Copper spots on mature nodes. Day 64
WulfBludstarted grow question 4 years ago
I am seeing some copper colors starting to come out on some sugar leaves near my more mature bud sites. Started today on day 64. I have been following fox farm nutrient schedule and watering every 3rd day with PHd after adding nutes at 6.2.
Is this normal or a nute problem?

hey there Wulfblud, that's calmag deficiency, you can tell by the rust color and the newest leafs being affected first. that's because these are immobile nutrients so they dont travel at all. increase micronutrients in your feed to compensate. You can also reduce your light cycle , under intense light the plant needs more calmag , so that could be a root cause. Hope this helps ! 🚀

Generally, rust-colored spots on marijuana leaves indicate a deficiency in magnesium or calcium.

Brown leaves and curled small leaves right above the cotyledonsOn the next day after watering with 0,75 ml/l PH Perfect Grow, Micro, Bloom and 1,5 ml/l Voodoo Juice, B-52 the second row of the leaves (three fingers) became partially brown and the newest lower leaves above cotyledons curled a bit. Can it be some kind of nutrient burn?

Red-tinged yellow spots on one fan leafThis week's pics incl close-up of yellow spots visible on both sides of this one leaf. Soil mix includes diatomaceous earth (I top off each week) + 1/4 mosquito dunk crumbled into bits worked into topsoil. Are spots a sign of fungus? Insect? Too much rain? Something else? Ty!
