Purple petioles and cupping down
So, after watering with root+ 1.3ml/gal and amino extreme 1.4ml/gal and putting in a light that is double the wattage from the one prior it seems they got light/heat stressed. The purple petiole color could be phenotypic as it's striated in the stem too but I'm not 100%. Help?!

Thankfully not my plant but what do you think this deficiency is? My first thought was actually that one plant fungus r something that causes brown circle like spots. This is the top of the plant. No curling to leaves.

Sick plant, could be temp, nutes, too much water?
Leaf tips looking burnt and wilting in flower ... keeps getting worse no matter what. pH 6.8. Raised light. Too many nutes? but a couple days with water only and it's still getting worse. The other plant seems fine. The buds seem OK. Maybe heat? Soil is 69F. Overwater?

Wind burn damage
I have small leaves curling at the top of my new growth and im pretty certain it might be wind burn because of a lot of wind around the plants and sometimes bit direct wind. I just want to know if it will recover well and wether it will damage my growth a lot ?

Calcium Deficiency? pH problem?
Brown spots on some newer growth now on both plants. Canna Terra Flores brings the pH of water down too much even at a half dose. I didn’t think I’d need to adjust pH much in soil. Any suggestions at this point? Thinking to just feed plain water to bring the pH up at the roots

Leaves drooping after transplant
My one plant has been starting to droop and the leaves are wilting down a day after transplant. I know this can happen from transplanting as the plant is going through additional stress but is this what’s going on? If not, any ideas? See photos week 9. Thanks!

Discoloration bud leaves
Anybody know what this discoloration is? Humidity was a bit too high so I'm hoping not some type of mold. The affected buds did get quite a lot of wind and light, so it might be light- or windburn? Any help appreciated!

Which pests do this?
Exactly what pest does this kinda damage? I have my guess, but wanna get other growers' opinion on this type of yellowing of leaves and brown spots. 6 weeks into veg. It started very early on at bottom leaves, once I trimmed them this brown spots appeared on top growth.

I may have over watered or it could be nutrient lockout. I only feed them every 10days to 2wks. I was switching them over from 1 fert to bloom fert by mixing 1 tsp of ea into 1 gal water but I did it 2x in a row. BEST WAY TO FIX THIS ???

White-spotted leaves, any deficiencies ?
Does my plant have some kind of deficiencies? She's an auto at the beginning of the 3rd week of flowering and she's being fed 1 ml./lt of each of the following Biobizz nutrients: Grow, Bloom and TopMax. The one in the picture is the leaf with the most white spots.

Browning on the leaves?
I am worried about the leaf colour I feel like it’s slightly browned on the tips. Interested on what others that know what they’re looking at more than me think. Good chance I’m being over protective. I appreciate you.
