What is this def.

I meant a cannabis dosing chart. Not for the brand canna.

I'm thinking I might cut down 1 or 2 so I can get another plant or 2 in there.

Out of 4 plants only 2 have issues. The other 2 are doing much better but they are further from the light so I assume that's why.
I had a feeling my light was too close. I should have went with my gut. But I kept reading that I wanted to be as close as possible. I guess it's a learning curve. Ugh

1000 watts is a lot for a four 4 x 4 tent. I am growing in one and bought a 600 watt dimmable setup even though I had a 1000 watt light already because I was worried about heat and the issue of the light being too close. You can only raise the light so much. If you need to you can remove that "V" bracket that's hooked to the light where you hang it from and put a sturdy piece of wire instead and gain three or four inches of height if you need.

If the plants were burning, the tops of the buds above the leaves showing the issue would be damaged. It's definitely a ph/def issue. In soil you want to test runoff and adjust your feed accordingly. Feed a few points higher or lower to adjust.

I run DE's as low as 18" without burning.

I do have a little light bleaching on 2 tops.
I do think it's a combination of my light height and ph.
Maybe even nuteburn.

I'm going to dim down to 600 for awhile and see if that helps.

This red widow 13 is definitely more finicky then the bag seed I've grown in the past.

The damaged areas on leaves can't be fixed. It might be smart to raise the light and get rid of plants that are badly damaged. Frankly, I doubt if it's pH if you're not using much fert and haven't given any in a while. How can it be pH? If you're in soil be careful how much you give of fert as soil will retain nutrients for a while. Don't use a hydro feeding schedule for a soil grow. That will be way too much if you do.

From what understand promix should be treated as hydro or Coco.

Just transplanted 2 gg4 2 star pupil and 2 loompa goos into 3gal pots.

I amended some bone meal and lime into the promix along with a little Epsom salt.

I've trimmed off most of the bad damage. The buds still look like they are swelling and growing everyday so I'm going to keep them going. At least for now.
The lights at 600w and 20 inches from tops.

I just remembered just before this started I noticed my ballast was only set for 750w so I cranked it up to 1000. I should have just left it alone lol.
Live and learn.
1 redwidow 13 and a second generation genetics blueberry x stardawg look great.

Edit.
Even with as bad as these plants look they are getting very frosty at 4 weeks. I'm going to run rw13 again eventually and treat her better. She has a heavy yield potential from the looks of it.

Is your 600 air cooled? How far do you keep it.?

Just measured and I'm 15 inches away with a 600 watt. Air cooled hood. Fan blowing directly across under the hood.

In my little low ceiling room I am usually at 18" and happy plants with a glass enclosed ventilated blockbuster and 600 w. Hps.

Ok thanks a ton. I'm going to keep it at 20 in. At 600w for a bit and give them some tlc.
My spacedawg x f4 blueberry is frosting up nice.
I'll get a pic up tomorrow night of all of them.
