yellowing leaves?

So i went and checked on my babies after two days and this is what i found. Some of the leaves on tge majority of my plants have turned yellow and look like theyre dying. I was giving them water every two days and feeding them with miracle grow bloom. I just started feeding them about two weeks ago. Is this a nitrogen defficiency? Or not enough water? Tge pots were very dry since the past two days have been in the 90s. Heres a few pics


Also some of my plants had drooping leaves aswell.

definitely looks under watered, and looks like a nitro deficiency. here's a link to help assist you http://www.420magazine.com/forums/problems-pests-disease-control/81275-cannabis-plant-pest-problem-solver-pictorial.html, hope this help.

But i thought during flowing they dont need nitrogen?

Hey Randy 954: Its been really warm if not hot in your area. When your plants are in flower they really need to be watered once a day. Without question they are healthy and simply need water. The yellow leafs is par for the course at this point of the cycle. Don't get so worried - these plants are resilient. Water will give you robust buds. Lack of water will give you less yield.

They really don't need as much or far less nitrogen in part of its LIFE....You might want to work up to 2 teaspoons per gallon of Potassium (big bloom, etc you know?) that's what will fill out the plant and give you a much better end product.

Marijuana plants need nitrogen through the whole grow. They just need less N and more PK during flowering. They still need small amounts of N too keep the leaves nice and green

Yeah your biggest problem is they really need water (from the look of the pics).

They need water!

If ur in pots and its above 80 degrees you should water daily, just use a lil less water...try to read em bro, lift the pot when its dry and when its full of water and compare.... if its getting light (as in not heavy), you need water

This is not true by any means, I am in 30 gallon smartpots in a greenhouse (80-100 degrees) and I water once every 7-10 days. Your plants look over watered to me, every 2 days may be too much unless you have very sandy airy soil or tiny containers. How big are your containers? Let them fully dry out before you water again, Wilting symptoms of a wet plant can look very similar to a dry plant.
