what's wrong?
this yellowing that starts from the edges and ends up drying out the whole leaf is only happening on the hulkberries (the fat banana looks great) so now I just don't know what it could be 😭

What’s going on here?
Blessings grow bros! I’m having an issue not sure what the problem is could you assist? Planted in soil. Feeding them on a synthetic fertilizer mix 20-20-20, CalMag, 5-2-4 organic fertilizer mix. Spraying with Lost Coast based on directions and parasite control. Let me know

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.

Nute or light burn?
Hi guys, does this look like a nute or light burn? I’ve just changed my fertiliser and the ladies have grown quite a bit. This only affects some bits of new growth so I’m a bit unsure😐

How do i fix this.The ph was way to high but i corrected it.My question is do i have to add more nitrogen to the feeding or will the plants go green again by themselves.How long does it take on average for yellowing plants to recover.

Noticed some brown tips showing up. . I've never fed at 100% full strength yet. Is it still to much or a deficiency you think?

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

Overfertilization? What could it be?
Hi guys I'm in the seventh week. What could it be? Out of 5 plants, of five different types, two plants have plagron substrate. The other three plants have a biocanna substrate and do not have this problem. Overfertilization?
