Over watering? Pot Bound? Need more information. Have you been fertilizing? What size pots? If they are sky rocket this is normal.

I just finished transplanting 60 tomato plants due to bad soil,never had this happen but went on the cheap and paid for it...now using pro-mix bx which should turn them around.

I have my grow light at about 4 inches from them and they are in 5 inch peat pots with miracle grow potting soil. I have been useing seaweed neptune harvest every 2 weeks on them. I took them off my heating pad because they were drying out quickly. Should i leave them on it or do you think i need to keep them moist?

Going Green

Nutrient deficiencies also cause chlorosis. Nitrogen is a vital component of chlorophyll so inadequate levels of this element make leaves turn yellow. Iron deficiencies cause chlorosis between the veins in leaves while the veins themselves maintain their green color.

Too much or too little water can cause yellowing. Under water stress, plants shut down internally and cannot transport nutrients to the leaves. Chlorophyll production can be affected causing loss of color.

Low temperatures can affect leaf color. Under cool conditions, chemical reactions are slowed and, again, chlorophyll production may be reduced.

maybe overwatering, i would letthem dry out a little and when the soil feels dry to the touch then water them thoroughly, and wait again to the soil dries to the touch, do not fertiize them, the miracle gro potting soil i believe has fertilizer in it already and that could be what is browning your leaves...jim

a couple questions......what variety?---some curly top varieties naturally and normally flip and curl the topmost leaves.
Did you have a nice day and decide to put them outside?--sometimes the initial bright sunshine will hurt the flourescent-light developed leaves.
When young plants are placed outside its very common to get yellowing due to cool soil temps, too much water, or root damage during transplant---did you repot these indoor plants?
I'm sure theres lotsa other possible causes like PH etc also...a dose of miracle grow will eliminate any nutrient or ph issues as the cause but may increase the too wet possibility.......G
