You could try bumping up the ec a little bit. How are the roots looking? I think bacteria can cause the ph to rise. You should use a beneficial bacteria or add a little peroxide once a week or so. They look good for 20 days in veg.

Yes high phosphorus is good for flowering but you don't want it to be too high as too much of it can make your smoke harsh and ruin the flavor. I use athena nutrients which is what the jungle boys use they grow stupid fire weed and this formula has worked best for me compared to other brands...

Do you test your runoff water? You should know if you're overfeeding if the runoff ppm is higher than what you're putting in. It could also be a ph problem. You should add some perlite to your coco too at least 30-40% for early stages. It's easy to overwater with just coco alone.

Looks like a potassium deficiency but most likely caused by the high ph. How much ec or ppm are you feeding? I've heard that underfeeding can cause the ph to rise but idk for sure. I've only dealt with ph going down and that's caused by too much potassium or overfeeding.

4-4-8 is your best bet for flowering. You don't want to neglect calcium, magnesium, sulfur, and micronutrients either but there should still be some in the soil. I only have experience with coco coir hydro and the one time that I grew in soil I never used inorganic fertilizers. You want to have...

I've had two runs in mono tubs that both ended up contaminated with blue mold. I used coco coir as substrate but it was too wet. If I grow again I'd add vermiculite in there to help with the moisture. Just something to consider because getting mold in your house and having it circulate can...

I use athena and don't plan on trying anything else anytime soon. Jungle boys use athena too and the ratios of athena are different than advanced nutrients, general hydro, and pretty much every hydro brand. Athena is specifically for cannabis and most hydro brands just have general ratios that...

You can't overwater in hydroponic coco as long as your root zone is fully established. If you let it dry out too much the ec in the root zone will go up which is what might be causing your problem. Clawing is overfeeding for sure but it's most likely because you're letting it dry out too much...

Nice plants dude. How'd they turn out? Did you get any bud rot or mold from that florida humidity?

My first couple grows was general hydroponics and got good results but not much flavor. Switched to athena and get great results. I mix the fertilizer myself since it's cheaper. If my math is correct this should be the athena flower npk: 2.79–4-8.04 cal 3.4 mag 1 sulfur 3. I forget how much ppm...

It looks ok to me. I've dealt with light leak twice before. The first time I didn't catch it in time and the plant stretched like crazy and grew thin revegged buds but no hermie. Second time it happened I caught it at week 2 and it was fine it just stretched more and some buds fox tailed but...

All I can think of is airborne fungus' or the grow medium but I've tried rockwool with no success so it's gotta be airborne fungus I guess. While I wait for this root powder and fungicide to get here I want to try watering my seedlings with peroxide. Has anyone tried this? My fully grown plants...

I'm doing coco/perlite drain to waste hydro. I've always had bad luck adding seeds straight to coco.

No I'm just dipping them in water every other day. They last 2 days before going dry. When I started them to begin with I soaked the pellets to expand them then I squeezed as much water out as I possibly could so they look moist but there's really not much water in there. The pic I took I just...

Trust me this situation is making me want to never grow anything ever again but these plants have been my main source of income for the last 2 years. I was getting 5 harvests a year almost 6 if I was more on top of my cycles. I've always had minor problems with the seedling stage but never...

I actually tried rockwool cubes and same result. Cubes I got are 4 grams bone dry and 40 grams soaking wet. I let it get down to 20-25 grams and the bottoms of the roots turned brown and soggy. Are seedlings supposed to get all their water from the air? Am I wrong to try to add water my seedlings?

I just dipped the bottoms of these pellets in water & water made its way to the top hopefully that doesn’t kill all my seedlings. Before I watered them I noticed one of them damped off so these are the 11 I have left & even tho they look good I’d bet everything I own they’re gonna die too. I’ll...

I'm gonna order some of that souther ag. What dose do you use for root drench?

I guess I might try the dome after sterilizing my pellets. I'm jealous af I used to grow seeds like that just a few months ago. If my medium was as wet as your's I would 1000% get damp off I guess the only thing different I can try at this point is nuking my pellets with peroxide. I nuked my...

What concentration do you recommend? I also sprayed down my whole tent and fans with 1% peroxide solution. If this keeps happening despite that I swear to god I will buy a damn fume hood just to start seedlings.
