Plants do not grow and leaves curl with some yellow spot

Hello my friends sorry for my bad english
I have some marijuana plants were transplant from soil to Ebb and Flow 14 days ago but the plants do not grow and some leaves have yellow
spot some leaves curling.

Strain: Jock horror
Age: 5 weeks
Previously : It was growing for a month in soil without lighting only sun mostly in the Shade and no care only water from a well 3300 ppm and it was more Healthy!
Now : Have been transplant to the Ebb and Flow 14 days ago with 400w MH

Type of water: tap water 550 ppm drinkable water PH: 8
Type of fertilizer: 20-20-20+TE powder

After mixing fertilizer with water ppm 1300 PH steady at 5.7-5.9 and ppm never go down it rise every day 20-50 ppm
Light cycle : 20 Light 4 dark

So why my plants do not grow and leaves curl with some yellow spot?

Best regards

Water might be too warm* + lightstress from the MH being too close + shock from going from soil to ebb and flow.

Raise the light, change out the reservoir and, add some synthetic B-1 to the nute mix to boost vigor and resist shock. Let me know if it helps.

-EDIT-

What are you using for nutes?

Thank you very much for your quick response.Water temperature: 65-69 F Room temperature: 75 F Light: 5 feet from the top of plant. For nutrients: I grow outside the United States, but the type of nutrients i use is the same one sold at Wal-Mart 20-20-20+TE. I found a company that specializes in the fertilizer industry company sells several types Can you tell me the best one for me?Liquid fertilizer: 7-5-5+TE or 15-10-7+TE Fertilizer powder soluble in water: 19-6-6+TE or 22-7-7+TE or 28-14-14+TE Thank you very much

Your first and second 7-5-5+TE or 15-10-7=TE for veg. Start at 1/4 strength than it says and see how you go...

That yellowing, could you have spilled anything on it? Has the bulb touched it even briefly?

As to the curling; I'm still chasing that answer because it could be for a lot of reasons...

Curling is probably not enough humidity, spritz it with water at lights out...i call those taco leaves...and the yellowing may be slight nute burn

Cheers robert Going to try that myself at sundown. I've been trying to work out this "canoeing" for while...

No prob sworth...also otloble how is the air in your reservoire's? Do you have enough oxygen being pumped into your water?

Thank you all for helping me

Today I went to the fertilizer company but the liquid nutrient is very weak, I have a 55 gallon barrel means I need 1.5 liters every time I change the water in order to get to 850 ppm.I bought RO/filter and the water go from 550 to 12 ppm.

For nutrients which is better 20-20-20 + TE or 24-10-10 + TE all powder I could not find liquid.

1-Amino Acids liquid With Microelements contains 9% nitrogen and all micro elements excluding calcium and magnesium example Boron, Zinc, etc.
2-calcium liquid contains 10% nitrogen and 21% calcium
3-magnesium powder 100% soluble in water contains 48% magnesium sulfate and 16% magnesium oxide

I know that 1, 2 and 3 are all important and I'll buy them all, but what is the way to mix it with water? and how much ppm for each type?

Thank you all very much and sorry for the many questions
