My First grow need some professional help

they look pretty good. I don't see any deficiencies from the pics.
those brown leaf tips maybe a little bit of Nute burn.

In veg you don't need no 20-20-20, best is 20-10-10, and bud would be 10-20-20, see the difference, but getting a good tomato organic mix from your  best local garden store is the way to go, later if you need to top up the nutes best is to foilar feed, or suffer the expected nute burn, and a serious learning curve 
Right now I'd flush with 3 times the volume of each pot with air temperate Ph neutral water, allow to recover overnite or 1x day in dim light, then continue,....no nutes for 2-3 weeks or until you see an active recovery.
 
Cfl's still put out shit light, get your plants to within 2 inches or so of the tips, keep a temperature gauge in there and maintain 75f/25c at about 65%Rh

 

Their looking pretty good. Make sure no water drops are left on the leaves when your lights are on. Light refraction through water droplets will burn the leaves. The tips are showing signs of potassium deficiency. Your in flowering by the looks of it. Reduce your nitrogen, increase your phosphorous and potassium. If it has progressed, flush with plain water, wait 2-3 days, feed with minimal amounts of nutes. Find a food with an N-P-K of something like 5-30-20. Also, here is a chart to track future deficciencies.

 

 they are autoflowering then, stay on the light schedule you are using.

 

if they are in fact autoflower, keep on same light schedule, do not top(again), and you will have a small yeild any way(if they ARE autos').

 

Did you start them from seed or where they clones? Do you know the strain? If from seed, did you buy them, have them given to you, find them in a bag of smoke you bought? I am only guessing that it is an auto from the way it looks. Small and flowering after only being 1 2/2 months old.

 

pics #2,3,4,7 all show 2 limbs branching off of the main stalk at about the 3rd node. This is usually an indicator of a plant being topped, the top growth cut off to force lower limbs out and up. If in fact it IS an auto, topping will slow growth and reduce yeild.
