I have 4 inch tall plants and it looks like nute burn, on the tips of the plants and I watered them last night with just PHed water until it start dripping out the bottom, today, it looks like the nute burn spots have gotton bigger. Should I flush them now with lots of water to get more or all nutes out to stop the burnin from spreading more? Also, if I do that when should I start giving them nutes again? They are 4 weeks old. I have them in 16oz plastic cups
Thanks!
