Phosphorus deficiencies cause dark splotches on leaves and can appear at the bottom of the plant on some of the oldest leaves. Learn to spot & fix the issue.
What is the position of those fan leaves. If your plants are bushy and this lack of light can cause this and . Or if those are the highest ram leaves then you have
By The Normally the grower is the best candidate to make a accurate diagnosis to find problems and find solutions.
lack of nutrition can be in different forms
1- you don’t give enough fertilizer
2- you give a lots of fertilizer .
3- Ph not suitable for the medium you are using ..
. Adjust your ph , don’t add any fertilizer
And water the pots till you runoff 30 percent of the water .. later add the nutrition you use and water those plants ..
Add a calmag solution to your water to make sure phosphorus is more available to the roots ,, lack of calmag interfere with phosphorus intake of the plants .
Remove all damaged leaves to help you notice better new bad reactions

A model describing the interation between these two nutrients on the basis of root respiration, ion affinities and the precipitation of calciumphosphates in the immediate proximity of the roots is proposed. During root respiration hydrogencarbonate ions tend to keep calcium ions away from the root growing points. Uptake and translocation of phosphate from the soil to the growing points secures the uptake and supply of calcium. Accumulation of calcium ions at root surfaces may precipitate phosphates and thereby hinder uptake of not only phosphate but also of calcium for a short time. The consequences of this sequence may be very pronounced because calcium is not retranslocated in plants.
