Hi there ive got some girls going and they were going pretty good until recently we just had 2 days of rain which i thought wouldnt be too bad as it was only light, but now my plants are yellowing and im lost for why?, would it be nitrogen deficiency or pests? I water every 3-4 days and use river water off a farm as theyre in the bush and too big for me to bring water from home, theyre not in flowering yet they will be in the next 2 weeks though, i dont use any fertilisers really only liquid blood and bone every now and then when i can be bothered bit slack on my part. What can be done to help? Any help would be much appreciated.

Weed plants need NPK but also require calcium and magnesium, I suspect that’s what’s missing on plant in first pic. You’ve got multiple issues going on too, but the “when I can be bothered” comment deserves addressing. You take time to water but don’t feed, what’s the point? Most soils alone do not contain the nutrients to feed each plant species or crop from seed to harvest, water only does not cut it. Now if you were in a well prepared supersoil or living organic soil then yes it could be a water only situation but those soils must be built over time

Hi @213mfw420 and welcome to the best cannabis forum in the world! 
This looks like an iron deficiency caused by too much rain. This happens a lot to people outside in a rainy springtime climate. Drainage is all important when planting outside. This should clear up when the planting bed dries out. I suspect that the soil is loaded with calcium and nitrogen, and now that the rain has mixed all of this together in a soup in that wet soil, the iron is being locked out.

The water i use is river run off and its hard to determine the ph and nutrients in it so figured itd be better to just use that water when the plants need water and every now and again take bottles down with fresh water and feed them with blood and bone
