Wow, great image! Thanks! I need a poster of that on my wall! haha According to your image, Im definitely leaning towards phosphorus deficiency but the problem is they are being fed by the same rez as my healthy girls... any suggestions on a fix?

Using Flood table with 25gal rez. Girls are in small rockwool cubes in hydroton Using GH Duo, PPM around 900, PH 5.9, around 6 weeks into veg. These two girls have the same brown spots forming and the plants look altogether unhealthy. The other girls look great and are sharing the same rez...

Anyone? the problem has gotten worse since I first posted, new leaves around flowers are cupping in. My light is about 12" away could it be heat stress?

Im almost 2 weeks into flowering and all the new leaves around the flowers are starting to cup downward. They are in 6" RW on hydroton on a flood table with 1000W HPS, GH Duo. Im currently flushing with clean after I started getting a lot of yellowing on fan leaves and more N didnt help. They...

Yes, Excellent link! The Dr. I got my rec. from offered just this, a 'cultivators license' for up to 99 plants for $420 (cash), Im so glad I didn't get it! lol

Im afraid to lift the cubes out because im not sure if they have rooted into the pellets yet... I also added a layer of pellets on top of the cubes because I heard you should not let the rockwool get exposed to the light is this true? I will definitely look into son Superthrive, Thanks...

Hello, About 10 days ago on my first attemt at a hydro system, using 6" rockwool in mesh pots on a layer of clay pellets, I over watered the rockwool thinking I was suppose to water them twice a day for 15min each! I know I know, misinformed, plus I think the rockwool actually submerged in the...

Thank you everyone for your input!! I think Im focusing too much on all the small stuff, like Japanfreak suggested, Im going to continue my current grow with tap and see how it goes. Ill just have to keep a close eye, make sure they don't get chem. burn... So far Im off to a bad start after a...

Damn that Sour D is lookin Great! Keep up the good work! +rep

I'm no expert, but my attorney claims if you are operating as a legal state collective or co-op you can grow for your patients as long as you have a written agreement from the patient(s) followed by the state guidelines for collectives/coops... so being a caregiver is not necessary. But if...

Great Info imagreenwitya! I would also read the Attorney Generals "Guidelines of the Security and Non-diversion of Marijuana Grown for Medical Use" (google it) This will give you a standard to follow when creating the document needed to grow another patients plants.

I have read a lot of posts about Tap water PPM and I get conflicting information...:? I use tap water in SoCal and after I let it sit overnight or even 48hours my PPM is around 600-650! (its about the same before I let it sit as well). Is this bad? Do I really need R.O.? Im currently 1 1/2...

Wow, this information is golden, I think Im definitely overwatering my rockwool, which would explain the drooping leaves. Just like you said, I made the newb mistake of overwatering in fear of killing my plants from underwatering lol. It is hard to determine if the rockwool is damp or not...

Great! thanks for the info! I was wondering if they would get plugged up, but I guess its worth it if it adds oxygen to the water, im totally going to go pick one up today. Im guessing they are cheaper at a pet store vs. the hydro shop..?

Nice! Here in Cali I get between 7-7.5 after sitting overnight, have to add down every time. I aim for 5.8

Hello, I am new to hydro, Im currently running a 3x6' table 1000w light on 4' track with 12 plants and a 25gal res. with Gen. Hydro a+b... My questions is, should I add an air stone to my res? I was going to pick one up but I hear conflicting information from friends, some say it isn't...

Haha, this is my first Hydro grow... I have my light on 24/0 I heard this helps veg more vigourous..? also, I heard that drooping leaves was a sign of underwatering, but I know overwatering has the same affect, should I stop flooding for a day to let the medium drain out some of the water or...

This is my first medical hydro attempt and I am determined... They were bare root clones i transplanted (almost 5 days ago) into pre-soaked plugs and put them in 6" grodan cubes. As instructed by my local hydroponic dealer, I soaked and rinsed the 6" cubes with 5.5, put them in pots on a bed of...
