i just would go with plain white stuff, you can use carton, paper, or a white foil. I wont go with alufoil or something like that. Because the alufoil reflects the light in weired ways, that brings no good light. The best reflector is plain white. That light is a directly reflected good light for your plants

Tin foil is not a good choice. Here is a nice overview of your possibilities: https://www.growweedeasy.com/reflectivity

Strange leaf deformationHave these strange leaf formation on some of her blades, looks liker the main vein has somehow outgrow/stretch, with no actual green stuff around lol. Several leaves have this. Combined with a slightly general canoeing, could it be from a nitrogen tox ? Growing good though
Cheers

development problemsI'm having problems with the plant. The lower leaves are drying out and spots are appearing. The upper leaves are curling and twisting, and there's an unhealthy color. pH is 6.5, PPM was 600 but I lowered it to 420 yesterday. Suspecting either a nutrient overdose or a pH issue. Check out the photos from the second week (day 10).

PPFD Management -- Am I doing this right? :) (See fan leaf photos for curling)TS1000 (150W x 2), set to 75% at 12-14". "Photone" app (yes, not as good as a PAR reader) reads 580-700 PPFD, so I sense these girls aren't getting as much light as they could. I've read that pushing 900 PPFD is desired (CO2 bags);fan leaves curled. How should I think about this?

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? 😥

What do I do about this fungal infection?Follow up to my previous question. What do I do about this infection? It's fungal. I have crop defender 3, but the plant is starting to lean because of the weight. Help?! She is also killing another set of large leaves. And she's healing, I think, but it's taking too much time.

Help diagnose hydroponic plants! Too much light/heat? Nutrient issue?The plant's leaves on the right are wilting and drying out, while the leaves on the left are spiking. Just did a nutrient/water change but it didn't help, and it looks like growth is being stunted on the right plant. Humidity has been around 45-55 rh and temp 70-80F
