Good afternoon My first grow on coconut substrate. The edges of the leaves have turned yellow. I give Kalmag at each watering 0.5 ml/l, maybe it’s not enough? Fertilizers Grow 0.9 ml/l Micro 0.6 ml/l Bloom 0.3 ml/l. Ph - 6.0 - 6.2. I noticed problems on the 17th day.

I am on day 53, I know it’s normal for plants to yellow later in flower, mine turn yellow very early like week 7. Some people way later and theirs are still very green. I recalibrated my ph pen week 6. Happened in under feeding too. Makes bud look awful. What am I doing wrong??

Delaying Senesence?
Delay Senescence in cannabis while employing a staggered harvest? Is this possible? I'm thinking about cherry picking my top colas as they are milky and starting to turn to amber. There are also new bud sites that I wish to feed and maximize yield.

Magnesium - Nutrient problem
Do I have Magnesium deficits or any other problem? I started to notice during the last week and it is progressing quickly. The last weeks, pH of drain water was low (between 5,5 and 5,8) but I could increase it until 6.1. Has anyone the same problem? Thanks!

Light yellowing leaves
Some light yellowing on the leaves, more on the smaller nodes towards the middle. Could this be related to my accidental topping, or possibly due to uneven watering? It was very bushy when i tried to water it last, so i am not sure how evenly the soil was saturated.

Dry yellow/brown tips, starting from the oldest leaves
What's wrong with the plant this week? Many leaves have dry yellow/brown tips, starting from the oldest leaves. Is it some kind of nutrient deficiency, and how do I fix it? I tested the pH of the drainage water and it was 6.8, I've flushed it down to 6.2 now.

Can't deal with yellowing leaves in 4th week of flowering
Been having this problem for a few weeks. I suppose its deficiency of Mag and for the last week or so I've been giving increased portion of CalMag (for 1.5l of distilled water TriPart grow 2.1, micro 2.1, bloom 3, Calmag 12ml). Should I give them more time or its something else?

Overwatered - Should i start over?
Heavily overwatered about a week ago. They never really recovered. I fed them some cal mag a few days ago and they perked up a little. Poor aeration in the soil. Last picture is a comparison with my 3 week old blue dream/gorilla cookies. Should i just throw these away and restart

Fatal ovewatering? Will she survive?
Ugh! One of my two plants Is dying. I suspect overwatering associated with some other issue I can't spot properly. 58 days flowering. It was my first flushing session, not a good start. Her sister has no problem. Poked holes in the dirt, raised temp, maxed the fans. What else?
