latitude54 Posted March 30, 2023 Share Posted March 30, 2023 Strain: Godfather Grow type: seed Age: day 27 of flower Medium: Clover Light: 600w HPS Temp: 25-28ºc RH: 40% Watering schedule: 2L every other day Nutes: Intense Bloom Adjustments: 1/4 tsp epsom salts in each feed I have 4 plants in a scrog and one of them has been noticeably smaller than the rest for some time. I noticed last night that this smaller plant is showing signs of a deficiency which (searching online) looks to be a nitrogen deficiency. It seems odd that it's only this plant that has this issue and the other 3 seem happy and healthy. That being said, they were all grown from seed so there's a good chance of different phenos playing a part. The only other thing to mention is that this plant sits in front of the fan that's circulating air below the canopy. Link to comment Share on other sites More sharing options...
MindSoup Posted March 30, 2023 Share Posted March 30, 2023 Which leaves started going south first? Top leaves, bottom leaves or leaves closest to the fan? 2 Link to comment Share on other sites More sharing options...

Top leaves, bottom leaves or leaves closest to the fan? Bottom leaves but not necessarily just the ones closest to the fan. The one in the picture was plucked from the middle of the scrog net. 1 hour ago, Shumroom said: Could be low temp at that spot, can you point the fan away from it a wee bit? It's a bit difficult as its right in a corner and oscolates. I can certainly turn the fan down though or just stop it oscillating. 1 hour ago, RUFUS HOUND said: I was gonna say mg def what with the red leaf stalk and yellowing between veins but i see your already giving epsom. My epsom salt calculation and delivery is far from scientific. So it could be that I'm slightly under for what this plant needs?

MindSoup Posted March 30, 2023 Share Posted March 30, 2023 If it's a thick canopy then you can expect some of the shaded leaves to due off naturally as there's no point the plant keeping them alive. 1 Link to comment Share on other sites More sharing options...

ratdog Posted March 30, 2023 Share Posted March 30, 2023 (edited) should have taken a whole plant shot while you were at it looks more like light bleaching than anything else, are all the leaves at the top of the canopy like it? have they been like that for long, and is it spreading? i don't think it has much to do with calcium doesn't look like N def either are root temps stable too?

Military Grade Posted March 30, 2023 Share Posted March 30, 2023 Maybe 1/8th of a tea spoon per litre is not enough. I do about quarter of a (slightly larger plastic) tea spoon with mine (Everyones mileage may vary tho) 1 Link to comment Share on other sites More sharing options...
