yellowing leaves

Hello, im growing indoors in soil. 3 months old, strain Crystal queen. Using General hydroponics nutrients. She is still in vegetative stage, about 70 Cm tall. Im keeping her untill I manage to grow a few clones before she goes into flowering. The humidity in the grow room is at 40%-45%. Temp is around 76-78f. I have 4x 24w t5 6500k and a 250w cfl 6500k lighting from the side.

I have been giving her 9ml bloom and 6ml micro with water every 2-3 weeks.

What is causing this?

She got hot

What do you mean hot? Too much nutrients?

Phospherus. Lock out. Looks like she got locked out by ph. A bit of advice. Give a very small dosage of bloom food in the mix the k helps with health. Keep the veg food and bio root. Some superthrive will make it snap back. Also ph can also lock out nutrients. You should check ph looking a leaves usually if lockout from n it is dark green. My best guess is ph

I took a ph sample fromthe run off water and it showed betweeen 6 and 6.5 to my eyes.

And it seems some of the newer growth is going through something aswell, some of tips are yellowing on the top canopy.

It's time to feed

I feed her yesterday right after i noticed these new growths. Also she seems to maybe be too large for the pot she is in. 10L pot 34cm tall. The plant is almost 80 Cm tall.

Ya. I would say a nice repot. You could enduce flowering a week or so after repoting. I would also start a transition nutrient tea. I don't know what soil you have and what the values are but. You need a bloom supplement to get all the nutes requiered. Very little at first and then maintain your veg nutes. Your ppm should be around 10-10-4 in inert soil. Which I use. And start with cal mag . Then start raiding away the nitrogen leaving only enough to form new buds and the remaining. Ppm is for p. A sweetener in 2 weeks is good to

They eat tons of p (phispherous when they flower. And heavy flower is incredible
