Got 3 photos. 2 in the ground 1 in 7 gallon. On all 3 the fan leaves and older leaves turning yellow at a pretty rapid rate. Prob losing 15 leaves a week rn. Purp is deeper into budding and not so bad. But should I hit them with a dose of grow big to sort it out? Or no?

Leaf changed color and spotting, help!
Any idea what I need to do to fix this? I think I over fed and then I recently did and RO flush. Then I fed it calcium herkley and harvest recharge in a little general organics bloom.

Fan leaves turning extremely yellow late flower
Hello. Day 61 of flower, Green Crack 2.0 by Humboldt seed organization. Soil based. All of a sudden all the fan leaves are turning yellow. Trichomes are clear, no exceptions. Is it from finishing or did I mess up watering/nutes in the last couple of weeks? Thanks in advance.

Guys what’s the opinion on flawless finish for flushing. I have read on many forum sites that it does not do anything does anyone have any experience with such a solution. I have used it for the first week to flush the plants and I will use it for two days of the second week.

Yellowing on leaves tips. Should I start feeding her?
Some yellowing appeared on the leaves this last day. Temps and humidity are controlled and ok. I haven't been feeding her, she has been growing on light mix for the past 25 days. Im thinking its time to start applying some nutes. Or could be something else? Thanks!

Should I flush? (Overfeeding)
I think I have overfed my 2 dwarfs. Theyre showing signs like very stringy skinny new growth and yellow leaf tips. Theyre still growing and I dont want to stunt their growth, so all I want to know is if it is necessary to flush. Please tell me how to flush if so, thank you.

Fellow growers, after a few weeks of beautifull growth, I now start to get yellowing leaves which dry up and starve. I am. I am doubting between a lack of nutrification or over nutrification. I suspect the latter (biocanna nutrients and soil). Any ideas? Thanks!!

Grey leaf tips
Booth plants are showing some kinds of burn and I am not sure if it is nutrient burn or light burn or if there is something missing. Looks a bit like MG deficite but shouldn't the plant take that from the soil in that state and age?

Leaves looking a bit discoloured and wilting slightly, what could be causing it?
Leaves are drooping a bit and slightly discoloured, especially when comparing it to the other plant. Also, a couple seem to be growing at a much slower rate, is this anything to worry about or will they catch up? TIA

Identifying the cause of stress
Does anyone know what I’m seeing with the leaves in these photos? The closest I’ve been able to guess from online resources is maybe sulfur deficiency, but to my eye it doesn’t seem to quite fit any of the broad categories. Perhaps just general under-fertilization?
