Sup @grammer. Do you have any pictures? Without them it will be hard to recognize what is wrong with your plant.

hi my friend, it looks to me a deficit of nutrients.maybe pk as u entered the flower stage your plant will need a full supply of pk and call mag.adjust your ppm to about 1000 with PK solution and I also use some foliar pk as it is best assimilated by the leaves and works with me. Try to gradually increase during 7-10 days in your watering and keep watching the new leaves as the damaged ones will never recover and you should also gradually take them out. Let me know if it worked out.

It is difficult to know for sure which particular nutrient it is lacking. However, in the flowering stage you will need a lot of phosphorus. Any bloom fertilizer will have the appropriate amounts of phosphorus and potassium for this stage. In addition, if you use hard water you will likely make up any other nutrient deficiencies.
