Tip burn

I agree with everything Ezzjaybruh is saying... you're overfeeding and it's showing in the burns on the tips... I would cut the Bloom A back quite a bit if not cut it out altogether - it's giving your plant too much nitrogen at this stage and can lead to a lockout of calcium... I don't think you need to do a flush just yet - what I would suggest is just giving her plain pH'd water for a week and when you go back to feeding, cut out the Bloom A and cut Bloom B by 25% (you can keep the calmag but only use it once a week - and keep the PK booster)... Good luck!

You’re overfeeding I’d say by pics.. And if your numbers are right for the Athena nutes - you’re without a doubt overfeeding. You’re 50% over the recommended numbers from Athena.. why? Depending what your medium is - decides how to deal with it but I’d cut those feeds in Half at the least.. especially with autos which can be touchy with feeds
