proxx87
started grow question 2y ago
Any idea what these bright spots can mean? Plant is 2 1/2 weeks old and those spots show only on older growth.

Looks more like a pH issue. Was the coco washed and buffered? Many brands claim to already be....how well they did so is often debatable.

Old/Bottom leaves is dying off at the edge ?
So these are the oldest leaves my plant has, the rest is fine.The edges are dying off and i don't know why, can anyone help ? The Edges aren't really crispy/dry. Is it maybe too much wind ( Windburn ) ? The Plant is receiving a slight breeze and the leaves are all shaking a bit.

Leaves are a lighter green than usual
Sorry, accidentally hit “solved” Noticing the leaves are getting a light green. Leaves aren’t necessarily drooping but there is some slight tip burn on them. I haven’t been giving them full servings when feeding them nutes once a week just to be safe from burning them out

Low PH runoff, dealing with deficiency due to low soil PH. Added lime and PH went from 5.4 to 5.0 after watering. How to raise it safely and quickly?
I have been dealing with a nutrient deficiency so added nutrients.It looked ok but then got a bit worse and I took some runoff readings which were 5.4 and then 5.0 the next week after adding lime to raise soil PH. How can I best raise the soil Ph being that I added lime already.

Leaf discoloration and deformation.
Getting a weird discoloration that I can't match to anything I have seen. Even shows on some newer growth. Leaves deform a bit with it as well. She was flushed to 6.5 PH runoff 5 days ago. Just fed today with 1/2 str FF trio nutes and noticed the abundance of discolored leaves.

I'm entering week 7, what's happening?
I'm entering week 7 from germination. I'm using a soil for herbs/lawns (pH 8) as an amendment—not ideal for cannabis. I'm testing it, but leaves look like this. I fertilize and already flushed. Using 1ml grow + 1.6ml bloom Biobizz in 500ml water (pot is 3.2L).

I have been having issues and believe its the lights
Today I moved my light closer from 60cm(thought my light would be too strong at 600W) to 30 cm after looking at the specs PPFD: 30cm-564μ.mol, 60cm-146μ.mol, Is this the correct thing to do? What can I do to improve my set up?

Why are my leaves curling down?
I have some Sour Diesel autos that are about 5 and a half weeks old. They are just starting to move into flower, and I have some leaves curling downward and slight discoloration. I’ve already amended with extra cal-mag and doesn’t seem like much has changed.

Help me save my seedling!
Hi! My wappa is still looking like she's dying, very pale. The good news is that she still stands even in the sun. The soil is super aerated, vase is felt, and gets a lot of wind/sun. I don't understand why Rhizoctonia is taking over. I water a little (like pic shows) every 3 day

HELP—Trained eye needed for a nutrient deficiency diagnostic!!!—HELP
Can anyone help me with diagnosing what appears to be a nutrient deficiency? I used Jobe's fertilizer sticks (13-4-5) [I know, horrible stuff but its all I could get for the next two weeks] which I diluted to 1/8, 1/4, 1/2 of the recommended amount as per label. CHEERS!
