One plant has some brown showing up? Grown in coco.
@Watt-Sun you grow in coco right? Can you explain this?
@CoyoteCody any ideas?
Are you feeding?
May need a light dose of nutrient water, seems leaves are turning brown showing it needs feed.
What’s your current schedule for this plant? Watering, how much , how often
And humidity levels?
Possible light burn?
Light burn normally effects the new growth on top. She looks hungry to me. What is your ph and ppm atm
If you’re not already feeding it’s time to start. I usually start off with 150-200 ppms.
I’m at only my second set of leaves and I am feeding at 250-300ppm. They look hungry to me though. I could be wrong though.
Is your ph correct. Did you flush the coco before using it
Flushed the coco and buffered it in calmag. Only thing I might have messed up on was the flush was with water with ph of 7.2. I started giving light dose nutes first of the week but someone said that was to early so I waited untill yesterday and resumed with half strength sensi coco and calmag, around 400 ppm. My light is a mars hydro ts1000 hanging @ 24 inch. Other two look good. Just slow growth.
By the way I’m growing in canna coco.
Air temp mid 70’s
Humidity mid 50’s or higher
Started light nutes, sensi coco AB, 350-400PPM
18/6 LIGHT CYCLE with mars hydro st 24"
There’s your problem. I grow in coco that comes in blocks. Coco ph is 5.5-6.5 with the sweet spot being 5.8
You have water droplets visible on the plant which under high intensity lights will burn the leaves FYI. At that age I would continue to dome it and 400 ppm is about right. Give it a chance to bounce back.
Looks like ph to me
@HornHead, should I flush canna coco? Some say yes and some say no. When I flushed mine, i really never gave it much thought about the ph of my water being used to flush with. Rookie mistake. I assumed “flush” means to rinse with high amounts of water, is this correct? Here was my process prior to germination, rinsed my coco with roughly 3 times the amount of un PH’d water to coco. Then soaked coco in high dose calmag solution which was also un ph’d. When I say in ph’d water I’m referring to my well water which comes out of tap at 7.3. I’m guessing even tho I watered my seedling with ph’d 5.8 water the coco is way high and will need to be flushed back down with 5.8, would this or could this correct the issue?
Will flushing with 5.8 water hurt the seedlings? Will they be able to handle that much water in coco?
