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 :)

Can I use magnesium sulfate foliarly?Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect.
I should add Dolomite Limestone to the soil this week.

Leaves burned after spraying a cocktailTo repel aphids I sprayed garlic infused in alcohol with water, already did this few times without side effects. But this time I added several drops of tea tree essential oil. Is it possible that the essential oil has burned the leaves so much or is this some nutrient deficiency?

Bio Grow burn vs Bio Grow boostHi, it seems like she keeps getting nute burns as soon as i give her Bio Grow, even at half dosage (1ml/L).
She has only 10 more days of veg and i wanted to boost her, what if i stop giving Bio Grow altogether until flowering?
Is the tradeoff worth it? No burn but less growing?

Is it time to feed nutrients now or can I wait?I have not given any nutrients yet but I'm wondering if I should.
1. Are these really signs of nutrient deficiencies?
2. Which nutrients are missing?
2.1. My guess is P, N and/or Mag, Cal. Is that a good guess?
3. Is BioGrow a good choice to address these deficiencies now?

Yellowing edges and brown tips in 7 week of flower.Hello, fellow growers. Need some help. I'm in 7th week of flowering and upper leaves start yellow with burnt edges. The lamp was too close(30 cm) for 3 days. I raised it to 50 cm ten days ago, but the symptoms are stil progressing. Is it light burn or potassium deficiency?

Grower questionAny ideas what the issue could be?
Few weeks into flower. Dealing with fungus gnats and have kept the population very low.
Temps do get high, at most 95 (hot I know). I cranked down the lights to their lowest setting (100 true watts LED).
I have adequate air flow.
