Can you help me how to fertilize?

[pello15]

I have a plant that is in week 3 of flowering, and it has a bit of nutrient burn (or so I think).It is affecting the pistils, which are turning brown. I am watering every 2 days and I was always adding fertilizer. it is right? Have I read people fertilizing every week?
How would you recommend? I was using a 3/6/6 chemical fertilizer.
I have also 2 other organic ones that are 3/1/4 and 3.1/0.5/4.1, how should I do? any advice?

Are you lifting your pot to feel a weight difference prior to giving water every 2days? You sure they need it? And get a fert with higher PK ratio lower N.

Yes, I always wait for it to be very dry, it is in an environment with quite a lot of heat and little humidity, so it asks for water. What would be the appropriate ratio 1-4-4?
Does it greatly affect the quality of the collection if the pistils are brown?

When they started turning brown, did they start from the outside in or from the inside out?

You growing indoors?
If so what light model/brand?
What dimmer setting?
How far over the tops of the plant?
The leaf tips make me think light burn.

I see you have synthetic and organic nutes, remember that synthetic nutes are available to the plants immediately while organics need to break down first.
What brand are the nutes?
