purple stems

If you have a look at my cash crop she is doing the same. I have read it's a sign of high exposure to the sun which is still good anyway as the leafs are not forming any stains nor going crispy. Reading online it just says it's a good sign that they are receiving plenty of light, in theory only the more exposed to the lights should be red. So if you see that the stems which are not receiving as much light as the centre ones have not turned red, then it validates this theory. I have checked my plant and it's exactly like that. Only the centre bits are red, the branches a bit further away from the light are all green. Nothing to worry about, it's all posivite. A bit like when having "praying leafs". I think you can just take it as if you have found the sweet spot for light.

It never hurts to flush he lot of you think something might be up. Just water with pH'ed water for a few days and see what happens. I hope this helps.

Wish you had a diary for this one! Sometimes, red stems just go with the genetics but not this time, I'm afraid... the red stems are indicating a lot of stress - and from the color of the leaves, I would say they've gotten way too much nitrogen... so you've got a toxicity, not a deficiency... If you had a diary and I could take a look at the nutes you're giving her, I could make some specific suggestions - all I can do without the diary is to tell you I think you need to do a flush as they are REALLY dark green and that much nitrogen is going to cause a calcium deficiency in the near future. After you flush and let her dry out, reduce all heavy-nitrogen nutes by 3/4 and the rest of any nutes by 1/2 for the first feed... going forward, you can take the other nutes back up to what they were but cut the heavy-nitrogen ones in half and leave them there... Good luck! (and please, start a diary!)

Nitrogen toxicity, but the rest is good, too much nitrogen in your diet. Acapulco Gold is great strain , no purple roots as i know, so just slow down on that part of feed. Too dark leaf not efficient. Happy Growing !!!

Hi there It’s perfectly fine mate a lot of strains tend to have purple and green stems on the bigger fan leafs its just the genetics 👍 Best of luck 🌱
