Greenishstarted grow question 7y ago

What's going on with the discoloration of my leaves in the photos? From my googling, it seems like it's a nutrient deficiency, but I don't know if that is happening because the plant is nearing maturity or I need to give it more nutrients.

hello, you have phosphorus deficiency in phase 3, you need urgently to give this nutrient, otherwise the leaves will burn and fall, and will affect the buds. Greetings

Runoff pH is high, plant is not vibrant green and there's a leaf deformity.Guys, if anyone knows, my coco runoff pH is coming out at a constant 6.8, should I pay attention to it? I feel like it should be lower and that's why the color is not as vibrant as it should be. Also, one of the leaves has a deformity, maybe it's genetic maybe it's my doing?

Pale upper leaves - what is it?Overnight the top leaves of 2 plants went slightly pale, so assuming not nitro deficiency. Growing in Coco veg week 5. I just upped my light intensity but not much, and I did erroneously flush 2 days ago with pure water but gave a good feeding the next morning with normal nutes

What do you say, how is this beginning of the 5th week going?Week 5, 3.2L pot (I know it’s small) and about 8h direct light. Removed sick leaves from leaf miners, now spraying Neem oil + nettle + horsetail. Using Biobizz Bloom, pH 6.5, planning 1 ml per 500 ml water. Is this okay? Any tips? Just experimenting! 🍀❤️

Nutrient or water temps? Water temps between 15⁰C and 20⁰C but usually closer to 15⁰C.Not sure if it's a nutrient deficiency/excess or water temps. Please refer to pics. 2/3 plants are showing light green and yellow tips. New growth seems light in colour as well. pH - 5.9 to 6.1 Daytime temp - 75⁰ to 79⁰ Night temp - 67⁰ to 70⁰ Coco with Gaia Green 444 and 284

Leafs losing Color, die off.I could really use some help recognizing if and which deficiencies the Super Skunk has. It's currently growing in an organic soil that's been pre-fertilized and should be enough to complete the cycle. The temperatures are around 23c (73,4F) day and 19c (66F) night.

Then top leaves of new flowers came in yellow, followed by bottom leaves developing gross pale spots. Not sure why, please refer to my super soil recipe as well as the one feeding I did in week 5.

How can I recover from nutrient lock and bad pH soil. I never pH my water and found out that my runoff is now pH 7.5. I am not able to lower my soil pH.What else can I do to recover from bad pH watering habit and nutrient lock for my two months old photoperiod. Already flushed the plant, has been about 7 days and it still doesn't seem to look promising. 7 days since flushing I watered with compose tea (700ppm / pH 6.0) once.
