Yellow and purple leaves
I stopped feeding beginning of the week because I had yellow tops on one of my buds. I think it is causing yellow leaves. Does that sound correct? Also I am seeing sort of a purple colouring on some of the leaves. Is that okay?

Papaya - looks thirsty and starts yellowing on lower half :'-(
My very well trained photo Papaya (Nirvana - Citric x Ice) is significantly decreasing in happiness since yesterday. She looks thirsty but the fabric pot is still heavy and moist (watered 4 days ago), also the leaves on lower half turned yellow today. Too much / little of what?

Yellow Borders and Curling inwards slightly?
Some of the new leaves on 3 plants have got slight yellow borders and are curling inward slightly (please see third pic in this week) - is this due to over watering, nutes? or something to do with humidity? Many thanks!

Your opinion?
Today flushing the wedding cake i was thinking that the problem was an excess of nutrients, but instead water was quite clean, around 1100ppm at the first drain, after several flushes water is now on 600ppm. I also raised the lights.. I still do not understand 🤔

Yellow leaves,
I am feeding these plants all the same nutrients. Canna aqua vega and a 1ml/l calmag with a ph of 6.2 So I was wondering why this is happening. The RH is about 50-60 and temp 28°C. Thanks fellow growers

Leaves are turning yellow and dieing. Looks just like nitrogen deficiency. I'm in early flower
Losing a bunch of yellow leaves during early flower. I have WPM but it wouldn't progress like this would it? I think I may have just been underfeeding or my pH is off. What do you guys think?
