As already said by other users she seems to be overfed plus some light/heat stress. Dim or raise your light to prevent the tacoing and dial it back a little on the nutrients.

Is this a nutrient burn?
What do you guys think. Is my nutrient level too high? Currently in week 3 of flower with my 25liter pots and am ec of 1.5-1.6. Lower leaves look a little burned. Had some issues in the beginning with spider mites.

Getting out of the ideas - VPD, nutrients or deficiency?
I'm getting out of the ideas as the foliar symptoms proceed. Lowered EC down to 1.8 from 2.2, pH in range. VPD is getting problematic as the plants seem to be respirating a lot during the day and it rises tent RH sometimes up to 70% - exhaust duct fan wont keep up. Temps 22-24C

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. 😀

Twisted, yellow/brown tips.
Hi, My plant has shown signs of a nutrient excess throughout its complete cycle. It keeps to the tips of younger the leaves that have a tiny twist in the end. I don't think it's the light as it also affects leaves in the lower canopy. I keep on flushing but nothing changes.

Nute burn?
I have one plant that's browning and tips are starting to point up. I'm thinking this is due to ffof soil being too hot for this one the other 2 dont seem to have problems, though another slowed down and is getting a little twisted. Anything I should do besides continuing ph h20?

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?
