Yellow tips slightly burnt looking tips on upper part of plant.

Wanting some thoughts and advice on this. This is my AK48 fem. 6.5 weeks old, 1.5 weeks into flowering. I've got some yellowing and slightly burnt looking tips. I fed nothing but water for the first 4 weeks giving calmag every other feeding. 2 weeks ago I have a 1/2 strength grow nutes. I think the yellowing started slightly before that. I skipped grow nutes last week and did just 1/2 strength bloom nutes since I switched to flowering. I fed again tomorrow, what should ingot with. I have the full arsenal of BioBizz products. It's in BioBizz light mix soil. Temps are about 75 degress and my fed PH is about 5.7-6.0 and my run off is 6.5ish.

Anyone?

Hey buddy im no expert but your girls are looking pretty good. Not sure why there's yellow tips if not heat stress or nute probs. All I can think of is maybe lack of calcium, I know you've been feeding calmag but perhaps they require a bit more. In any case I don't think theres much to worry about it. Good luck!

Thanks. I'm not too concerned. This is justy 3rd grow and it's the best looking plant I've had to date. Trying to not mess it up!
