Nute burn. Brown dry curled up tips on leaves is too much nutrition. Having proper run off when watering helps a lot so no salts are left behind from previous feeding. Good luck.

Seems like Calcium (Ca) toxicity which caused a Potassium (K), Iron (Fe), and Manganese (Mn) deficiencies!!
Overall plant foliage is droopy, top foliage with dark green coloration and some tip chlorosis (burn) - Calcium toxicity, lower foliage yellowing with interveinal chlorosis (green venation and chlorosis) - Iron, Manganese, and Potassium deficiencies.
Try lowering your "Sensi Cal-Mag Extra" to about 0-0.2 ml/l since your "pH perfect Micro" and "pH Perfect Grow" should have enough Calcium in it!
You can even Lower the "pH Perfect Grow" to about 1.5ml/l at this point of the growth.
Hope this helps! Good luck and happy growing :)

Nutrient deficiency which kind and/or light burn?Do I have some nutrient deficiency or light burn or maybe both? Looks like maybe P or K? I changed my light to a HPS and the plants grew much closer to the light so could be too much PAR/heat so I raised the light. I also had started to add Cal-Mag to my feed just before.3y ago

'Claws' on tips just after flowering started. Previous answers help - it is a bit worse. I keep a perfect VPD. What should I do? Flower wouldnt fI'm confused. For the first 3w I used LED as instructed 30-40cm, I had ~43cm,100%dim, everything was fine. When the bloom started yellow claws appeared and still there, maybe a bit worse, with 53cm and 75%dim. Mostly on BPP, one more plant showed her claws today aswell. 😓Leaves. Edges burnt

Am I starving and dehydrating my plant, or cooking it with nutes and drowning it?I was thinking the brown spots were nute burn so I've only been moistening the clay medium and little bit of starter soil with 6.5pH water. Of course the roots don't reach the dwc yet. Is my mistake in using no nutes? Is this plant under-nourished and thirsty?6y ago
