No, this has no sign whatsoever of a phosphorus - or any other kind of deficiency! New leaves will grow in much lighter/more yellow than the older leaves and will "green up" with photosynthesis... Your plant looks very healthy to me! If you are using RO water, however, you're going to need to add minerals to it since it is devoid of everything.. you can easily do this by adding 1/4tsp of sea salt to a gallon of RO water.
Good luck!

GrowingGrannie is right. Your plant is totally fine. Those leaves are just new and are lighter than the older leaves. Just let her be!

Looks like cal mag deficiency to me check your soil pH and run off if that's okay feed it a little if it's off correct your soil and run off pH if your pH is lower than 6.0 plant can't absorb phosphorus calcium magnesium or molybdenum so it shows as a deficiency so feeding won't help unless pH is in order

Brown spots on leaves! To Flush or not to Flush? That is the Question.Hello,
Seeing lots of brown spots developing around middle tier leaves. Reddit is telling me I should flush with 15 gallons of water to get rid of salts around the roots. That seems extreme but if that’s the cure I’d like to know more and can I use my tap water (7.1pH 133ppm)?

Nutrient Correction?04/21 - Noticing some possible nutrient issues with the Fruity Pebbles for several days now. She has much more of a pale green color than the others. I’m thinking maybe just a super small amount of Amino Acids with a little Epsom Salt? Maybe fulvic acid and some calcium?

PH all kinds of fucked up!Urgent update. So it turns out the issues all alone where the soil ph which after testing it was PH 3.2 😳
I have flushed with ph 6.8 water and then added some epson salts bringing the final ph back to 5.6-6.2. I then topped the pot with new fresh compost. Will she survive?

Brown leaves and curled small leaves right above the cotyledonsOn the next day after watering with 0,75 ml/l PH Perfect Grow, Micro, Bloom and 1,5 ml/l Voodoo Juice, B-52 the second row of the leaves (three fingers) became partially brown and the newest lower leaves above cotyledons curled a bit. Can it be some kind of nutrient burn?

Red-tinged yellow spots on one fan leafThis week's pics incl close-up of yellow spots visible on both sides of this one leaf. Soil mix includes diatomaceous earth (I top off each week) + 1/4 mosquito dunk crumbled into bits worked into topsoil. Are spots a sign of fungus? Insect? Too much rain? Something else? Ty!
