How much daily watering is necessary for growing tomatoes inside greenhouse in black plastic bags?

Little seedlings/plants need a light watering each day - if hot twice a day. Bigger plants need a good watering each 2-3 days. For pots - you need to check the top 10-20mm of soil to see if it is wet or dry. If dry then water. The size of the plant and pot will decide how often you water. You want your soil moist not wet wet. It is a bit of trial and error until you work it out.

Had to say what your problem is, too much water, too little water, too hot. Maybe start again.

6.5 is a common pH level for vegetables and works for tomatoes.

Look up ph levels for vegetables on the net. Then you will know for all vegies.

My tomato vines are full of fruit, all of it green. I've often had the problem of ending up with lots of unripe fruit at the end of the season so I was wondering it there is a sure-fire way of ripening the tomatoes on the vine before the first frosts?

I have usually dug in some mulch and let it rot, put a bit of lime on and some fert N- 15.3 - P-4 - K 11.7. I know this is high N and will be using one with about 12 N 3.5 P and 14 K in the future (recommended by fert company that supplies to a lot of commercial growers of veggies around here). From the above I generally have very strong looking plants - I will say I realise I should cut back on the N and will be in the future. I have just started to make some compost the last few months. On a replanting now, I'm putting on about 3 x 20 liter buckets of compost/mulch per sq meter and adding lime and some fert. Will see how that goes - still probably too much N. I'm also adding some trace elements and Epsom salts to my soil. It should be good soil lol
