Just switched from veg to week 1 of flower and a few plants are showing yellowing leaves since they have been fed a few times with the flowering nutes. After looking online I think it might be potassium deficiency. It’s only on a few plants the rest look fine and healthy. Any tips on how to correct this?

They look a bit overwatered but I never had that much yellowing plus brown just because of that. Dont know if its because it didnt go that far or because is not the main reason.

prune off the leaves on the bottom. as well as all the dying leaves they won't come back. if you want to you can switch back to veg until you fix the issue. as for ur issue.. it's either being underfed or the ph is off.

Feeding every other day at the moment and ph has been between 5.8-6.0. I thought it could be potassium deficiency but unsure why when ph has been good and using nutes I’ve always used previously

Every other feed? or are you watering/feeding literally every other day?

are these plants clones? They could just require more potassium if they're not clones..i do agree though does look like K def

Literally feeding every other day , they did seem droopy today though so think every day might be best going forward. And yes they are clones. I might flush with ph water then add a bit of potassium and see if it fixes the issue plus feeding everyday

I think youre drowning them... Dont water until the soil is dry or fairly dry, your roots are gonna rot if thats not the reason why theyre like that already.
EDIT: If you wanna water more often put some more coco in the soil or go full coco, also get textile pots, they transpire and exchange humidity with the air. You are also way more likely to avoid rootbound.

I don’t think it’s drowning them as only been feeding every other day I’m not sure I could feed less than that after how they looked today when I didn’t feed yesterday.

Hiya, if you are feeding every other day then something is wrong. How much water are you giving them each feed and what size pots are they in? It could likely be nutrient burn but I am sure someone more experienced can chime in and better inform you. My plants need water about every 3.5 to 4 days, they are in 11 Litre pots and take about 3 litres of water per plant. When they were younger a little less as the root system is still developing.

Hope you get it sorted 👍

Ps: possibly take the advice to reveg until they are cured lol just because even if they survive it will affect you final product. They should generally be fighting fit before flowering starts, if you fuck around with then too much at this stage it won't bode well.

Peace ✌️

This. Also, when you water them so often you discourage root system development. You should let them dry out as much as you can to begin with so that the roots grow in search of water. @Eledin Is right on all counts. The fabric pots are a must 100%

You should aim for each feed being about 20 to 25% of the pot capacity. For example if you have a 10 litre pot you want to be giving the plant between 2 and 2.5 litres of water per feed. Each feed should last a minimum of 3 days (2 if the plants are huge)
