Looks like a cal mag deficiency. Would check soil ph first then address it if ph is in range. Good luck 🤜🤛

Still to early to tell? Noticed yesterday and have slightly worsened today. Not sure the issue but potentially magnesium? Getting close to top dress also.
Only on 1 of 3 plants so far. On older growth after getting dose of Recharge the other day. Maybe an N problem as I also use 484? Or mag? Using CalMag every other watering in RO at 150ppm as the soil has some cal and mag. Also getting close to top dress time maybe something else?

Exaggerated texture and discoloured leaves
Hi Guys I’ve notice that some of my leaves are extremely rough/overly textured with slight discolouration, almost looks highlighted or over exposed in colour with some light yellow/ brownish visible. The plant looks alert just a bit odd. It’s only the 1 plant of 2

Nutrient Deficiency
I could be wrong, but it looks like my leaves are starting to show signs of deficiency or am I just being paranoid?

How many times could/should I defoliate these Cobras? The Last photo shows a before & after which took place on May 31st and since that time, she has regrown to the point prior to defoliating. Should I repeat another defoliation? Far too many branches are shaded, again!

Can anyone help sort out the issue I'm seeing on the lower leaves? I think I'm either between nutrient burn or potassium deficiency? I did up the nutrients a bit this week when I saw yellowing, but also have had high runoff pH the whole grow. Though haven't seen any other issues.

Leaf Discoloration
I woke up this morning to only one of my strains having discoloration on the leaves. Still looks extremely healthy but I don't feel like I'm overwatering and I'm definitely not over fertilizing. Need help before problem gets exacerbated. Thx in advance.
