I'm new to this whole planted tank thing as well...and my plants look the same as yours. I used the blasting grit as a substrate and buried some tabs. I have dosed twice in 2 weeks with Flourish but my LED strips are pretty cheap and with a 22" high tank, I know I'm flirting with disaster. My plants look about the same as yours...melting and some brown algae on them. I find that responses here aren't always fast in coming. I posted something similar to your post yesterday and no responses as of this morning. But I have read up a lot on the whole low tech thing and it seems that there is often an adjustment period complete with a little algae and melt and what not. I'm counting on the fact that that is all it is. I scrutinized my plants this morning and despite my less than ideal conditions, I noticed new growth...not just on the wisteria but also on one grass like plant (no clue what it is) as well as my Anacharis. I have another plant that had new growth a few days ago but my Acara (that my daughter named 'Milo') is a greedy little bugger and keeps munching on it. So don't stress just yet. It seems as though it takes a few weeks for the plants to acclimate and put out signs of new growth. So if no one responds to us with a personalized approach to how we can improve our individual tanks, we still have the option of waiting and trusting that life has a way of prevailing and that our plants will come around. Keeping my fingers crossed for both of us!
