Why are my leaves turning

What soil are you using, are you fertilizing and how much, what is your soil or water pH, what lights are you using and far away are they. Please give us more details

@Vaughndutch. Welcome to our world of grow at ILGM

I’m going to give you a Support Ticket. Please fill it out.
You have one of two things.

ILGM Support Ticket:

What is the strain and type(unknown bag seed, strain name, regular seeds, feminized seeds, auto-flower, etc)?

Indoor or Outdoor? If outdoor, planted

in ground or in a container?

Size of space (max height and area, length/width)?

Soil or Hydro? Type of Medium used? System type?

pH? Of the soil or medium (root zone/reservoir/run-off) and of the water and/or nutrient mix that is fed to the plant?

Type and strength of nutrients used? NPK? EC/TDS/PPM levels? Of what you feed it as well as what is in the water by itself and in the soil/medium (run-off), or reservoir.

Temperature? Day vs. night temp or highest and lowest temps? Root zone temps?

Humidity %? Day vs. night

@Vaughndutch ,

Am I reading this wright. You are feeding only BLOOM !
If you are than that’s your problem.

Nitrogen Deficiency

Nitrogen (N) Mobile Element and Macro Element

Benefit: Nitrogen plays a very big role in your plants; this one element is directly responsible for production of chlorophyll, photosynthesis, Amino Acids, which are the building block of Proteins. The myriad of enzymes which help the plants growth in leaves stems and the how well the vigor of your plants is.

Nitrogen is the biggest mobile element meaning it can travel anywhere on the plant.
Usually the def will start on the lower to middle part of the plant, and then will usually happen to older leaves first. Then the deficiency will work its way up the plant. Your plant can be green on top, then yellowing on the lower leaves when the deficiency is starting out. Yield will be greatly reduced without good amounts of nitrogen in your plants. Sometimes in bad cases the leaves will turn a purplish color along with the yellowing.

Solution to fixing a Nitrogen deficiency

Avoid excessive ammonium nitrogen, which can interfere with other nutrients. Too much N delays flowering. Plants should be allowed to become N-deficient late in flowering for best flavor.
A goof solid N-P-K ratio will fix any nitrogen deficiency. Any chemical or organic fertilizers that have Nitrogen in them will fix a nitrogen deficiency., Peters all purpose plant food 20-20-20 is good, Miracle grow All purpose plant food, Miracle grow Tomato plant food, (Only mixing at ½ strength when using chemical nutrients, or it will cause nutrient burn!) as well and blood meal! If you need to give your plants a quick solution to nitrogen and you want to use blood meal, I suggest making it into a tea for faster use, where blood meal is slow acting, but when made into a tea it works quicker! Other sources of nitrogen are dried blood, Cotton seed meal which is slow acting, Insect eating bat guano which is fast acting. Bone meal which is a gradual absorption when not made into a tea.( also excellent source of phosphorus). Fish Meal Or Fish Emulsion is a good source of nitrogen and is medium acting. Worm castings, which is gradual absorption. Seabird guano, All purpose Millennia Seabird guano, Orginal Seabird guano All Purpose, Crabshell ,which is slow absorption. Fox Farm Grow Big, which is fast acting. ( can bring down your ph as well)
Here are a list of things that help fix a Nitrogen Deficiency:

Really need to find out what your pH is as well.

I didn’t understand, until this forum, how important pH really is. Even giving your plant all the nutrients it needs, they are only absorbed in the proper range. Too high/low and you could lock out what you need.

I found out that most of my issues were pH related.

Welcome and everyone that is able to help will enjoy doing so to get you to a successful harvest!


That’s how I learn most of the things I know now xx just read every post on everything that has ever been posted lol
