?
Indoor or Outdoor? Indoor

Soil or Hydro? DWC

If Hydro, Reservoir size?
4- 5 gallon buckets. Currently they are filled just to the bottom of the net pot.

If Hydro, Reservoir Temperature? Temperatures are 69-75. We are using frozen bottles in the water to try and keep the water temperature down. However it is not working the best.

If Hydro, what type of Medium? Using Hydroton

If Hydro, what type of Setup?
DWC- using medium air stones the size up from 2". The air pump EcoAir 35 watt. Each buckets has its own line. We are not top feeding the plants.
The inline fan 400 CFM as well as the carbon filter are outside the tent sucking air from the tent. We also have an oscillating fan inside the tent as well as a humidifier. Humidity was about 30% before the humidifier was introduced.

Size (Wattage) of Light? How Many? One 600 watt light about 18" from the tallest plant and 21" from the smallest plant.

Is it Air Cooled? Yes

Temperature of Room/Cabinet? Using a 4x4 grow tent. Temp lights on 77 Light off 69.

RH of Room/Cabinet? 44% lights on, Lights off 52-55%

PH of Medium or Reservoir? PH was 6.0 for the first few days. Recently we brought it down to 5.5-5.8.

Any Pests? Don't think so.

How Often are you Watering? Have sprayed the plants by the stalk every few days.

Two of the them just had roots come through today.

Type and Strength of Fertilizers used?
Using Flora Gro Series. Currently following the chart. 2.5 ml/gallon of Flora Gro, Mirco and Bloom.

Size or Square Footage of Room? 4 x 4 x 7

The problem:
The plants leaves are yellowing. This is happening to some the larger leaves. Only a few of the new growth leaves on one of the plants started to yellow. Most other new growth looks healthy. Could this be nitrogen deficiency? Are we over feeding the plants?
 
Your plants appear to have a nitrogen deficiency. I would increase your nutrients to Flora Gro 3.75 millilitres per gallon, Flora Micro 3.75 millilitres per gallon and Flora Bloom 3.75 millilitres per gallon and see if your leaves darken. You may possibly be able to use full strength nutrients in 10 days. If you notice yellowing and browning leaf tips that is a sign of nutrients burn and you should slightly reduce the amount of nutrients you are using.
 
Oh and our PPM are ranging 360-400. Is this good for this stage or should it be higher? Thank you for your information. Everything helps.
