Looks like a ph spot. Check your runoff ph and ec levels and make sure your at the proper levels 6.3 to 6.5 for veg. Cheers

I need advice on what to do with this plant. I flushed her a bit and I think nutrient burining is not showing on new growth, what ppm should i feed her?
I watered only last week and mesaured runoff ppm and ph. Water was 350 ppm and 6 ph and runooff was 700ppm and 6.7 ph. Before when i fed her with 850 ppm runoff was 1500 ppm. I would continue to water only but there was a lot of yellow and pale leaves so gave her light dosage.

Rate the Bud - 6 Week completed flowering
So this is my first time growing with using BioThrive grow, bloom, calmag bottle ferts. Would greatly appreciate any feedback on improvements, those 2-3 leaves with yellow spots seem concerning. On 'honest' scale of 1 to 10, how are my buds looking for week 6 in flowering?

1st grow yellow leaves and brown spots
Last two days some big fan leaves started to get yellow with brown spots. Im half way through flowering stage. Is that normal? Can it be nutrient deficiencies if some of these leaves are on top?? It's not overwatering for sure, I'm puzzled :(

Help validating what this is
My plant seems to have developed some kind of deficiency/excess. I researched and think that it's CalMag deficiency, added CalMag to my nutes (1ml/l). Just wanted to check in with the experts here to get a second opinion. The growth seems slow I'm afraid I may have stunted her 🤦

Browning leaves? Did a soil slurry and dropped the water from 6.8 to 6.2. Does that mean it’s locking out? How should I go about fixing this? In peat pearlite and worm castings. Added about 6 cups of lime to the 20 gallons of soil thought that should have helped the ph?

light bleaching
Why are my leaf tips getting bleached still? I have the light 18 inches from the canopy which is what is recommended for veg, and that's only around 400umol/m2s but the leaf tips keep burning. Temps are low if anything, consistently between 65 and 75 farenheight.

Light streets? Or nutrient burn?
Hey, could this be stress from the lights? It starts at the top and barely shows at the bottom. The leaves are turning yellow from the tips towards the center. Especially at the top. It's under a 200w lamp.

Lockout or deficiency?
I have an issue with a girl. Newbie alert. I feel it’s either calcium def or nut lockout. I fed with 1/2 rec BAC grow feed and it didn’t get better, so 2 days after I gave a flush of fresh water.

They were slightly overwatered, the soil PH of 7.1 to 7.3, lacking phosphorus, maybe magnesium to. Branches from the sides are stretching, but I noticed thet lower leaves started to turn yellow a little at both. If anyone knows good advice to help them out, I would be grateful.😅

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 ?
