White spots on a few leaves
Nigs4200started grow question 2 days ago
Any idea what these whitish yellow spots are? They appeared overnight. I'm growing in ffof with perlite and ewc. No nutes added yet, just bush doctor cal mag at half dose 3 days ago with great white, recharge, and photosynthesis Plus which was the last watering of 1.2 liters.

white spot reminds residue from spiled watering. i see strange pattern in leaves and colour, reminds magnesium issue starting. leaf droopiness is from underwatering and /or low humidity in grow area. brown spots are either spilled nutes burn or water drop and intesnse light burn.
would say no general big threads, just few things to tune up.

That doesn't look like a nutrient issue, but more like you have spilled water or feed onto your leaf and it has either been burned.
With plain water it can act like a magnifying glass and concentrate the light in a small spot and burn.
With feed, as the water evaporates, the mixture becomes much more concentrated and can burn like this.
Simple to avoid, don't get water or feed on the leaves, especially not when lights are on.

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

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?

Should I harvest in 2-3 weeks ?Hey, do you think my plants might be ready in two weeks ? They're autos in 7th week of their life. I know that 9 weeks is ok for most, but these should take approx. 11 weeks. Do you think one more week of feeding, then flush would be appropriate ? Trichomes are mostly milky white

Late flower issues- chop early?Week 8 of flower (haven't been best at keeping up with diary). Poor girl is deteriorating rapidly but I don't know why. Too late to fix, but too early for ideal harvest. Should I just let her ride or chop early and try to salvage what I can?

Yellowing on older fan leafHey guys, my photo sour d has some earlier growth showing some yellowing in the center of a few leaves. I fed this plant a foliar spray of cal mag plus way back in the 2nd or 3rd week and it got burned on the leaves but does this look more like a deficiency?

Overwatered cubes in hydro? Too close to the sun? or effect of having addHi All, I have issues with my first hydro grow - i effed up. I think i was too slow in the transfer over in the tank. Light is 200 PPFD, EC at 0.6, and barely added any nutes.
Did i manage to overwater some of these plants by having them too close to the net pot?6 months ago
