New ak47 leaf problems?

hi all
Just started 4 ak47s in hydro pebbles that are currently vegging under a 250w hps. Transplanted Wednesday into the pots in their jiffy cubes. Do the plants look ok in colour or does it look like the deep ridges on the leaves could be problematic? Thanks in advance.

Need to start feeding them

Ok cheers, would a 15 minutes flood be good for them every 3 hours when the lights are on?

Does anyone know what these spots are? Also how to get rid of them?
Thanks all

it could be Manganese Deficiency.
youre plants are looking hungry,make sure you give your plants the correct dosage of food,at the correct ph.
between 5.5 - 6.0 pH.

Does that mean I can vary the ph between 5.5 and 6 or just choose a number between the two and stick to that number eg 5.8

Nutrient Def ... are you feeding just water???

No I am feeding them I have another 3 but this one has spots on the leaves

Can I vary the ph then between 5.5 and 6.0 or stick with one ph number throughout the grow?

Help!!!! It’s getting worse I don’t know what to do

Having similar problems. My plant is getting these discolorations on low to high fan leaves. Check pictures; it's not that bad but I'm confused. Haven't used many nutrients other than some dynagro I used yesterday but these symptoms have been around for a half week. I'm in ocean farm soil with 2 Gallon pots

Sorry here are pictures
