I posted several days ago and I was told to just flush my plant and leave it alone, but the plant is still getting steadily worse. Im not sure what it is, im guessing nute burn, but many of the leaves have a yellowish burnt look.. Also the top leaves look wilted and are very purple and their stems have shrivled up. Its under 4 27w cfl's, i recently put tin foil around my box, dont really think this could cause a problem but I have heard that it could cause hot spots. Please someone help! Thanks!
