Potassium deficiency. You are running way too much nitrogen in flowering as well. Shiney dark green is toxicity. Which nitrogen can hinder bud development in flowering when too much. Flowering NPK ratio is 1-2-3

Las guachas tienen hambre
Ya hace 4 semanas que dejé de fertilizar pensando que estaba más cerca de la cosecha de lo que realmente estaba. Debería volver a fertilizar con alguno de floración o lo dejo así? Ya más de la mitad de los tricomas están lechosos.

Leafs losing Color, die off.
I could really use some help recognizing if and which deficiencies the Super Skunk has. It's currently growing in an organic soil that's been pre-fertilized and should be enough to complete the cycle. The temperatures are around 23c (73,4F) day and 19c (66F) night.

I keep loosing leaves to some sort of nasty necrosis. It affects leaves at all levels, small and big randomly. I had to remove a lot of dying foliage
At first it looks like a asymmetrical spot of leaf starting to thin out to lighter color then tissue dries and turn black. I have high runoff EC3.3 and I blame Easy boost pellets because I only add rootjuice 1ml/L and sugar royal 0.5ml/L to my water. What is it and how I fix it?

Growth looks like it's stopped, is it time to flush?
2 of my plants look like they've stopped growing now and the calcium deficiency looks worse and worse.. should I just flush then with water for a couple of week and be done with them? The late bloomer looks like it's got ages still, definitely not what I'd hoped for being autos

Will she be ok
Should I worry or should she be ok, watered with plain pH 6 water 81ppm runoff 221ppm no further burn but will this slow her down and as I'm sure it was bloom nute that caused the burn should I even bother with p/k in next few weeks if she can't handle bloom and buddy?

Yellow leaves on nearing end auto.
So we are nearing the end. Now there seems to be a lot of conflicting information out there on yellowing of leaves at this time. Some say it’s fine some say it could be hungry or lock. The bud still seem to be growing so not to sure what to do. I stopped feeding about 5 days ago.
