I am growing 12/12 from seed using GH nutes. I am wondering whether I should start seeds with a 3-2-1 grow formula and switch later to a 3-2-1 bloom formula. Also, what would be good PPM readings from from seedling to mature plant? Thanks

I am running ebb&flow using GH nutes, PH around 5.8. Each reservoir gets about 1/2 ounce of hydrogen peroxide every day. GH nutes have PPM's from 500 (seedlings) to about 1400 (full flowering). I am running 12/12 from seed and it has been working well. Lately I have seen yellow spots...

I am running ebb&flow using GH nutes, PH around 5.8. I am running 12/12 from seed and it has been working well. Lately I have seen yellow spots appearing on leaves and am wondering what it might be. I have looked at the various plant problem guide and haven't found the solution. I was...

Just doing my first 12/12 from seed and was wondering why couldn't I also FIM the plants. Anybody have any thoughts?

Yes I am using the Flora Series. As to running 300 ppm with seedlings, they seem to be doing well.

I am trying 12/12 grow for the first time. Going well so far. I am watering 4 times in the 12 hour on period. Is that too much, too little or OK? I am running GH nutes, equal proportion of Grow, Flower and Micro. Does that seem good? I am running ebb&flow with PPM numbers of 300ppm for...

They are under flouros and PH is 5.5-6

I have been having this problem lately. Growing ebb&flow using well water with TDS of about 75ppm, no nutes yet. Seeds sprout and grow about 1 inch high and then the leaves start to yellow and wither. I am lost. Check the pics and help me out.

I am adding nutes to the seedlings. They didn't really need them but I am trying to find source of problem.

I am at a total loss. Let me explain. Been growing for several years, using ebb & flow Bagseed growing in rockwool Well water that is about 75 PPM GH nutes taking water to about 250PPM PH around 6-6.5 Fouros for 18 hours a day 1 watering (30 minutes) every day OK, seeds sprout and start to...

I am running ebb and flow. watering 4 times a day. My seedlings are dying and when I pull them out I notice that the rockwool is sopping wet. Am I watering too much? Thanks

Something is not working. Running ebb&flow with water that is 50ppm on meter. Planting bagseed. Nutes added in small amounts yielding ppm of 275 (with water). Ph is around 6 and the lighting is 125 watt CFL about 12 inches above plants. Many sprouts but sprout leaves begin to curl and die...

I am using Gen Hydro 3-2-1 nutes. I typically take a half gallon of water and add nutes in proportion - sometime making a stronger mix and sometimes making a weaker mix - depends on how much a I need. If I mix it too strong and don't use it quickly it will precipitate solids out into the jug...

In response - I have had many grows, only lately has this problem occurred. Most of the plants are affected. The strains are mixed, the medium is rockwool. PPM of nutes is 500-900 (base water is about 150). Temps are 80 or less.

Having problems here - grow is indoor hydro (ebb and flow) under a mix of flouro and HPS. Has been working well until lately. Using GH nutrients with 3-2-1 ratio. PH is around 5.7, checked by meter, ph strips, and aquarium ph test solution. What is happening is as follows: Plants germinate...
