Yellow tips near bud sites
Yellow tips are developing on some of the leaves near bud sites. Is this a cause for concern or a sign of a deficiency? The light is as high up as i can get it and it is on max currently. Also the only nutrients I have added the whole cycle has been small amounts of a compost tea

Deficiency or Burn?
All these girls in manure compost/perlite mix. Healthy through veg with minor Magnesium deficiency in the beginning. Been feeding 3ml/gal calmag occasionally, and 1/2 cup banana tea I made 1-2x a week. Waterings have been at 6.5, just lowered to 6.2. About 1/4 gal/plant 1-2 days.

Leaves full of brown spots
My friend doesn’t have a grow diary but he uses advanced nutrients and feeds when almost dry. He has this problem on his leaves and he can’t seem to stop it. I suggested calmag but he feed it 2ml per litre on sunday and the problem is still increasing. What else can he do ?

Lime green/yellow plants
Ok so my OG Ladies are looking pretty lime green/yellow. I noticed when I mixed my nutes I think I mixed up the a and b bottles I also don’t really check PH, relying on microbes to buffer. I checked it and it’s high. Iv fixed the res mix and upped the dose. It’s been 24h ish…

Harvesting a struggling plant or just letting it fight
Can she be saved or just flush her and harvest what I can? She doesn't appear to be happy. Has some CBD genetics so the lack of trichomes don't worry me. Rest of my garden is fading as well. Flushed em last feeding and they didn't seem to like it.

Deficiency because she starts to flower? Leaf tipps light green. Some purple at the stems.
I have not fed her, just a bit here and there. So I do believe she starts to need her medication. Its going to the end of preflower week1. Symptoms: some light tipps and some purple at the stems. Solution: feed her P and K. could add some CalMag ? Or Still feed more NPK?

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?

Strange leaves on seedling
Hi everyone, I started those two a day later than the others, the cotyledons grew normal but the first set of leave is quite strange. The leaves don't grow opposite, but point on the same side... there are also some yellowish spot on them. I put a photo of the others to compare.

Tip burn yellowing
I thought I had the leaf tip burn and curl handled but it’s really never subsided. My temps are 76 at hottest and humidity around 45 to 55. 1 out of 3 plants shows no symptoms but it’s the least mature. I was trying to flush but that seems to not help. Idk anymore, help!!
