Watering question and leaves

[panel350]

Hi Guys and Ladies ,I have 2 plants outside they are 7 weeks old and turning to flower . At the moment here it's 26-34 C during the day and 18-22 at nite the girls are drinking 2.25 liters of water each every 48 hours ,is that normal ??? I feed every alternate watering .Some of the lower leaves are changing as in photo"s, is this because they are old or is there something wrong ???
Many thanks .
Cheers

Looks like a Ca def being that late into veg. Add some calmag to it to stop it from getting worse.

I give my plants, late into flower, 4l of water every two days. That seems light to me at 2.25. Check my signature below for a link on The Proper Way to Water a Potted Plant. It will help.

You may want to back off the nutes slightly as well, which is causing your tips to burn

Calcium and Magnesium / Term used often to lump the two together.

It's typically a liquid supplement that contains both Calcium and Magnesium. Most often it's referred to as Calmag, or Calmag+, Sensi Cal, or Calimagic. Most hydro stores carry something similar as it's almost a staple with most growers. Do a search on the jungle store for calmag and you'll see what it is. Maybe take a pic to the store to show him.
