Hey bro. Its cal mag def. But the tip burn, isn't tip burn. Its overwatering or some form of root rot.

Bottom leaves lifeless and yellow
Hi! My plants are in their 2nd week of flowering and some of the leaves at the bottom of the plant (very few in the middle) are starting to turn yellow and they look kind of lifeless. It's very dense in the tent so maybe they don't have enough light? or lack of nutrients ?

Been flushing for the past week, the larger fan leaves are starting too turn yellow faster than I had anticipated but trich's haven't started turning amber yet. All the other sign's point towards her being about a week away from the chop but I'm a bit worried that I flushed early

Is this Nute burn?
Is this Nute burn or something else? Using bio bizz grow, bloom and top max with “all in one” soil. I’ve recently upped the nutes in line with the bio bizz feeding schedule for my soil but it looks like the plant is freaking out at something. Thanks guys

(Mimosa auto in coco) Yellowing tips on new growth
The top of the plant (new growth) is showing some unhealthy signs. The tips of the leaves are yellow and there are lighter green stripes on the leaves themselves. I googled and the signs match to a number of deficiencies, but i lack the experience to diagnose correctly. Plz help

Rust-colored margins and dots. I would like to go back to fertilizing but I am afraid that it is an excess of potassium
Outdoor in the vegetative phase, southern climate. Soil is Biobizz light mix. So far I have only fertilized 2 times with the tripack ph perfect Advanced Nutrients. These rust-colored burns are present on almost all older leaves. Enlighten me please 🙏

Yellow leaves
Hi guys, unfortunately because of an emergency I had to leave my 2 babys with some friends for three weeks. At the bottom some yellow leaves and like burning signs. I don't think it's because of over nutrition. They didn't get any for three weeks. Might be not enough nutrient?

Plant starting to yellow too fast
The crystal meth has started going yellow very fast. The buds still have at least 2 weeks of growth needed to fatten out and pack the trichomes with thc.. I know it is normal to start dying but isn't this a bit early? Should I let her keep going as long as sugar leaves are alive?
