Help with hempy feeding

I am currently 22 days into 12/12 flowering using hempy buckets. I'm using the GH simple drain to waste schedule just slightly more aggressive. 1.5ml grow, 8.5ml micro, 11ml bloom per gallon supplemented with 2.5ml liquid koolbloom, 10ml florablend, and 10ml floranectar. I feed every other day for 3 cycles then feed str8 water with about 50% runoff on the 4th cycle. I noticed a slight bit of tip burn, just on the very apex tip of a couple fan leaves. I think this is due to overnuting but im not sure if it is the strength of my nute mix or the frequency of feedings. I am going to reduce my nute strength for tonights feeding and see if this works but I am wondering if anyone experienced with hempy knows if that is the problem or if it is the frequency of feedings. I'm learning as I go so trial and error is my only teacher, but I really don't want to overdamage these ladies. I have pics in the grow journal in my sig, the plants appear healthy and are packing on bulk but I read that the 1st sign of overfeeding is often tip burn. Any suggestions or comments are appreciated. Cheers

I noticed when the lights came on tonight some yellowing and pretty bad leaf burn on the blackjack. I gave str8 water tonight and will do so again next watering. I think it may be the strength of my nutes so I am gonna back those down to 1ml grow, 5ml micro, and 8.5ml bloom with the same on the supplements. I'll see how that works and maybe try to bump it up a little at a time till I find that goldilocks zone. Here is the blackjack.

And here is a strawberry.
