This is very common with P and K toxicity. Excess P and K causes the lockout of micronutrients and calmag. Now, you have to decide how you want to treat that. Your plants just finished stretching, so now is the time that they will be increasing their intake of P and K by a lot. So you can try to fix the problem by giving her a feed of pH'd water only. You could also not change a thing because it's possible that your excess P and K are going to be necessary now that she has finished stretching so the problem may fix itself.

Balcony Auto Gelato with Yellow and Brown LeavesI'm growing this auto gelato in a balcony safe from rain fall and harsh wind, it's the 25th day and the bottom leaves and cotyledon are turning yellow and with some brown traces. I started to use minimum amount of "all in one" fert. Do you think it is overfertilization issue?

Sick leaves, good budsSome leaves look sick. (Last photos at 8 weeks) Is this an overdose? Do I need to fix this? From fertilizers, I apply only ripen. I plan to give it 2-3 times and then flush and harvest.
I know that ripen helps to end life and makes the leaves turn yellow, but not so!5y ago

Leaf tips burned, cut down feeding?Are my plant over fed? I’m currently 5.5 weeks into flowering and my plants are displaying some burning on their leaf tips, I know it’s probably nute burn, but I am wondering if it severe enough to cut down my feeds. I am currently feeding remo at the recommended chart amount.

Yellowed tipsgood evening guys the tips of the leaves (40%) show signs of yellowing and dryness (only the tips). i read that it could be overfert or too much water. I've also read about lifting from the pot (done), checking the roots (healthy), letting the plant breathe out, cleaning the walls of the pot, and replanting. it should be enough? do you think they are the right moves to make?
