Why are these so sickly

They have all been under 400 W HPS since birth and at about 1 1/2 mos they start getting discolored and spotty. It is 2 moms and a bunch of kids (clones) Medical Blueberry. Planted in Miracle Grow potting soil with a 6 mos supply of nutrients.
They have always been watered with distilled water and now that some are outside they get rain water.
Thanks alot gang

Yellow leaves with brown spots point to potassium deficiency! I'm sorry, these look sad What is your pH? What kind of nutrients have you give your plants, how much and how often?

my guess would be the plants are root bound! put them in bigger pots!!!!!!!!!!

possibly zinc deficient too

Good point! I agree! These plants should be in 5 gallon pots at that size! at least!

that one with the purple stem is in an advanced state of chlorosis (lack of chlorophyll) because of the yellow leaves.
