Hi there Grileon, that's classic Mg deficiency, that's exactly how it looks in a text book. Normally you always want to be adding calmag to the tank. One more thing : i see some N toxicity happening, especially on the plant with the "dark green" 'shiny' leafs. You might want to fix both issues as soon as possible. Hope this helps ! 🚀
KushGANGanswered grow question 3 years ago
Hello agree with Dasboof you have a nitrogen toxicity which the dark shiny green is characteristic. Then for your brown spot it is calmag deficience due to a high EC in your soil. So to correct calmag use epsom salt which is the best way to correct it. You can use it in the soil or in water. More you can mix in water and mist your plant with it for a quicker effect. Good luck. Bye

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?

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.

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).

Defoliation late in flower on Auto'sI like to defoilate, If I were to pick majority of the fan leaves off of these plants being Auto's, will they react or stress too much? I like to defoil near the end of flower to really push all the focus to the budsites. Happy Growing!9 months ago

The lamp was too close(30 cm) for 3 days. I raised it to 50 cm ten days ago, but the symptoms are stil progressing. Is it light burn or potassium deficiency?
