I have 2 Blue Dream autos in 4x4 tent with 2xvs1000 led lights on 100% 18 inches above plant height. On a 17/7 light schedule. They are 8 weeks old and in ffof no nutes at all yet. Ph in is always 6.5. The ph out is 6.1 I don’t have a ppm meter yet. But the top of my bud looks burt is certain spots. I have a humidifier running and humidity stays about 55% and temp stays about 73-77. Also have a fan running low around the clock.
Looks like natural progression from what people say here.
Though I missed the ones with dark foliage. That is nitrogen toxicity. If you haven’t been giving nutrients, was there any flush when it started to flower?
What size pots are they in and can you get a picture of the entire plant?
I’m not positive but if it’s only on the very tallest point it could just be light burn.
.though at 8 weeks they have probably used all the food in the ocean forest…
But from what I can see it looks very healthy other then the leafs on top of course.
Also do you have some nutes you was planning on feeding?
Ok yes ill put up pics of the whole plant. No I didn’t do a flush when they started flowering I just did the first flush tonight. I plan on using ff trio for nutes. They are in a 5 gallon pot but it like 3 1/2 gallons of ffof.
Looks like a slight cal mag issue I wouldn’t worry to much you’re about 3-4 weeks from f finish so you’ll be cutting off excess nutes in a week anyways
With FF soil, she should have been getting nutes when she started flowering. Now you cannot use Grow Big because you want to cut down to almost no N.
As you can see by the chart below, if it starts from the top down, it’s an immobile nutrient.
A couple of things. She may just be hungry because no nutrients yet.
She could be too close to the light.
But, first, try a soil slurry test to check the ph of the soil (not the runoff… they can be quite different.
So…
Raise the light up to about 23 inches and turn them down to about 75%.
Then do the soil slurry test and report back
