Yellow/burned tips & curled leaves
I have an issue with some yellow/burned tips and curled leaves. I already suspect that mainly is from light stress but could also be a nutrient deficiency? I´ve raised the lights the max I can and keep it at 80% for 20 hours. Biobizz soil and nutrients. Thanks in advance!

Slight leaf tip "burn"
What do you think is causing this burn on my leaves? It seems to be quite common. and maybe nothing to worry about if it's this minute. but I would prefer to not burn my plants at all if possible. Could it be a sign of underwatering? Light distance? i have a dimmer keepin at 1000

Burned tips
What's that? Could it be cal/mag deficiency? I don't think that's light burn cause it happens on the lower leaves too. Sometimes I can see even discoloured patches.

Got some minor leaf burn this week. Only a couple leaves, I thought it might have been from being manhandled during the LST training, but not sure. What do it look like to you?

If you'd please look at the pictures with 'question' stated below them? This is actually the biggest bud, only it is showing these strange edges. There is (for now) no budrot, i checked. The leaves are firmly attached. What should i do, harvest it? The other buds don't show this.

Yellowish spots ? Magnesium Deficiency ?
I noticed that on some leaves (not the new ones) there were 2-3 yellowish spots. And on a large leave, a point that turns brown. I thought about a small deficiency in Magnesium?

Nutrient burn?
The leaves on my two plants are starting to show signs of burning. Is this nutrient burn? I have no added nutrients yet but I am using Happy Frog soil. I’ve raised my lights from 24 to 28” in case it’s light burn. What are your thoughts and recommendations?

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?
