Are these babies sick or need more/less nutes?

New here and hoping for some help. There has been some yellowing and blotches on the babies lately. Could someone take a look at the pics and tell me what they think.

Thanks for any help/advice...

Soil: 50 percent Fox Farm Ocean Forrest / 50 percent “Black Magic” potting soil (used BM for years outside with good results …same strain).

Pots: 6 inch round and deep.

Lights: Eight 40watt, 3300 lumen flours: Daylight (6500k) mixed with “Sunlight” (5000k) overhead and CFL’s which are “cool white” at sides as supplements.

Water: Bottled spring water at room temp.

Temps: 70-74 degrees.

RH: 41-54 percent with fan running.

PH: No idea… no tester.

Strain: Supposedly Jamaican, from an old farmer friend who brought back the originals years ago.

Age: appox 7 weeks.

So… thus far the original soil mix has been fert with Fox Farm “Peace of Mind” organic fert (5-8-4) after 1 month as suggested by Mfg.
Added Bat Guano (10-2-1) at six weeks for a nitrogen boost and with each watering the water is mixed with “Bio-Grow” Molasses (2.0 - 0.1 - 6.6) says it’s safe to add to each watering.

are those leafs just on the bottoms?

Those pics are of fan leaves about one third up from the bottom and sometimes it happens in the middle also. It seems to maybe be progressing upwards, but does not seem to affect any new groth at the nodes.

Just looks like a low light situation. You should start flowering right away as your new growth is only happening at the expense of older growth.

.... or get an HID.
