This is a magnesium deficiency, right?

Hellow mate, I can see clearly nutrient overdose, perhaps calcium and magnesium are locked, due to pH being too low.
Your next watering, give them plain pH (6.5) with half a dose of cal/mag (Personally recommend plant magic magne-cal ) until you have 20% run-off. Next watering, give them food but at half the dose.

I'm doing an all organic grow. The clones are about 5 weeks old. I give them enzymes with ful-power twice a week, and compost tea once a week. I transplanted them into soil that wasn't allowed to cook last week. The light greenish color had been going on before i transplanted it.

Hi.
Burnt tip is the first sign of nutrient burn, he gave it too much nutrients that's for sure, but the question is, whether he gave it too much of some nutrients, and not enough of others. Other scenario, he gave it too much of all required nutrients and didn't adjust pH, knowing that most base nutrients (organic or chemical) lowering the pH, and when there are very high PPM concentration in soil, it may lose an ability to buffer pH. If pH of soil stays below 6 for too long, it locks out calcium, magnesium and phosphorus but Potassium is fully available.
The only way to know for sure is to collect some run-off and take some readings with TDS meter. Regardless of results, solution will be the same.
I think I've provided a fair explanation. Will you be able to explain, why my advice is full of shit?
