Is this N deficiency?

[The_Squire411]

Hey guys just after some advice.This is my second outdoor grow and third grow overall so I'm still pretty new. I have two plants going this season outdoors on my parents property, a GH Super Lemon Haze & Barney's farm Critical Kush. The Kush has been flowering for around 5 - 6 weeks and the SLH for probably 4 weeks.

 

I am only able to get up to feed them once a week or so and have been using mainly Seasol powerfeed and half strength liquid potash since flowering. I checked them earlier in the week (Monday) and they looked fine but I checked them today (Saturday) and they have a ton of yellow leaves. So I'm not sure if this is a nitrogen deficiency or something else. I know they start to lose leaves towards the end of flowering which could be the case for the Kush but judging by the size of the flowers on the SLH she's still got quite a while to go so just wasnt sure. I do know that the SLH is pretty thirsty and it's been warm which explains the drooping leaves.

 

 

If you guys have any advice on what to do and even how long you think I've got on either any help would be greatly appreciated. Cheers

try and keep more water up to them, maybe a drip system? keeping them alive 2 more weeks would be my main aim there and see how things are then

Yeah good call, we have rain forcasted for the next few days and temps look pretty mild so hopefully that keeps them happy for a while. Would you still fertilize at this point? Or just give them plain water?

hard to know without knowing the base soil prep, there should be enuf of the good stuff in that soil,  id lean to just water and say the lack of it was a contributor in the leaves yellowing so fast

Looks like they may have been deficient the whole grow , maybe some cal mag ( has a little nitrogen but that’s not what they need now)

P n K is what u need , itchy might be able to help u with something better but a pot ash mixture may help

they are so thirsty, pull back the mulch and top dress with a bag of decent manure and give plenty of water and re mulch.
