Purple stems can be a sign of a mag def, but that doesn't mean you have one. Some strains have purple or red stems. Just from experience plants in soil at around 6 weeks start to show signs of it, and really I am just thinking about it as a preventive measure. It doesn't hurt to use it.I noticed some purple stems in one of your photo's. Do you have a lot of them? The reason that I am asking is that could be a sign of a magnesium deficiency. Your leaves look ok though, except for those slight wrinkles. What are you feeding them? Do you add any Calmag to your feed solution? If you don't, it's the right time to start just to prevent a deficiency from occurring. Don't trim the leaves as you need all of them on those plants. Peace
Yes it has happened to me before. It could be an early sign of a deficiency so just watch it to make sure. My LD had purple stems during the winter, but both the ones that are growing now don't.the other plant that im growing aswell dosnt have any purple stems and theyre both from the same plant, Kangaroobunny have you had that issue before? cause i live in scotland and it is fucking cold here, gonna trim some of the branches today as i think its getting pritty dark down the bottom and try and lollipop it. il upload some pics later to show yous how there getting on. cheers for the help dudes
