Marijuana Plant Problem Solver
One of the best ways to avoid developing a nutrient problem is:
- Creating a strict marijuana plant fertilizer feeding schedule.
- Developing a fertilizer recipe.
- Tracking progress via a grow journal.
When a problem begins to show itself, an experienced marijuana grower will check their journal to determine how the problem possibly began. The slightest change in marijuana fertilizers can either be a rewarding experience or disaster. Too much of one fertilizer may harm the marijuana plant. Not enough fertilizers and the marijuana plant won't reach its full potential.
Pay close attention when using nutrients. Purchase proper measuring tools especially a pH and PPM meter. The pH of water after adding any nutrients should be around 5.9-6.5 (in rockwool, 5.5-6.1). A guideline for PPM levels when adding fertilizers is as follows: seedlings = 50-150 ppm; unrootedclones = 100-350 ppm; small plants = 400-800 ppm; large plants = 900-1800 ppm;
Always check the pH and PPM after adding marijuana fertilizers!
When feeding your marijuana plants nutrients for the first time, start slowly. With few fertilizers. If you're unfamiliar with a fertilizer follow the directions carefully. Less is more.
Many brands of marijuana fertilizers come in two parts an A and B. Follow the directions carefully. These require the marijuana grower to mix the two separate nutrients into one. Using just a grow and then marijuana flower nutrients will produce fantastic pot plants. However, for truly excellent results, adding additional nutrients to your fertilizer recipe is best.
Such as Big Bud.
However adding too much nutrients can cause plant problems. If you suspect the problem with your marijuana plants is a result of using too much fertilizer immediately flush your plants with clean water. Often times this requires a marijuana grower to dump several buckets of water into their plants to cleanse the soil of unwanted toxins.
If your water faucets are crusty with rust your plants will suffer. Use the pH and PPM meter to determine the pH balance of your tap water. A chronic marijuana plant problem could very well be the water itself. Consider purchasing a water purifier.

Nutrient Problem Solver Chart
This handy chart is a guide to determining the possible problems with your marijuana plants when it comes to fertilizer problems. Diagnose the problem very carefully. Do not make major changes to your plants feeding schedule. Instead slowly correct the problem to determine if diagnosis is correct.
Start Here
1a) The problem only affects the bottom and middle of the marijuana plant. Go to #2.
1b) The problem is affecting the upper top of the marijuana plant and leaf tips. Go to #10
1c) The problem is affecting the whole marijuana plant. Go to #6
2) Marijuana leaves at the bottom and middle of the plant are drooping, yellowing, then dieing. Leaf are not curled up. Vegetative growth is very slow. Possible problem is lack of Nitrogen. If not go to #3.
3) Some leaves are curled up or worst twisted oddly. Leaf is yellowing (and maybe turning brown), but the veins remain somewhat healthy green. Possible problem Magnesium. If not go to #4.
4) Brown dead patches around the edges of some of the leaf, which may also be curled. Marijuana plant may be growing too tall. With big gaps between brackets. Possible problem Potassium (K) deficiency. If not go to #5.
5) Leaves and stem are dark green or red/purple. Leaf falling off plant. Growth is slowed and leaves are small. Possibly problem Phosphorous (P) deficiency. If not go to #6.
Signs of Too Much Fertilizer
6) Marijuana plant looks healthy, but leaves are turning yellow, brown then falling off. Possible problem too much fertilizers, over-watering, or insufficient soil aeration. Cutback on fertilizer feeding. Flush marijuana plant with clean water. Check to see if roots are damaged or become a ball. Drive a stake around the edge to create air flow. If not go to #7.
7) Leaves are curled under like a ram's horn, and are dark green, gray, brown, or gold. Possible problem over-fertilization. If not, go to #8.
The plant is wilted, even though the soil is moist. Possible problem over-fertilization, burned roots from too much fertilizer, root bound, marijuana plant disease. If not go to #9.
9) Marijuana plants won't flower, even though they get 12 hours of darkness for over 2 weeks. Possible problem is light leaking into the grow room. Too much nitrogen, pruning or cloning. If not, go to #10
10) Leaves at top of marijuana plant twist turn brown then die. The lights are too close to the plant.
Finally your marijuana plant might just be a weak marijuana type. Do not use bag seed. Instead purchase marijuana seed from a reputable marijuana seed dealer. Great marijuana plants begin with amazing cannabis seed.
