What will Cause This on my leafs

From what I've been reading I've seen seem those symptoms in 4 cases:
1) Boron deficiency
Leaf Color:
– Pale leaf color
– Purple or darkened leaf color
– Dark brown spots on leaves
Leaf Symptoms:
– Browning or burnt leaf edges
Plant Symptoms:
– Thicker growth tips
– Slowed growth
– Twisted or abnormal growth
2) copper deficiencies
Leaf Color:
Edges Appear Brown or Burnt
Pale Color Leaves
Yellow Leaves - New Growth
Yellow Leaves - Lower, older leaves
Yellowing Between Veins
Dark or Purple Leaves
Red or Pink Color on Leaves
Leaf Symptoms:
Upper Leaves / Newer Growth Affected
Lower Leaves / Older Growth Affected
All Leaves Seem Affected
Leaf Edges Appear Burnt
Leaf Tips Appear Burnt
Leaf Tips Die
Slow Growth
Twisted Growth
Abnormal Growth
Leaves Curl Under
Wilting / Drooping
Plant Symptoms:
Weak Stems
Slow Growth
Twisted Growth
Leaves Curl Under
Other Symptoms:
Buds Not Fattening
3) PH fluctuations
4) light burn using LED gives same symptoms from what I read.
Non of this is from experience, just what I am reading so it might be wrong... anyway one thing I know is you need to check PH and TDS as they are crucial to determine most problems. Good luck

Sometimes wrong PH creates a blockage of nutrients, which leads to the roots not transfering the nutrients in the soil. So I'd suggest you first check the PH; if the readings are within limits start treating for deficiencies. If PH is not within limits fix it and see if you notice any improvements, I am treating some of my plants now from low PH and some plants showed improvement in 3 days.
I honestly don't know, but it depends on the soil, in general from what I know 6-7 for soil is good, coconut coir and hydroponics 5.5-6.5; but better you ask someone that used the same soil as you are using

Usually when feeding and you get cal,mag & phos def, then its a sign of low pH.
Next time, mix & cook some dolomite lime in the soil & if you plan to use that setup again then you'll stop having those problems. The soil should be stable before flowering

SPL I did put lime in the soil it's slow.acting lime lady said at garden shop I wasn't sure and that's what she said to use I wish they made a desolving table for ph one from 5.0-7.0 just put one in each gallon u mix and bam good.to go lol but what should I have pH at like 6.2

If you added lime then it will take a week or two before it starts slowly breaking down, normally a healthy amount of lime should keep you near or at 7 which is fine with organics but don't over do it.
