Vpd has been pretty close to ideal, the pot had 1 gallon less soil so could be missing out on some nutrients? Possibly Potassium? Otherwise not sure what it could be. Does not appear to be N deficiency because the leaves are affected from the top too. What should I do to fix this

Pure and simple potassium deficiency.
Add a p/k booster to your routine or up your dose if already using one.
GrowingTrannyanswered grow question 4y ago
The tips burning is caused by nutrient burn and the yellowing is caused by nutrient lockout.
From now on you need to use nutritions that are rich on phosphorus (P) and potassium (K). You can use a PK Booster like Organoman adviced.
Make sure that your pH is in the right range otherwise the plant will be unable to absorb the nutrients. The right pH for soil is 6.5

What are my leaves telling me?Is this light burn? Nutrient deficiency/excess? It is only happening on the top leaves, the lower leaves are just fine. The light is rather close to the plant, but she is outgrowing my tent. Thanks in advance for the help! I really appreciate it. 😀

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

Leaves are drying up and turning yellowHello,
Something bad is going on with my Hulkberry plant. I think it might be due to giving it to much fertilizer.
Here is how it looked 2 days ago:

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?
