JoeNathanstarted grow question a year ago

My lady is turning yellow around the edges of the lower leaves others are dark green. I just did a top dressing less than a week ago I used feather meal kelp meal alfalfa meal and some bat quano. Looking at charts it seems to be a nitrogen deficiency. I know feather meal is slow

potassium deficiency, and if recent week of fertilization is similar to previous weeks, then i feel more confident about it based on weighted average npk values loosely calculated in head.

If those yellow leaf edges turn brown and get crispy then Potassium is your issue. If you are in CoCo Coir, it has an abundance of Potassium. But it can get tricky because excess calcium can lock out potassium. If adding more potassium doesn't halt the progression then it's time to flush and reset your medium.

Is she too far gone or can she come back?Week 8. Biobizz Light Mix, Biobizz Grow, Biobizz Bloom and Top Max (1ml/L up to 2ml/L). Ph 6.2-6.5. Leaves started yellowing just over a week ago so I started to feed with CalMag at 0.6ml/L. Some of the top leaves are starting to die and new growth is turning yellow quickly.

Is this light burn?All my leaf tips are going yellow, even on the bud leaves. It does seem to be a bit worse towards the top of the plant. Is this light burn? I am using 2x 1000w philzon LEDs in a 3.5'x3.5' Tent and I had them at 10/10 brightness. I just reduced to 8/10. Thanks in advance

Yellowing Leaves The leaves on one of my plants are really starting to yellow. To me, this looks similar to pictures of plants in late flower, rather than the examples of nutrient deficiencies. Have I read this correctly, or should I start worrying?

What’s wrong ?This plant has displayed this yellowing in a couple of its older leaves. It hasn’t gotten better with the exclusion of nutrients it doesn’t seem to be hurting the growth of the plant as it has continued to grow over the past week. Is this something I should be concerned about?

Dry or Feed?What should I do to fix my plant? She has hanging leaves and yellowing for weeks. The summer has been pretty wet here, and the soil has been satiated a couple of times. It's getting dry now. Should I wait for the soil to completely dry or try feeding nutrients?
