Yup. Looks like you burned the tips slightly. Just dial it back a bit. I normally won't go over 2/3 the recommended dose. They always put their numbers high.. Hope this helps! Happy Growing! ✌️

Can anyone tell what is causing these yellow tips on new growth on this plant?I noticed my DLI was around 42 at the top of this plant so the light may have been too strong, or it could be a nutrient issue? Using CoM Stonington soil, plant is 26 days old. Haven't added any nutrients to the soil yet.

A deficiency, a toxicity and a toxic-deficiency???Here's what I make of it (and PLEASE correct me where I am wrong!) : The tips yellowing indicates, a nitrogen burn. The burnt brown tip indicates, nitrogen burned to long 😂 The black spots indicate, a P or K issue (as the leaves are otherwise healthy green in color)

Yellowish color at the tips and wrinkles My plant has been yellowing for a day now, I think it is a deficiency of some nutrient but I don't know what it could be, I have thought about buying NPK. At the same time, there are also a couple of leaves that have slightly wrinkled the tip and have been half lowered.
