Leaf discoloration and curling
I’m not sure what’s wrong but all my other plants are fine. It’s in pearlite and peat moss and I’ve been watering with ph balanced water. I did use a very little bit of half strength dyna grow but I only did a little squirt.

Day 20 Flower. Leaves curling
Leaves curled over 12 hour light cycle. Ph 6.0. Ppm 950. I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this. I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?

Yellow leaves
Hello, take a look at the pictures please. Leaves are turning yellow and curl. Is this a N burn, or a deficianty from some mineral? Or is this nutrient lockout? Plant does grow well!

What are my leaves telling me?
Is this light burn? Nutrient deficiency/excess? It is only happening on the top leaves, the lower leaves are just fine. The light is rather close to the plant, but she is outgrowing my tent. Thanks in advance for the help! I really appreciate it. 😀

End of Flower, Yellow and crusty leaves ok ?
Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves. Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?

Weird leaf
It seems one of my leaves has become very oddly curled up. It has very slight brown spots with a strangely curled up tip. As seen on Week3-day19. Can anyone identify some sort of problem like excess or deficiency of nutrients?

Too Much Light?
Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.

Week 2: One of the plants still doesn't look good + other beginner questions :)
Second week and one of the plants has weird spots + leaves curled. Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea. Also, when should I start feeding the plants? And how much water do I need at this point? 😥

Leaves turning yellow/pointing up, stem turning purple
Having a problem with one of them.. all the leaves have gone very yellow and are pointing upwards. The stem is also very purple now. Any ideas what this could be? Other than a feeding of bud candy and watering here and there it hasn’t gotten any other feeding. Thanks!
