Your Ph should be between 5.5 and 6.5 and runoff should not exceed what you put in by more than 200ppm. If the leaves are yellowing it sounds like nitrogen is lacking due to the increasing swelling of the flowers.

Is it light burn?
Could this be from light burn or is it something else? Moved my light 15 cm higher for now. Some of the branches are showing purple color. That means stress for the plant right?!

Hello all, I am having some issues with my outdoor grow. It seems the leaves are beginning to turn yellow. It has not received nutrients Iâd say in about a month. The main reason for asking is because I do not want to over correct by adding nutrients if that may not be an issue.

Leafs getting pale, spotted and dying in late flowering.
Fading very quickly, most of the big fan leaves are dying now. Day 66. Happened within a week. Is there something wrong? Been using only rqs pellets and the last 2 weeks some ekstra biobizz grow.

Moin, bei meiner GröĂen Pflanze fangen die BlĂ€tter an von auĂen gelb zu werden und braune Punkte zu bekommen. Ist das ein Zeichen von einer ĂŒberdĂŒngerung? Alle anderen Pflanzen haben dies nicht. Oder zu wenig?

Yellowing leaves
I have 8 plants running outdoors right now. I am feeding 3Xâs a week with the humbolts starter pack. I am getting a lot of yellowing on my fan leaves. Buds look healthy and are swelling. Should I be worried?

Problem with yellowing?
In the 4/15 10am photo taken from above, does it look like the top leaf is yellowing a bit? Maybe hypervigilant, just want to be able to react quickly, if so.

New leaves have yellow and/or curled tips (-> nutrient burn?), and many leaves have their edges curled up (-> root problem?). The pot that I'm using is fairly small and only has a small hole for drainage. Can this develop into a serious problem?
