Wedding Cake nute burn or possible P deficient with yellowing slightly down the edge? Also may have N toxicity with curling leaves? Blueberry also has slightly burnt tips, both plants have yellowing in the oldest growth. All in diary pictures. Thoughts? And how do I fix it?

Too much nitrogen?
What does that mean? Maybe too much nitrogen or too much nut at all? If it's too much nutrient you think is better feed once with nutes once with ph water or every time fed with nutes but one time half of the dosage?? Idk please let me know

Possible Nitrogen Deficiency?
Is this a nitrogen deficiency? I had a yellowing leaf or two at the bottom of the plant which have since dropped off, but rest of the plant is looking patchy now. I have just switched from fish mix to bio grow.

What kind of deficiency is this?
It has been like this for 5 days or so. It looks to me like Iron deficiency but I don´t think that´s probable. I flushed her in order to get rid of salt excess but she didn´t recover any. TIA

After water + applying fertilisers BioBizz flowering week 4 (see chart) the leaves turned dark and in a few hrs started yellowing. The runoff EC usually is a little lower than solution EC. pH around 6,25-6,5
