Hi guys!

I desperately need help with my cacti plants! I bought them on New Year's as a bunch placed together in one pot. About 4 weeks ago I noticed that they suffered quite a physical damage due to lack of space between them.

I divided them in 3 pots (followed the flow of root system), but now I see that they are changing color as well. They also keep tilting. I watered them 4 weeks ago and a bit last week. The soil is a sand-orchid soil-house plant soil mix. The drainage should be good here as 30% of it is sand.

So I have 2 questions:
1) Why are my cacti changing color to light green?
2) Is there anything I can do to cure them from physical damage?

I appreciate your help!

Here are some photos.

What kind of light area they getting?
What is the temperature range?
These clues will help us to figure out what is going on.

Hi Bill!

Thank you for a quick reaction!

I live in a loft space. My plants get a lot of light throughout the day but all of it comes from the top area. I am trying to solve this with plant growth LED lights. The temperature ranges from 59 to 68 F (15-20 C).

Any ideas on how to act?

Temperature range sounds good. I am sure it will be a bit warmer in the summer.
Heck, I was in New York for 58 years. I was on Long Island on the south shore. I felt a need to answer.
Well and broad spectrum plant light is what I would recommend and as many lumens/lux/ foot candles as possible.
Check out my bio. I am growing mostly orchids under lights and I am trying a few succulents. Here are images of my set up and a plant. These are under 48"-2 T-5 tubes at 15".

I got them from Gardeners Supply. Look online. They were not cheap but I am very pleased after two years!! Each shelf has 2 tubes total, 6 in each of two plant stands. Each shelf is 18" X 54" with a sturdy 2" drip tray.
12 tubes in all, about $100 in electricity total each year to run lights from 12-16 hours depending upon season.😎

Welcome!

You can't grow a cactus in sand, soil and orchid mix. Drainage is important but, unlike orchids, cactus roots need to dry between waterings. Sand really isn't a good additive for cactus as it tends to pack and hold even more moisture.

The wounds will heal leaving dry spots but will always be visible. You can always tell when a cactus is getting enough light because it will grow slowly and the tips will be as wide or wider than the old growth. Your plants are starting to show signs of etiolation (stretching towards the light). Here is some more information for you:

I missed the part about growing in "orchid soil".
Get them into a cactus mix that is readily available from a garden center, nursery or places like Home Depot and Lowe's.
