The leaves on the lower branches seem to be a lot greener and it weird because of the 2 differnt problems on differnt plants.maybe im under feeding or tgey are locked out.ive never had these probs before
 
Growth around tops looks good and green. Some leaves under the buds are kind of burnt. Last time I had that in my grow tent was because of overwatering. Other than that they look great! I would have given some of the plants with too much yellow some nitrogen. But not too much as at that stage they don't need that much. They could have benefit from N during stretch. But I would still feed them a bit. I m relying on that :

Yea its doing my head in lol this is 1st time ive had so many probs just needa make it through next mth. Just unsure wether to feed them or wait and see if it gets better with water dont have touch time tho i mite just start back feeding schedule with half dose and hope for best woukd hate for them to get stunted

Sounds like a good plan! Don't worry buds look gorgeous and will be fine!
 
The youngest leaves will give information about nuts. If they look too yellow or else its often sign of deficiency or lockout due to bad ph. Maybe you should check your ph and see if it s in range. Most of the time nuts are ok it s just bad ph of grow medium
 
Does that yellowing look like nitrogen to u? Wasnt to sure due to some of veins still being green and the yellowing looks like is from tip inwards
 
What strain is it? What are you feeding her? Are you giving her any supplements? What is your pH going in, and coming out?
 
Dont have a digtal ph meter but the 1 i do have is reading 6.5 and when i flushed a week ago i put some fresh dolimite lime in them
 
Considering the pic above and what I ve seen so far yes I believe the N deficiency starts from the tip to inward.
 
No that is not a nitrogen deficiency, so don't go adding nitrogen right now!

You seem pretty sure. I m no expert. Give us your thoughts
 
Not 100% but im pretty sure its pineapple haze. I had the same plant last time and had no probs with good yeild.11 odd ounces. I was feeding canna flores i think it is.it is organic but i also was feeding light due to soil having nutes.but i would think since it has been 3 mths they should be about gone
 
Yea didnt think so with the veins still green and the way its fading i have brought 2 ppm meters to try help with problem but they are both giving me differnt readings aswell so no help there
 
I have a funny felling they are hungty but didnt want to start feeding to much incase all these probs are due to lock out

I don't know what you mean by the ph meters giving different results. Did you calibrate them? If you don't have any good reference solution you can use coke or pepsi, they both should read ph 2.5. Anyhow it really important to know what your pH is because most deficiencies are pH related, causing a nutrient lockout. As for the pineapple haze strain, they are normally heavy feeders, and they need a as much magnesium in their diet as other Haze strains and OG strains do. But again anyone trying to help you figure what is truly wrong with your baby will have a hard time helping you without knowing what your pH is...
 
Yeh i really need to invest in a digtal ph meter i have got but but is only 1 that u put in the soil and that is reading 6.5.and its the ppm metrs giving differnt readings they are way apart
