What is my deficiency or issue? I won't be able to fix it for this grow, but I have seen this issue with some of my other plants during flower. I think I have a zinc deficiency caused by a potassium and phosphorus excess... maybe overfeeding with everything?? Thanks in advance!

I see some burned leaf tips, due to overnutrition and also most likely a copper deficiency.
Most common reason for copper def is when the ph at the roots is not in the correct range. For hydro, a ph between 5.5 and 6.5 should be good.
Copper deficiencies are likely to appear when using heavily filtered or reverse osmisis (RO) water to feed plants since any copper has been removed.
Copper deficiencies can show up with the plant is having root problems or if the plant is overwatered, even if the ph is good and the copper is present in tap water and/or nutrition.
In that late flowering stage there is no need to handle that anymore as your plant seems almost ready for harvest.

Beginning of week 8. Deficiency? Nute lockout? Normal for this stage of its life?Beginning of week 8 and her leaves are showing more spots and discoloration everyday. Is this normal for an Auto in the late stages of flower? Or do I need to feed more? Maybe a flush? This strain says she takes about 10 weeks start 2 finish.

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?

Starting to have an issue with the Industrial plant. Lower leaves are showing a number of bronzey brown spots with edge burn. Any ideas? I think it might be a magnesium issue because it appeared as the plant started flowering. Picture of the leaf above. Fan leaf stems are purple.Week 7

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.
