Looks mid-late flowering plant, with big nutrient deficiencies. Likely caused by either a pH problem causing nutrient lockout; or from not giving them enough nutrients in the first place.
If pH is 5.8-6.3 you are good. Flowering likes the higher end but the odd 5.8 watering helps let the other nutrients in. Try this first before adding more nutrients.
