Whats going on here with these burnt leaves?
Robertsanswered grow question 3 years ago
Looks like a deficiency of the cal mag variety. Would check run off ph first. If that is in a acceptable range then it needs more nutrition. If growing in coco you always need cal mag in nutrition. Good luck and happy growing
Organomananswered grow question 3 years ago
Slight burning due to excess fertilizer strength and a slight touch of cal/mag deficiency.
Half strength nutrients are usually more than adequate.
Remember too, it is very easy to fix a slight under feeding, but very, very hard to rescue a burnt, over fed plant.
Hope this helps, Organoman.

Hi there, Deficiency sometimes doesn’t result from lack of nutrient.It may lockout due to improper pH or abundant of other nutrient in that pH.Find out the base cause. As long as you are giving the perfect growing conditions and feeding, they will not go worse.Before you do anything, make sure your water pH, ppm(EC) and run off are in corrected range.Since you are growing in mainly coco medium, keep your pH around 6.0 for both in and out.Always make sure there is enough water run off from the bottom to prevent nutrient accumulating in your medium.Also check both ppm in and out and compare how much they are different.Good luck and happy growing... ✌️

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).

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.
