look like bigger plant is suffering from magnesium deficiency, and smaller plant is probably rootbound and suffering from nitrogen deficiency. https://loudclouds.co/wp-content/uploads/2016/07/marijuana-deficiency-chart-jorge-cervantes.jpg

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?

First Grow Help And Feedback
Hello Grower, OG Kush Flower Day 24: Lollipopped and defoliated 10 days ago. Can/should I defoliate again? The buds seem like they could get more light. Also, I noticed some sprinkles on the top leaves—could this be from too much P/K? Any tips and general feedback are welcome!

Is this nutrient burn?
As a beginner it is hard to classify that: Are the brown tips a sign for nutrient burn? Or rather a deficiency of something? Soil pH (out of whack) 7.4ish. Fighting that for weeks now... Soil EC ~ 2000 µS/cm. Crazy Hills fertilizer as scheduled. Thank you!

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?
Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

Leaves burned after spraying a cocktail
To 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?

Nute burn? How to handle?
Hi, i guess i made the typical newbie mistake and over-feed a little bit. The plant started to get some brown/yellow tips, mostly the upper part of the plant. Is it enough to just stop with nutrients and stay with clear water or is there anything else i can/should do?

Bio Grow burn vs Bio Grow boost
Hi, 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?
