Looks like early P def to me. Have you checked the pH of your medium? At 38 days, you are into flowering and P demand is higher. Do you feed every time, every other?? 1.5 ml/L Sensi Bloom really should be giving her enough food, but some plants are gluttons, and sometimes it's problems down below restricting uptake. Really need to know the medium pH. Do you have a PPM meter? What ppm are your feeds? Also, do you pH adjust your feeds before feeding? pH is something you have to monitor and adjust to get a problem free grow. Give me a little more into and I will see if I can help.

It sorta looks like you bleached it with nutes sitting on it...IMO

Hey, Sorry for being so vague, I was fuckin lit when I posted this thread

I feed every time and she has been drinking 300ml-500ml. I live in a hard water area.

This is my second grow and I am embarrassed to say I have not once checked pH of soil or feed. I have ordered a pH pen, that should be arriving tomorrow.

After my first grow the top of the list of things to do differently next time round was to start monitoring pH levels. As everything seemed to be going ok it just slipped my mind..shame on me for getting complacent.

Thanks for the help and sorry again for lack of info in first post.

the whole plant pic looks good.my very bottom leaves often end up looking manky with sitting ontop of soil/getting nute splash/then a lil later no light.hard water area could end up having high ph and high ppm readings.
a ph pen is one of them things some folks can get away a lifetime without needing,others need to use every feeding.whilst others only use them once in a blue moon to double check things.
when people run into plant problems PH is often the first question.often overlooked,but a handy tool to have.very few of us had a ph pen before we had a seed.
good luck.

... Mango's- naughty! you promised you'd watch that f'ing pH next round! ... what you need as well is an Accurate 8 soil pH pen, to test actual in-pot pH,.. meters are for liquids only, and I think I barked about the lousy run-off method for pH testing,... So, question is, if you have a simple lack-of issue, or if the pH is off enough to start locking up P,... the catch is, if it's locked out, it's most likely too acidic, and adding more nutes will make matters worse, not better! Since you're stuck here, when you get you pH meter, you can test some water-only run-off collected from a clean saucer to at least get some idea of the pH without having to do the whole run-off test and calculation deal,.. if she was worse off, I'd say do this anyway, but for now, water only until that meter comes in and you can test,... let us know what you get!

@Waira I know mate I am a very naughty boy.

Thanks for weighing in, I have a soil pH pen now on order too.

Water only until that meter arrives

I sometimes have that sort of leafs,but I'm really messy guy with watering feeding and there is water all over my room,so I think its something with that related(if you have high ppm tap water like me)coz you girls are looking super healthy!

fuck, did I write "pen"?? I meant probe, but you got that I gather! .... are the symptom progressing fast, or creeping along? And did you find an A8 unit, or the equivalent? If you're in the UK, it may not be under that name specifically, but I've seen folks get the same probe via Amazon or something-? ... if it's advancing fast, you may have to resort to a run-off test, inferior as it is, and a pain,... but it'll al least give a ball-park estimate and tell us if it's OK to boost the PK some, or not,...
