Please take a look at my first offspring

[ActivatedAlmonds52]

Looking for a net now. Does it matter what it's made of? Is metal fine? I probably worry too much.

 

[Lesso]

Metal gets hot under a light. Not good

 

[SubmarineGirl]

I love this one. It can be reused very easy and has some stretch It can be adjusted to fit a smaller tent as well

It's been a week since topping. I just changed the bulb to HPS and switched to 12/12h. I'm in the process of installing a net. Wish me luck, boys.

Some of the lowest leaves are getting yellow and falling off. I can only assume that it's because of the topping followed by switching to flowering and the fact that they're getting barely any light. Everything that's about ~10" above soil is fine, though, except for a few small dark spots.

I completely forgot I had Aptus Fulvic Blast (fulvic acids, iron, zinc, manganese, copper), so I added a little bit of that to the water and I'm going to use it once a week from now on.

Normal in flower. Nothing to do with topping.

Oh! Good to know. Although it started happening pretty much as soon as I switched.

Can I shine my phone's flashlight on the plants for a few seconds while the HPS is on? It's hard to tell what color they really are.

Yes and you can shut off the lites for a moment if needed too

Week 9. Not seeing any problems. The only issue is still the lack of space. As you can see in the pic, I finally put up a net. I'm also "reining in" some of the tallest shoots with small pieces of the net.

 

[ActivatedAlmonds52]

Slooooowly getting there. I'll start using Bloombastic (phosphorus pentoxide, potassium oxide, iron) in a week.

 

[ActivatedAlmonds52]

Who left the fridge open? It's getting frosty in here!

 

[SubmarineGirl]

Nice AA

 

[RosterMan]

Very Nice

 

[ActivatedAlmonds52]

Week 16 overall, week 4 of flower. I'm starting to wonder how many g's I can get out of this. I have no idea as this is my first grow.

I don't know what causes the black spots to appear (pics 3 and 4). Lack of sulfur or potassium? Overwatering?

Cal mag

 

[SubmarineGirl]

My guess is low PH causing your plants not to have access to the calcium they are getting. Have you done a PH runoff reading lately?

Hmmm. I've been supplementing them with CalMag and pH+ daily for most of the grow. I'll up the dosage a bit and see what happens.

Also, I'll use just water tomorrow and do a pH test

my bet is that your PH runoff will be lower than is needed for your plants to accept the calcium you’re putting in.
