Bottom leaves yellowing in flowering
My lower leaves started turning yellow and drying out, am I having nutrient deficiencies? My guess would be nitrogen or potassium but not sure, had some nutrient burning earlier so cut down on the feeding a bit.

Is this more nutrient deficiency?
I believe the yellowing and brown spots came from the roots starting to suck up more water than the previous weeks. Do you agree that the Durban Poison had some nutrient deficiencies?

Trouble with autoflower
Hey everyone, my seedstocker Critical XXL autoflower sprouted very quickly and had initial signs of fast growth. Since the leaves have become a lot more pale (week 3) to the point I’m worried. The other auto strain I started looks perfect in same conditions

Nitrogen deficiency? What can I do to fix it?
My gorilla girl xl aut is getting a nitrogen deficiency. I think? Im using megacrop. about a ½teaspoon every watering. Also a 1/16tsp of bud explosion and sweet candy. Should I add more? I have the whole line of fox farm nutrients. Anything from there that would help?

Nute lock-out?
My plants appear to be a yellowish color. I am not sure why. I have tried correcting everything I could think of . Run off pH is consistently 5.8. Ppm/Ec is fine. Light is now at 28in/71cm above canopy only at 70% power. Temperature and humidity stay in great range. I don't know.

On Week 11 Day 74, I've been noticing the leaves turning yellow. I'm assuming because we're getting close to harvest, but after reading more about nutrient deficiencies I'm wondering if I should be doing something about it. I started flushing a 1.5 weeks ago.

Yellowing older leaves
Is this a nitrogen deficiency? It's happening just on the 3 bladed leaves of the plant on the left. The plants look overall healthy, at least I think

Yellow leaves near the harvest
This would be my last week of fertilizer watering. And the plant has the leaves turned to the side and with yellow spots. Sign of lack of zinc? I would start making the flush from Friday, is it recommended to start now? In about 2 weeks I will harvest (I tried to water today)
