Could really use some advice here. The tops of this plant are starting to fade out to a lighter green and some of the stems have purple lines going up them. This is my first grow and I’m sorta researching and guessing at this stage of my experience and don’t wanna assume the wrong thing.
This auto is at week 6, and has been grown in Fox Farm Ocean Forrest, with a bit of dolomite and about 35% perlite.
I am feeding it the Fox Farms trio nutrient line which consists of Grow Big, Big Bloom and Tiger Bloom. It’s also given CalMag about twice a week with regular waterings.
My last feed, I gave it 2.5ml of Grow Big, 7ml of Big Bloom and 7ml of Tiger Bloom with an additional 3.5ml of CalMag. I also added 1tbsp of molasses. All mixed into 1 gallon of water. This is roughly 50% of the Fox Farm recommended dosing guide, with a bit less Grow Big at around 25% as I am trying to phase it out. The settled ph was 6.52 and sat at 713ppm.
Yesterday I started to notice the fading at the tops a bit more than the past couple days. Some leafs were showing some slight fading in between the leaf veins with developing brown spots. This seemed like it could of been a CalMag issue. Today I had to water it again and gave it 1 gallon of water ph’d to 6.61 and 4.5ml of CalMag. PPM was 303 after adding the CalMag to my water (which sits at 170ppm out of the tap).
I’m growing my plants under a QB and this light green fade is only at the tops of the plant, and most of the lower growth that isn’t directly under the light seems to not be affected. I’ve seen photos online of plants that are too close to LED’s and they exhibit this light yellow/green fade at the tops. This plant is the tallest after stretching and at its closest cola, it’s 14in under the light. Lower colas sit about 18in to 24in away. I have the light just about as high as I can put it given the other plants growing in my tent not being as tall.
Does this appear to be a nutrient deficiency, or could it be related to the light distance? I’m not sure if it could be a deficiency off the bat because of the feeding it received this past Saturday. So I’m a little confused. The lighter tops started recently, probably within the last 3-4 days. It did not seem to be an issue when the plant was further from the light.
