Started from the bottoms leaves. The old ones first then kept going up the plant. What should i do if anything can be done? Thanks
Giving complete details of your grow would be helpful. Temps, Rh, lighting, soil/medium type, nutrients used and concentration, weeks into flower, etc. Looks like salt buildup as the tops are showing nute burn while the lower leaves are showing deficiencies. Leech the medium with straight water.... 2-3X's the volume of the container at a ph of 6.5 if soil, .3 EC @ 1-2X's volume if coco. Follow up with a balanced nutrient feed. Why i say balanced is because nutrients are antagonistic amongst one another and high concentrations of one will prevent proper uptake of others or lock them out completely.
