someone diagnose my plants please... what's wrong?

Hi Guys,

Can anyone tell me if there's anything wrong with my plants?

I have some yellow dots... and some leaves have purple color on tips... some unhappy leaves and some curling...

Thanks..

info about the plants:

3 Plants

I am growing in a cabinet, indoor

I have two fans. one powerful exhaust and a small fan ventilating fresh air in.

My watering schedule is once in every 3-4 days..

The PH is around 6.5 and the heat is around 23-28 Celcius Degrees. The humidity: around 25-35

I had planted my seeds about a month ago. And now in the "Vegetation Stage" and waiting for a couple of more weeks before going on to 12/12 flowering..

The lighting is with 8 Light Bulbs (i am using white wiselite 72Watss (5300 Lumen) each for vegetation, will then place yellow daylight ones for the flowering)

For the nutrition I had used a root solution once.

Now I use a "N" based vegetation solution by BioBizz

Where/how did you check the temperature? Check the temps at the plant tops if you haven't yet. The spots forming on the leaves are probably from Phosphorus deficiency. Other than that, they look very nice. If you haven't flowered this strain before, keep in mind that it will likely double in size before it's done. I'm not sure what type your bulbs are but I doubt they'll support plant parts any further away than they are now.
