Brown spotsWhat is this? It's affecting newer growth, first or second set of fan leaves off thee top of the colas. Also, this drooping, is this stress from the light? This is the center of my tent, and would appear to only affect tallest colas of this plant.Leaves. Curl down

Leaf tips are browningCiao tutti,
What is going on with these leaf tips?
It’s the third day of their Flush & It can’t be NutBurn, or the color of tips doesnt look like NutDef!
Is the light stress?
If this de-coloring continues, will it effect the buds & final yield?
ThanksWeek 12

Is 8 oz of water about right for 3 weeks old plants? Also thinking about LST, is it a good time to start that now? Also is buying nutrients worth it when it comes to harvest? Or is it more dependents on the power of the light ? Thank you for any advice 💯🙏🏼Week 3

Day 4, after emerging. Is this coloration on the cotyledons okay?Humidity is 55 - 70, temp is around 20-24c, 50w full spec led
It's my first time, and i think i have been watering it too much
I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?Leaves. Color - Yellow
