What causes red stems in marijuana plants?

Phosphorus and magnesium deficiencies can cause red, purple or pink stems in some cases. Although it’s still not 100% confirmed, growers have noticed that a lack of phosphorus or magnesium usually causes discoloration of the stems, which often come with other symptoms such as yellowing of the leaves.

Do Marijuana plants need nitrogen during flowering?

Cannabis does need phosphorus for flowers, but extra phosphorus doesn’t boost blooms. If you give extra phosphorus and potassium, while nitrogen is short, cannabis interprets the condition as nitrogen shortage and restricts its growth to meet the lower nitrogen level.

What does a nitrogen deficiency look like on a marijuana plant?

What marijuana strains have purple stems?

Violet: Purple strains of cannabis are probably the most popular, such as Granddaddy Purple, Purple Haze and Purple Urkle. Marijuana strains that appear purplish or blue as opposed to the traditional green cannabis, tend to be more fruity, due to the high number of anthocyanins.

Does too much nitrogen prevent flowering?

What does a plant with too much nitrogen look like?

Nitrogen toxicity in plants results in clawed, shiny and abnormally dark green leaves, slow growth and weak stems. A claw is a leaf bent at the tips with a talon-like shape. Leaves often have a strange cupping or curving. Once the leaves become claws, they will turn yellow and die.
