Also, I forgot to add that a gradual change in ph is better than flushing with ph'd water. An instant change like that to the ph with an already sick plant could end badly. Although, you are into flowering pretty far and you should be ok by getting the PH down to 7 immediately with a flush.

Thats a huge relief... thanks.

I would transplant into a 3 gal. container with fresh, moist soil. That browning should subside. When the plants are young the roots like moisture. You are under-watering and that dixie cup you using shoulda been discarded after day 10. Definitely transplant and water evry 3 days instead of 6...

I have 2 x 600 HPS over plants 40 days into flower. I just got home from work and noticed one of the hps was still on. The timer was switched to 'On' instead of 'Timer':cuss:. The light stayed on 9 hrs. into the normal dark cycle. So, is this going to totally 'F' my grow??? I never had this...

Wow! How long did it take you to reach 5 ft vegging? What size containers you use?

Dutch Passion's Blueberry are at day 30 veg. When should I top these? They are currently 18/6 under 6 t5's. I usually grow strains in 2's. Maybe I should top one..., anyways, I'd love some feedback. Thanks Nirvana's Blackberry x2. 12/12 under 2 x 600w HPS. Planted seed August 2...

So, essentially the soap acts as a poison by dehydrating their membrane... thanks, even though I didn't ask how the soap poisons them. Probably because I already knew and didn't think it was important, but thumbs up for the clarification.

Ok I got you now. Hydrogen peroxide mixed with water kills almost all of the adults and larvae. Along with all the other organics. This has helped me reduce major gnat probs, but once you are infested I have heard it is nearly impossible to rid 100%. Best way I know of is to make a completely...

I do not use MG, BUT I have used it before. As long as it gets flushed in the end there is no difference between FF and MG. I have been growing for 6-7 yrs and the only time I had a problem with MG was in the early days before I had an EC meter. Good luck with it!

If you post a pic I could help out...

It could be all of these things, but I wouldn't tell him to water and give nutes without further details about his grow. You can't definitively say that it is without-a-doubt lack of nutes and water; atleast, not without further description or pics of the problem.

Yes, I vegged with a HPS this time to try out. The 2 600 watt HPS got me sprouts in 7 days with waaaay too much electric expense. 6 T5's got me sprouts in 3 with far less electric expense. As far as foliage growth and veg. time. 4 weeks under the t5's and 6 under the HPS to get to 18 inches...

I peel the cotyledons as soon as they start to curl up and wither. I usually clip the lower leaves throughout the vegetative stage or if leaves are hindering further growth up top I will clip them too. It promotes new growth by opening up more breathing space and light for the younger branches...

Need pics to be certain, but it sounds like you need more light or less water or maybe both. What are you're temps????

Also, if you have fans blowing over the plants the gnats can't fly as much; therefore, they have less opportunity to mate.

I have always used a wide-bowl with some water and dishsoap in it. They love the water and then die from poisoning in the water so dead bugs aren't all over the place. Don't Lady Bugs eat foliage?

You can buy tightvac sets of 4 for $20-$30. The set can hold about a half lb. I use these with meds bagged inside and then store in the fridge. Nothing gets in and nothing gets out. I got black ones, but here's a pic.

I was looking to buy this to save some of the hassles involved with tanks and homemade generators. Seems cool, but hopefully I can get some answers about it from someone who has actually used it opposed to selling it lol. Does anyone have any experiences with it? Would you also know the...
