Need help with yellowing leaves

[Weener]

Ive got some blueberrys going but im having problems. Many are very weak and deformed looking ( which is characteristic of blueberry from what ive researched) but the ones that looked stronger are now getting yellow spots on many of the upper leaves.

Im using foxfarm soil, a 250-watt MH light, the room stays between 77 and 81 degrees usually, ventilation should be good...ive ordered a ph reader but im waiting on that, just seeing if anyone had any suggestions on how to heal these.

There are pics of a couple of them, i think you can see some of the yellowing on them...any help would be appreciated.

no plant should look deformed or week..


Your leaves are very very dark green.. this can be a sign of NEAR over fertilization..

Your nodal spacing looks GOOD.. but the plant does apear a bit spindley...

Your containers don't look deep enough? How deep are they..

I would transplant the plants into 3 gallon containers... use PERLITE in your mixture and water thoroughly..saturate your soil.. and do not water again until the container feels light and the top 2-3 inches are dry.

don't forget to add dolomite lime to your soil mix

Ive got them in these little coconut containers that allow the roots to grow through, so i was just going to put them into the 3 gallon containers and let it grow through....it has about 20 percent perlite mixed in with the soil right now

Sorry I could have made my point easier by suggesting that everything seems very very dark in colour in those photos as opposed to just the leave colour:)
