started grow question 7y ago
In the final 2 weeks of bloom, when giving no nutrients, should fan leaves show signs of what looks like nutrient deficiency? Not happening on all fan leaves but maybe about 10%

answered grow question 7y ago
Yes, that's the point. For the plant to use its own reserves, pulling them from the leaves

White spots on leaves in week 1 of veg
Should I be worried about the white spots on some leaves? I think it could be chlorine, I let my water sit for atleast 12 hours before adjusting ph and watering/misting. Maybe I should let it sit out longer?

Upside down leaf growth?
What is happening to this plant, it seems to be growing leaves upside down? It had nothing come out for a few days and then 2 new leaves started to grow out of it but it's like the top dark green side of the leaf is growing on the underside. Any ideas on what I should research?

Leaf issues. Lockout? Need to Flush??
Leaf issues started showing up in 2 of 3 plants, progressing fast. Soil runoff tests have been v. high (2000ppm+) so we're assuming it's a lockout issue. We watered 1 day ago, with 200ppm solution so pots are still very wet. Better to let them dry out a bit or flush right away?

Weird Spots on almost every leaf overnight? (Leaf Burn???) My plant developed these spots on the leaves basically overnight...
I was looking after them just yesterday evening and the plant was fine, however I did a mistake. The left plant got completely wet (i had to move it through the rain) and i did not dry it before the light went back on. Right plant is completely fine. No pests (thrips spimis etc.)

Heat stress? Light stress? Nute burn?
Hi y’all Since my girl started to flower the top leaves near bud sites have this weird cupping downwards look. I doubt it might be a nute burn since I already gave her a good flush. I think the heat might be the main issue (86-87degrees during day). What do u think? Day38autoflwr

Leaf Septoria?
Can almost see the end in sight on my first grow, and I think I have a problem. Noticed a few lower leaves weeks back with spots, so I removed them and kept cleaning the bottom of the tent, but I think it’s spreading. Is this bad enough to worry about end result?

Help, please!!!
I need a little help...I didn't have this problem until I added cal mag. So my question is: is this too much cal mag? Not enough? OR...overwatered? My Skywalker OG was doing it as well, but seems to be ok now. Also, does the new growth seem a bit light in color?

Are new skinny leaves normal in flowering?
The new leaves in the tops of my plant are growing out very skinny compared to old leaves. Is this normal or do I have a problem on my hands? Also, some holes in leaves but no bugs under scope. I just started weaning to flower nutes. Feeding 1/2 strength nutes, 3rd feed of grow
