Purple leaves and curling sides.
RichBud420started grow question a month ago
The previous week started the problem with CalMag issues.
I started use the Plagron product.
Now the plants looks better, but appeared some purple pieces and the sides curling up.
Can somebody explain me what is this?
Need I worry?
I updated my diary for share details.

To me it looks like its from cooler temps. but if that not happening then need to look at your feeds. Are you giving them enough, are you getting a good amount of runoff when you feed and is your PH on point. Ph looks ok to me. but without a EC or PPM value for your feeds its hard to tell.
You diary states your useing a SF-G3000 for a cycle of 20/4 and this is a bit overkill IMO.
The official site is suggesting a 50-60% dim at a 12" hang height for 18/6 in Veg.

I see purple in my leaves sometimes with heat/light stress. moreso if younger tneter leaves are exposed to more intense light. noticed this with my liberty has when i opened the plant up under the scrog The stuff in the center that had no light got a similar red/purple fading. It could be completely unrelated to what you have going on just a tid bit. Overall shes not looking bad no need for hasty moves

Plants don't have enough basic nutrients in general. The purple is from lack of phosphorus.

I don’t personally really get overly concerned with purpling leaves. It could be either the plant is genetically predisposed to have purple traits or cooler night time temperatures can also cause this.
Purple leaves is just a change in pigmentation and nothing to really worry about. As long as the plant is happy and healthy overall, I don’t see a reason to chase the problem.
So no stress. Don’t change your game plan. Just carry on as normal. Everything will be fine.
