It is just Miracle Grow, I was feeding every watering, like every 3 days, with quarter strength, of 15-30-15, my ph is at 7.5 ish, it is heartbreaking seeing all my girls slowly die.

don't worry, you made some mistakes but you will learn and your next grows will be better.

MG is not good for growing. It probably has time release ferts which are bad for the plants. If this is the case, DO NOT FLUSH. I'd stop feeding all together. Also, adjust the pH of your water to 6.5, and use a good meter, not the soil probe. If you are sure that the soil doesn't have time release nutes then flush it well, and start feeding again.

instead of using nutes to fertilize, make some compost tea for your plants. read about it - aerated compost tea. it will do wonders.

also - i'm not sure but it could be that your pot is too small for your plants. in this case there's not much to do now but for the next grow you want to keep a better pot to plant ratio in terms of size.

Ph is off, happens way more often than burn and is the same thing as underfeeding. Get your ph right. Also, the lower leaves might not be photosynthesizing because cfl's short range of light. Dont use miracle grow. Its bad. Most of the nitrogen comes from piss, always throws the ph off.

yes but don't be extreme about it, better to do it gradually. then again, I never had much luck lowering soil pH, especially with hard water like yours that's hard to lower. If possible, get some distilled/filtered or even mineral water.

Alright Mate, im not getting involved trying to resolve this issue with the nute's (looks a bit like nitrogen deficancy, i would flush out normally but you are using miracle grow and that will escalate the problem due to the slow release nute), but for that ammount of cfls you could run a lot better system, 2000 watts of cfl's is no good for anybody especially you and especially when they should be 6500k in growth and 2700k in flower.

Your gonna have sort them light out buddy.

Happy growing and sorry about the spelling.

Whichever way you spin it your using 2000 watts of cfl's, for the same amount of electric you could run 2 1000 watt hps and get a lot more saturation on those ladies.

Like i said mate, your growing in MG which unfortunately have slow release nutes so the more you water the more nutes you are releasing in to the root system, if you had used proper soil you would flush them out (put three to four times the amount of water the pot can hold, through it) it is like pressing the reset button and starting again as it wash's all the salt's and shite off the roots. In your case i am not sure how you would go about doing this, get your ph levels right and give it a week on just non clorinated water, if that doesnt sort it try uping the amount of nitrogen they are getting but dont forget to cut the nitro out when you start to flower.

Sorry about the spelling.

Same here coco all the way. Some people mix it with other stuff but i find using plain old coco is the best. What is in your resivour is what the plants get. Much easier to control with and when the plant gets nutes and supplements.
