Mites, root rot, or light intensity
StarPlatinumstarted grow question 4y ago
Does anyone know about tiny yellow dots on new developing leaves are a sign of in early veg? Im growing in RDWC so I didn’t think mites would be an issue. I did notice one relatively brownish root as well, but the rest were all white and healthy. what should I do?

Dont think its a pest. I bet you its a ph problem. Watch your PPM and PH and everthing should return to normal. It wouldn't hurt to remove that foil as well, air circulation is very important. You may end up with mold if air cant get to the roots, I would also invest in Beneficial Bacteria to fend off root rot. I have been growing DWC for the last 10+ years, you have everything in the right spot just missing something to keep those roots healthy white in my opinon. Also you were right about lowering nute levels with dwc at least thats what I have been used to using RO water. I hope you get everything straightened out!👊

looks kinda like a mag deficiency, yellowing of edges on lower leaves + sad plants.
maybe root problems too. Both effect leaf turgor.
80f/40% humidity isn't a great VPD for veg, so that will exasperate any problems u have because it forces the plant to drink more.
If you can get the humidity higher, 55-60%+ would be a lot better, or lower ur temps.
So most likely just a PH issue, like thundrfuk said, maybe the VPD or root problerms making it worse.
good luck.

I looked at the diary to understand, you reduced the nutrients when you shouldn't have, the problems are there because they're hungry. Remove the aluminum you put in, it doesn't help with the light issues, in fact, it takes oxygen away from the roots. As for the seedling, it's possible that it's not getting enough light, which is why it has lighter parts along with the lack of nutrients... so go back to normal fertilization and the color will return...

Hello all, I am having some issues with my outdoor grow. It seems the leaves are beginning to turn yellow. It has not received nutrients I’d say in about a month. The main reason for asking is because I do not want to over correct by adding nutrients if that may not be an issue.

Nutrient burn?Hello I have one plant with yellowing leaves that are also curling downward. Only one plant of 6 has this problem, I suspect maybe this one is just sensitive to the nutrient rich soil? I am using fox farm happy frog and have added no other fertilizer. What to do, flush all?

Yellow leavesHi guys, unfortunately because of an emergency I had to leave my 2 babys with some friends for three weeks. At the bottom some yellow leaves and like burning signs. I don't think it's because of over nutrition. They didn't get any for three weeks. Might be not enough nutrient?
