It is a magnesium deficiency. So cal mag would be the answer. Unless your ph is off. I see on your diary your ph is not listed. I would start with what is your run off ph. If it's out of range plants can't absorb the nutrients. Causing deficiencies that you might not really have. Around a 6.2 6.3 is ideal. Also if you are using coco coir you will need calmag . Good luck and that should help a lot. Happy growing 🌲🌲🌲👊

I believe It's a slight Potassium (K) deficiency - Yellowing tips and margins with slight chlorosis and mottling/blotching. Increase your Potassium output (usually in high concentrations in "bloom" fertilizers) and lower your Cal-Mag usage to 0.5ml/l max, those are micro-nutrients needed in small amounts and constant feeding of it will cause a toxicity! (Calcium toxicity inhibits Potassium uptake so it might be an option as well). Hope this helps! Good luck and happy growing :)

1/3 plants has leaves that are almost pointing straight up. I have read two opposing things. One being that the plant is actually “happy” soaking in the sun and directing it to the bud sites. The other being some sort of deficiency- either calcium or magnesium? Any thoughts?

Been feeding 10-10-2 bat guano (super grow) and now some 1-9-1 (super bloom) for 3 weeks, still getting brown dead spots on older fan leaves. Maybe still a phosphorous deficiency and plant taking awhile to intake the nutrients?

Please help? All the leaves are getting discolored especially the bottom ones. The upper ones also appear discolored and she looks unwell overall. I gave her a flush on Day 78 and added bloom nutes but 4 days later (Day 81) and I am not seeing any improvements.

Feels like I’ve got all kinds of nutrient deficiency. Which makes me think I’ve got a lockout issue. Do I need to do a second flush with pH adjusted water? How do I help my poor little plant?

Any idea on what nutrient deficiency I'm having? plants are slowing starting to yellow at the tips of the older leaves as well as small yellowish/brownish spots. I think its either potassium or nitrogen. also whats the easiest way to fix? would manure and fertilizer work?

I’ve been using dry nut from Root Organics, I’m curious if I still need to water to run off since I’m in coco. I want to make sure my dry nut don’t get flushed out. Is dry nuts optimal for coco? Do i water the same as others?

The plants are now placed in rows, not on the windowtill but behind & below. This means that they’re: 1. Growing towards the window once again 2. Have parts of them barely exposed to the sunlight. What do I do? Do I let them grow how they want to? Should I trim away some leaves?

Day 4: Leaves have started to brighten and yellow at a fairly alarming rate. With the lower leaves falling off, this looks like a Nitrogen deficiency. Take note of the picture on Day 4 where LSD (the tall plant on the left) is much brighter, and more yellow than Phantom OG (right

I just got my meters in today. Soil pH is reading 7.5-8.0. I wasn't testing the pH of my water until now, reservoir read 8.3, applied pH down to get it to 6.7 and a ppm of 120. The ppm of the runoff for #5 was reading 1500, i flushed it down to 900. Are they locked out of nutes?
