In most cases, this is a calmag issue. Either she's not getting enough or the pH is off so she can't take it in. Either way, easy fix! Looks great!!

If it starts from the bottom up it’s a calcium deficiency, if it starts from the top she needs more water! ( from my experience of course) hope this helps friend & happy growing!✌️🏼🌱

Big difference in first true leaves' size
Big 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.

Plant starting to yellow too fast
The crystal meth has started going yellow very fast. The buds still have at least 2 weeks of growth needed to fatten out and pack the trichomes with thc.. I know it is normal to start dying but isn't this a bit early? Should I let her keep going as long as sugar leaves are alive?

Hanging leaves (first couple)
Das erste Blattpaar hängt leicht runter und sieht nicht fit aus. Liegt es an der Entfernung der Lampe? Gegossen habe ich 40ml jeden zweiten Tag nur als die Erde komplett trocken war bis 3cm tief. Luftfeuchtigkeit habe ich bei 65-80%. Bitte um Hilfe.:)

Too little calcium in early flower?
I’m in the early weeks of flower and am seeing this happening. I thought it was due to an attempt at foliar feeding, but those initial problem leaves have been trimmed. Is this a calcium deficiency, and if so, how can I address it? (NLS top dress/coconut powder/recharge)
