Looks like nutrient lock-up to me. I'd use your method of flushing. My rule of thumb is no nutrients until day 21, but I have done it sooner with success.

We've had some really warm weather the past few days. This morning, just before the lights switched off, i saw it was 31.1 degrees C in the grow tent. Are the yellowing leaves a concern? The yellowest leaves are really brittle. I don't believe they're under-waterd.

Hi, this plant is a green gelato automatic from RQS that I'm growing next to my trained plant. I've been giving her the same nutrients and she didn't show any problem until now, its grown 70 cm tall in 6 weeks and it's now flowering. Am I overfeeding her? Already know it's not PH

Yellowing leaves
I have 8 plants running outdoors right now. I am feeding 3X’s a week with the humbolts starter pack. I am getting a lot of yellowing on my fan leaves. Buds look healthy and are swelling. Should I be worried?

Overfertilization? What could it be?
Hi guys I'm in the seventh week. What could it be? Out of 5 plants, of five different types, two plants have plagron substrate. The other three plants have a biocanna substrate and do not have this problem. Overfertilization?

Is this overfeeding or another more complex problem
This is my first Automatic plant culture. I've made some novice mistakes, such as topping the plants. They start flowering about 2 weeks ago, but the leaves are turning yellow with some brown spots. I feed with an old Nutrient I had here. Can that be the problem?

Why do my plants only have that light greenish yellowish look at the top and why is one of my plants also having those sick leaves at the bottom?
2 of my 3 plants are a bit yellow-ish at the top since about a week. Plant 1 also had a couple of sick leaves at the bottom that I did remove. Those leaves had brown/dark spots, felt dry like paper, had very purple stems and did smell more like hay. More info in my report.

Yellow tips near bud sites
Yellow tips are developing on some of the leaves near bud sites. Is this a cause for concern or a sign of a deficiency? The light is as high up as i can get it and it is on max currently. Also the only nutrients I have added the whole cycle has been small amounts of a compost tea

Top new leaves yellowing and twisting.
My problem from the previous question is developing. The new leaves are yellowish and now they started twisting. PH is 5.8 in 6.0 out EC down from 2.0 to 1.75 the lower growth lack this problem, could be light burn? Was 20cm away (150w) Maybe its a deficiency i can’t understand
