[quote=SeaTownMangler]Sorry for the lame question but i have spent hours and am just more confused than ever. I have a friend with a 14 gal rubbermaid (1) with 5 plants. Setup one week ago and left unattended untill now......(unexpected clones one day before trip!!!) Using GH 3-2-1 mixed up 10 gal worth in 12 gal of water (not ro) used tap 15 years ago w/ no probs!...but anyway the light is 430w agrolux hps heres problems:

Leaves(lower) turning Completely yellow (not just tips) and am confused as to whether this is a N deficiency or a burn (2 totally different remedies!)

1st off. using 3-2-1 formula is 3 times the recommended amount of nitrogen. so think about your nitrogen Q? you might be frying thoses young plants with too much nutes!

Flush immediately and replace with the following:

don't be fancy. be safe...use 1-1-1 for veg at 5ml (5-5-5)per gallon each. then in flower use 8ml per gallon each, or there are many formulas , but most are theory. the manufacturer direction's work as well as any recipe.

I use per gallon in ml...5-5-5 for veg, and I use 4-8-12 in flower. I vary these and use additives, but you should stay simple because 3-part is all you need along with a little calmag, b-vitamins. goodluck

ph should be around 5.8...6.2 is too high, latewood:smokin:
