Spotted leaves
Cannaterplovastarted grow question 4 years ago
8 day old seedlings in living soil. They have little white spots on their first set of leaves. Any ideas of what could be going on? All 4 seedlings have spots. I treated them with Mammoth bio-control.

This looks like little burn spots. Are you misting them with the lights on? Those LEDs put out a crazy amount of power and they look pretty close to the plants. I run my LEDs full power but always keep them at least 36 inches from the plants. If you mist them or spill nutrients on them then the light magnifies the droplets and can burn the plants. I am personally anti-foliar feeding. There really isn't much benefit of spraying your plants as long as you have good quality nutrients and an adequate grow medium. The roots do a great job if they are healthy. Raising your lights higher, feeding your roots properly, and making sure you are in range on pH will improve the happiness of your plants 100%. I would also check the plants closely for tiny insect pest with a magnifying glass just to be on the safe side. They usually attack the lower side of the leaves. Little bugs can cause similar damage. Good luck with your grow!

@Cannaterplova if it isnt burn spots as greenmachine suggested then look under the leaves for tiny little specks that are actually spider mites
if it is mites you will need to act immediately with some type of miticide or even some neem Good luck mate

1/3 plants has leaves that are almost pointing straight up. I have read two opposing things. One being that the plant is actually “happy” soaking in the sun and directing it to the bud sites. The other being some sort of deficiency- either calcium or magnesium? Any thoughts?Week 10

The plants are now placed in rows, not on the windowtill but behind & below. This means that they’re:
1. Growing towards the window once again
2. Have parts of them barely exposed to the sunlight.
What do I do?
Do I let them grow how they want to? Should I trim away some leaves?Week 6

Day 4: Leaves have started to brighten and yellow at a fairly alarming rate. With the lower leaves falling off, this looks like a Nitrogen deficiency. Take note of the picture on Day 4 where LSD (the tall plant on the left) is much brighter, and more yellow than Phantom OG (rightWeek 11
