This. I think lol.
Calcium sounds about right given the information at hand.
Does it seem to be appearing on the new growth?
Hi I’m using cal mag, same on 4 plants two indoors two out but this is only happening to the indoor grow
Could it be related to my light somehow ?
Are you running LEDs? How much calmag?

Are you checking your PH? I also had problems with my indoor grow. Narrowed it down to over watering and PH balance. PH imbalance can imitate nutrition problems. I would start there first.

I use the same water nutrient mix for all plants and never have this problem growing outside
LEDs make plants hungrier for calcium and magnesium. You should be good at 1ml/L. What’s the whole plant look like?

Apart from the purple stalk on leaves that I believe is due to cold nights when light off she growing well still in veg at mo but don’t want to flip her till I get this resolved
Do you see this moving through the plant? The leaves that are affected will remain that way. Is new growth coming out clean? Purple stems can also be associated with leds. I think all my indoor plants have had purple stems.

Hello I’m in my 3rd week of flowering, I bought feminized blue dream seeds and noticed this today? Did my plant turn hermie or is this normal for blue dream?
Light Source: LEDS
While I’m not familiar with Blue Dream, that plant bigtime looks hermie’d.
I would personally isolate it ASAP until I could find a more definitive answer regarding that particular strain…just to be safe.
I’ve never seen any one strain or plant do that unless it was hermie’d, though…for what it’s worth.

There’s no need to thank me…no problem though lol.
It might be a good idea to check out any remaining plants in your tent, too. They might not be in such an advanced state, but may still be headed down the same route…if hermaphroditing is the issue, I mean.
