    Okay so im pretty new to an indoor grow and have a low budget, basic background info is that i was using an organic soil that seemed to have the right nutrients for it to grow without adding any extra nutrients until i started to switch them to flower, im not expecting a high yield so please don't hate to much on the plants, one of my plants started growing taller than the others so the leaves started curling up, naturally i moved the lights upwards thinking it would stop the burning, now THE NEXT day the top leaves are curling down and yellowing with a little black spots on the tips on some of them, i added some nutrients for blooming thinking that it would be okay and overnight it basically all went to hell, should i use vermiculite mixed with some soil and spread it on top of the current soil to balance the PH ? should i flush my plants completely? i don't know how to flush but here are some pictures of what is going on, PS i have two plants both recieve same treatment, i think i fucked up adding the nutrients

  2. keep in mind my light setup is two 100 watt cfls over each plant along with a long 150 watt light that puts out about 6500k lumens, i was told that the lighting could be used for both flowering and vegging, they are on a 12 12 cycle
     
  3. Looks like a magnesium deficiency!
     
  4. Epsom salt works to fix that.. Add a teaspoon for every gallon.. Also check your ph, should be 6.0-6.5 all else fails you could try a flush!
     
  5. thanks added some Epsom and everything worked out great within the next few days.
     
  6. When in doubt flush it out. Just flush the shit out of it asap with at lease 5 gal of ph water around 6.2
    Dont add anyhting to it can make it worst just flush the shit asap.
     
  7. If you are looking for a very easy to keep track of form of nutrients, i'd try the one that Aerogarden makes. It is cheap and does a great job of not only keeping them from going nitrogen or magnesium deficient, but it also balances out your pH. http://www.aerogarden.com/accessories/1-qt-liquid-...
     
  8. Epsom salt fixed it all? That's good to no.
