Hello and thanks for looking at my question. I have a DWC Pineapple Express mom and her fan leaves keep showing a deficiency and I cant figure it out. I am thinking calmag. Photos attached, please let me know your thoughts. This is a repost to add more photos.

Thanks for the reply. Its in a DWC 5 Gallon, with 10 inch net pot. Nutrients are weekly, 1400 including 50 PPM liquid Karma and half a dropper of calmag, the rest grow. PH kept at 6.3 and need to replace about half gallon per day.

My guess would be a Nute lockout.
Your tips are clawed and burnt, which points to nitrogen toxicity. Usually when the water is to saline (salty) the plant overcompensates by creating more sugars to cancel the salts, that usually leads to a nutrient lockout. I would suggest you go easier on the nutes, and see if the problem fixes itself, if you see it spreading then add or increase your calmag additive keeping in mind the EC and/or PH of the water.

Clawing on Lemon Cherry Cookies Fast Buds Biobizz light mixDoes anyone know what this Lemon Cherry Cookie might have? I assume it's too much nutritiens because of the "clawing" of some leafs, but it also has brighter green newer leafs, it's in a biobizz light mix, so I thought she can get the dosage by biobizz plan from week 2-1/2 onLeaves.

Advise to flush or feed in VegDoes this is look like a nute burn, deficiency, or ph problem? The two plants that are growing a tad taller have had yellowing tips some curling downward. Don’t want to overreact and cause it to worsen, they’re looking healthy otherwise. Any advise whether to flush or feed?Leaves. Curl down

Leaf-tips going droopy modeAfter my second to last watering the tips of all of the leaves started to droop a bit. I though it was connected to the night-cycle of my light, but it continues to worsen every day. However I only watered after the soil was dry too the touch? Is it really overwatering or else?Leaves.

This margin curl appears to have spread from one plant to 2 of the other 3. So I assumed not pH, not lockout, not nutrient based. Roots all great. I've culled the 3 and there is 1 survivor doing well but what was this? In the diary I mention using Temprid FX, Neem, Spinosad.5 months ago

Maybe PH Lockout?Hello everyone, can you maybe help me? My Black Cherry Punch has some kind of problem. I suspect it’s a nutrient lockout caused by the pH value.
