I have symptoms of both N deficiency AND toxicity....
Kaya666started grow question 6 years ago
I have symptoms of both N deficiency AND toxicity. Paleness is spreading up from the lower leaves, but there's also downward clawing & "burnt" tips on other leaves. Plus some weird brown ends on the larger fans. Haven't fed any bottled nutes. Halp?

Hey Kaya, you have all sorts of symptoms happening at the same time because of PH fluctuations probably due to the Kelp and a bit too much P in the urine causing a bit of lock out perhaps. The main thing is controlling the PH - maybe buy a PH strip it's very cheap ! Kelp will raise your PH quite a bit that's why you want to PH down it. Good luck with the flowering man ! 🚀

Definitely not a healthy looking plant, showed some signs of nitrogen deficiency in the vegging phase and also some toxicity in the flowering stage. Try and keep your PH balanced between 5.7 and 6.5 if you are using a soilless growing medium. It will make the world's difference. Good luck man!

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).
