Yes, I've read the thousands of comments, threads, and everything else where people have mentioned these words. Can somebody just tell me, while looking into LED lights, what are the recommended requirements for a plant in regards to PAR, lumens, and lux? Per square meter? Per square feet? I...

I've been using Fox Farm 3-part and CalMag for many years in my DWC system. Are there any simpler nute combos? Thanks.

Hey guys, I just got questioned on my nute selection because I use DWC. I use Fox Farms' 3-part... Grow Big, Big Bloom, and Tiger Bloom. I've been doing this for years... is there something I don't know? What do you guys use? Thanks ahead of time.

Running a DWC system with 4 buckets, 400w HPS, Fox Farm nutes, 2 weeks into flowering after 5 weeks of veg, pH 5.8 and ppm 575. Had early problems with rust patches, got CalMag, but nothing seems to work. Now I have yellowing leaves, rusting on outer edges of leaves, leaves with rust in the...

I realized my main problems with my system is that the circulation from the reservoir to the 4 buckets is slow, and by the time I need to add anything, whether it's adjusting pH or adding nutes, I would need to directly add it to each bucket rather than into the reservoir. I was going to add a...

Hey guys, What are my plants trying to tell me when I feed them 475 ppm, then after a week drinking that water, it goes down to 280 ppm? Does this mean they want more nutrients? So up the ppm the next time I feed? This is in a DWC system. Thanks.

Hey there. Recently I posted a pic of some type of burn or deficiency (below). I am in 5th week of veg, and they are about 2 feet tall. When this happened last time around week 3, I dropped the TDS from 450 to 300. It helped, but didn't fix the problem. After two more weeks it is now...

Ok, here's the rundown. About 4 weeks in, ppm are roughly 400, pH is around 6, 400w MH, 4 pod DWC central reservoir, 3 part Fox Farm nutes, using Grow Big and Big Bloom for veg, and just added some CalMag to fix a problem for one of them, could the CalMag be causing this? Or something else...

I'm 3-4 weeks in from seed... 5 plants, 1 is struggling. 3 started with brown spots starting on the outer corners of the lower most leaves... I checked the pH, and dropped it from 7.8 to 6.0. This seems to have fixed the problem for most of them, except one. This one is growing unbelievably...

I have the HM TDS meter; and it just read 238 x10... is this 2380 ppm, or is this 1238 ppm? I don't need math lessons... I just want to make sure what my plants are at. If you're a smart ass, just move on. (I'm using 3 part Fox Farm and I'm about 5 weeks into flowering. Please let me know...

Hi everybody! I'm about to trim some cuttings to put in a misting cloner, but I was wondering what nutes to put in the cloner's water. I'm using 3-part Fox Farm nutes for my other systems, so I was thinking .5 tsp/gal of each Grow Big and Big Bloom. I would continue to use this until fully...

I switched into flowering about 4 days ago. Yesterday my iPower 400w digital ballast fried. I have ordered another but won't be here until Monday. I was going to buy a bunch of CFLs to hold me over, but stumbled upon a 250w halogen worklight, it said about 9000 lumens and 2900K spectrum...

Been vegging for 6 weeks, just switched to flowering. Monsters! How they looking?

I'm experienced with hydro, but have a little plant sitting on my deck in a pot that gets very little attention, and a little amount of light. Compared to the hydro, this plant is obviously stunted in growth, but still growing. I was going to start a mother plant, but wanted the strain from...
