Have been watering a little less and just defoliating any leaves that were dying off or had previous old nutrient deficiency/light burn since correction. Adding the calcium seems to be helping the new growth and the discolouration is stopping. Starting to see little flower appear on all my sites and the stretch has been quite strong this time around, especially on the 2 clones. Going to keep just watering and look at top dressing amendments in a week or 2.
