Is this normal deficiency?

Hey there, it's a zinc deficiency, your pH isn't good.

N,P deficiency don't listen to these fools 👇

You did use the vegetative nutrients up till last week that is why you got this deficiency. I see that you did switch to the flowering nutrients already so that is good but I will recommend a flush for this extreme deficiency. So you need to flush the pot with the potvolume in water with the right pH (6.2 will do) and with the right EC (1.6 will do) with the vegatative nutrients. Have a nice grow! 💚

I advise dialing down on your nutrients. Autos don't take as much nutrients as photo. It's natural though when giving them nutrients that the leaves turn yellow.

Hi 🙋‍♂️, A Little Bloom fertilizer in flowering stage will fix this issue 👊 she will not be green again, but she will stop getting bleached leaves. Happy growing 👊👌👍

From the photo it looks most like a potassium deficiency. The yellowing starts along the edges of the leaves and the tips, while the veins stay greener. That pattern is pretty typical for low potassium, especially during the flowering stage when the plant’s demand for K increases a lot. It can happen if the plant simply needs more bloom nutrients, but sometimes it is also caused by pH being slightly out of range, which makes potassium harder for the roots to absorb. I would check the pH of your water and runoff and make sure it’s in the proper range. If that looks good, slightly increasing your bloom nutrients usually helps correct it. One thing that often works well is a foliar feeding. You can mix 1 liter of water with BioTabs Boom Boom Spray and add one small drop of Kali soap to break the surface tension. Then spray the leaves and especially the undersides of the leaves. This helps the plant absorb nutrients directly through the foliage and can improve the situation quite quickly. Overall the plant still looks fairly healthy, so it should recover once the potassium availability improves. 🌱

Potassium deficiency. Not normal, not magnesium issues.

Hi there.. From the pictures, your plant shows clear signs of nutritional imbalance. While some yellowing (senescence) is natural at the very end of flowering, the visible patterns here highlight specific deficiencies rather than just a simple end of life. Here’s the analysis of what your leaves are expressing: The likely causes 1. Potassium (K) deficiency The most striking symptom in your photos is the yellowing and browning of the leaf edges (the margins), while the interior remains relatively green. Why now? The demand for potassium skyrockets during the flowering phase for bud development. Appearance: The tips and edges of the leaves look "burned" or scorched. 2. Magnesium (Mg) deficiency We also observe interveinal chlorosis: the space between the veins turns yellow while the veins themselves remain dark green. The cause: This is often due to a pH issue. If the pH is too low or too high, magnesium gets "locked out," and the plant can no longer absorb it, even if it's present in the soil. At Week 8, you’re approaching harvest. If only the lower leaves were yellowing and falling off, that would be the normal "senescence" (the plant drawing on its last reserves). However, since the edges are burning on the middle and upper leaves, it’s a sign that the plant is hungry for minerals to finish its flowering. Good luck and keep it up!

These pictures are from 12 days ago... seems a little fishy. diary is out of order... is this even a real person/current grow? Sorry, but too much shady shit goes down here that such things create doubt. The diary looks like some sort script failure. Looks like K-def pattern, but foliage is a bit lush, so lockout is possible. Veins look dark, which isn't a great sign - maybe some irrigation habits are wonky or you let water stagnate for long periods of time before using... is that a blueish hue in the leaves? That'd point toward p-deficiency. insufficinet info, old pictures... who knows.

DAT IS NOT NORMAL IN ANY STAGE!!! I WILL🙏FOR DAT!!!!

From the photos it looks like magnesium deficiency (interveinal yellowing on older leaves), which is quite common in mid late flower. It’s not really “normal”, but it happens often when the plant needs a bit more Mg or Cal-Mag. I’d add a small dose of Cal-Mag or Epsom salt (MgSO₄) and keep the pH around 6.0–6.5 so the plant can absorb it properly.
