To much nutrients dude. Water them with only water then start feeding and you will be fixed.

Losing vigor and yellowing
Sorry I don’t have a diary for this grow. I did collect some runoff on one of my girls so hopefully this can help for giving assistance. This is only my 3rd grow and the first 2 went very well but this one isn’t, all plants have lost vigor, are growing slowly and are yellowing.

What could be causing this?
I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far. I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout. Anything else it could be??

Deficiency?
I seem to be having slight yellowing of new growth and some brown spots coming up on the old. Anyone have any ideas what i need to give them? Is this a cal-mag issue or maybe nitrogen? Super newbie and just not sure, thanks! 👍

Is this sight yellowing normal or cause for light concern? No nutrients
Does it look like the new leaves on my 7 day pictures are slightly yellow? Or is that relatively normal with new growth? 20% perlite, 30% coco, 50% organic potting mix. Been really light handed on the water. waiting until soil is completely dry before watering more (1-2 days)

Brown leaves and red stems. Is this a calcium deficiency ?
I had an iron toxicity recently that may explain the brown parts but it may look like calcium deficiency. There are many red stems too but it maybe something else like the bad Ph and overfeeding from the previous month. What do you think ? Thanks !!

Seedling light green, just want her to be happy.
Seedling is slightly yellowing. First ever hydro grow, just wondering what I should look out for. The water is ph 5.8 with fish shit, hyshield, calmag, and nutes according to seedling stage. I even added some extra plain ro water so nutes shouldn't be too strong.

Harvest close but yellowing fast!
Looking at my last pictures, I see the Purple yellowing very fast but, on the trichs pictures, you can't see any amber on her yet. I was planning a few more days before harvest that purple, but could that damage the buds? If it so I would harvest. What would you do? Many thanks!

Can someone give me their opinion as to what deficiencies this girl is showing? She is getting super hungry and is very large. Coco is the medium and she only gets RO water, hardly ever above 1000 PPM. 6.2 is the PH. I am thinking Potassium Def

Is it time to flush or wait a week?
Hey what’s up grow gang, we’re approaching the final weeks of flowers, but I was curious as to if our grow is ready to be flushed, or if they possibly need another week of nutrients, and also the best flush technique for best results. Thank you for answering in advance!
