Discoloration of some leaves
SpiritLevelstarted grow question 4 years ago
Hi all, For my question please see the last photos uploaded to my grow. The leaves shown are growing on the bottom of the plants, going from bottom to top, starting from the main stork. Any idea what this is? We’re thinking a deficiency if some sort, potassium or phosphorus maybe

She may have N toxicity from the looks of those dark green leaves that are beginning to yellow and die. Check the pH and ppms of your runoff. I'm guessing your pH is too low and your ppms are too high. In this case do a nice flush. Next best bet is adding some calmag and being sure not to overwater.

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?

Should I reduce N further?Hey everyone, it’s been 11 days now since I noticed a Nitrogen toxicity, and I adjusted feed to 650ppm and notes in ratios according to GHE feedchart (numbers in diary). Just wanted to ask if you all thought they still look like they need less Nitrogen? I could reduce calmag?

Crispy discoloured leaves in flowering, and what to do with them..If you run into issues into flowering that cause your sugar leaves to get crispy and discoloured, do you remove them? Or let them run their course and wait till harvest to trim them away?
