Flowering - What To Do?

So this is my Pineapple Express Auto G13 Labs and my first auto. I am using advanced nutrients grow, bloom, micro and flowering additives big bud and bud candy. Now im slightly confused as to what to do here. I understand that autos are sometimes more sensitive to nutrients and may require lower doses. So the other day i noticed some fading green and hit her with barely stronger nutes.. it was my assumption that it was a Nitrogen deficiency ( not sure if i am wrong in that? you tell me...) but i also started to notice tips burning..so i flushed today..but my fear is that the nitrogen deficiency will get worse

id love to know your input thanks

How far into flower? How's your medium?. It's common for plants to run out of N during flowering. I feed it right to the last couple weeks.

Magnesuim def imo

I noticed you are in soil, and common in these grows is calcium or magnesium or both being deficient. I don't think it is nitro, but a soil test kit is the best way to tell. They are on Amazon for about $20. Check you PH, as that might be an issue also. The bud looks good though. Good luck and peace

Well it's an auto so it's about 6 weeks old - about 1 or 2 weeks into flowering - I'm using promix BX for soil - I have been feeding the micro,grow,bloom every feeding .. And I believe the grow is mostly nitrogen - I have Calimagic but haven't been using it because I was under the impression the AN line would cover it .. I'm more concerned now that I flushed her and she will be without any nutrients until she is dry which will be about 4 or 5 days. Should I mix up some food with a little Calimagic and 1/4 strength nutes and feed her even though the soil isn't dry ?

Also my ph runoff is about 6.2 - 6.3 .... A little low but nothing serious

I think the AN line skips calcium and mag heavy since i have had nothing but problems with it using sensei nutes. I would go ahead and use that calmagic bro because from what i hear you need to have a lot of it in the soil to harm the plant. Also raise your ph because its what is most likely locking out the cal/mag in your plant.

Yeah im thinking magnesium, I believe nitrogen def is much more even over the surface of the leaf, and magnesium leaves green veins, which is what yours seems to have.
