12 weeks in on plant. Coco coir grow. 2.1.1 nutrient ratio because started feeding at 10 weeks. Major lighting issues during plants young life. Fixed issues by upgrading from 15 watt led to 300 which cause the plant to have a beautiful bloom. Just noticed although, some slight early damage to the lower fan leaves that i have no idea what could be causing. Usual decaying of lower leaves. But also an alarming early redding of the sugarleaves leaftips of nugs on the cola has also suddenly appeared. I am lost as the lower fan leaves look as if their nutrient burnt but the upper leaves could possibly have a nutrient deficiency . Or a possible even major burn as the plant was 12 inches from the light, It seems to flourish at that distance although. If someone could please help me with these couple small issues i would greatly appreciate it.
If your room gets too cold, leaves can turn purple. Another possibility is that you may have a phosphorus deficiency. How to fix Cannabis Phosphorus Deficiency (P) Pics & Symptoms
Thank you but that link doesn't help me determine if it's a phosphorus deficiency or toxicity. I don't wanna start boosting its nutrients if the nutrients are causing the burning in the first place.
What lights are you using? most of the "cheap" leds are cheap for a reason and false advertise about the watts. What's the true wattage of ur leds can you check ?
Tru wattage is 130 watts. Its an VIPARSPECTRA LED light labeled as 300 watts. Should be enough for just one small plant.
Checked ph levels of water before each feeding an kept at a constant 6.5ph. And also even tested the runoff water with a ph strip if that works, strip showed that the runoff was almost same ph as water going in.
Just fed plants a 3-2-1 nutrient ratio hoping to give phosphorus back to the plant. Plant is now severely drooping right after watering, mayb it was a phosphorus lockout and not deficiency.
