Hey @Canna_ballistic ! I got the same problem on my Green Gelato diary. It was EC problem, I was just checking the income EC. Water your plants as you would usually do. You should get a 10%-20% outcome of water from each pot. Take one of that outcomes and check the EC. If the output EC is bigger than your income EC you have salt acumulation. To help this, you should: OutputEC - InitialEC = Next watering EC. For example, you are watering them at 1.2EC and you get an outcome of 1.4EC. Then, 1.4-1.2 = 0.2 EC. This will be your next watering EC to prevent more salt acumulation. You can also do a flush. But I would recommend first the upper method since it's more "natural". Good luck!

I know everyone freaks when the start to see the bigger older leaves start to turn colors! Buts it’s because the plant is getting for death lol as the buds mature they pull all of the nutes out of the leaves!! To me this is always a good sign as your buds are ripening !! But I would raise your ph up to 6.5!! Good luck 🍀👍

Yellow edge with brown spots on fan leaves I am wondering if anyone could help me figure out what is going on here. She’s been healthy all grow, but in the last week has started showing the weird yellowing/browning on a few leaves. The temps, nutes and light haven’t changed really. Anyone have any idea what this could be?

Bottom leaf turned yellow with brown on edge Hello this is my first grow and had noticed a leaf turned yellow with brown spot on the edge. This is a northern light auto just kicking off with her flowering. I use advanced nutrients 3 in 1 micro grow and bloom and that's all I've ever used. I suspect a nitrogen deficiency...?

Deficiency?Hey everybody, I’ve never really dealt with deficiencies in autos as most of my experience is with growing photos outdoors. Does this look like a magnesium deficiency? These just appeared over night on just two of my larger growing white widow autos. Please let me know, thanks!

Tip of leaves burnt Has been vegetating for a while and growing nice, only noticed these around a week ago and dont seem to be going away. It looks like a nutrient burn? Been feeding it pH perfect Bloom, Grow and Micro 3 times a week (4ml a litre), so didn't think it would be a deficiency. Thanks!!

Is this possible nutrient burn?Sour Kush Day 24 (Coco/perlite) - brown tip appearing on lower fan leaves. I suspect it's nutrient burn. Flushed with 900cc PH neutral water, lot of runoff, PPM was 391 (PPM in 495). Should I cut back on feeding by diluting the nutrient water or by watering less frequently? TY
