A question from a fellow grower:
I am growing my first plants. About 2 weeks ago I cut back the light time to 12/12 under red/blue LEDs and my plants have begun budding. I have been feeding them Big Bud 0-1-3. Within the last 24-48 hrs I notice that although the leaves are green and not drooping they have begun curling from the edges toward the mid-line.
That generally indicates over-fertilization. Flush and apply a fresh batch of nutrients.
Soil or Hdyro? No difference in treatment, but different application, regarding flush.
Question:
I purchased a number of seeds off you guys and the White Widow young plants are showing signs of curling edges of leaves and I’m not sure what I’m doing wrong. PH is 7 and below I have listed the my growing schedule, and have also attached pictures of the leaves I have issues with.
I’m hoping you could perhaps guide me in the right direction as to what I am doing wrong.
Your assistance is greatly appreciated,
