some testing and adjusting to your plants and their growing medium.

Some things to remember(I didn't write these ones)

1.Always test the pH of raw water and drainage water with a pH meter.

2.Raw water pH above 6.0 helps keep fertilizer mixes from becoming too
acidic.

3.The pH level is much more important in organic soil gardens than in chemical
hydroponic gardens. The pH dictates the environment of bacteria necessary to the uptake of organic nutrients."

This chart is im my view almost pointless as it barley adresses PH for one and pics are to few and of really poor qual!
i would advice anyone seeking an answer to their problems not to only go by this chart alone ---Use google---.

Hey, i need some help, this is my first time grow. it been growing good untill i noticed that a few of the bottom leaves started to get brown spots on the tips, very small but then as time went on it dried out the leaf and turned it yellow and crackly. The top portion of the plant seems healthy. is this nute burn? or something else. please lemme no so i can do something to fix it asap. Anything helps. Thanks

HOW DO I CURATE MY PLANTS?

what have u been feeding them ? the soil should have nutes so should just be ph'd water ! did u use stage 1 soil or seedling soil as they dont have as much nutes in (dif nutes for dif stages) how old is ur plant ? it does look like nute burn , new growth will be fresh lush green when u got the prob sorted but older growth will die off if damaged so dont panic. i hope this helps

peace out

How are you gonna say that sulfur deficiency starts with younger growth and the picture shows it starting with the bottom and working up? It amazes me how many nutrient deficiency guides there are on the internet and most of them contradict each other. I've seen the same identical pictures on different forums and websites claiming a different deficiency. I'm not an expert by no means; I'm actually a noob, but has anyone else noticed this?
