I second this. Your gravel is probably the culprit. Gravel doesn't sound like a very good medium anyway.

I thought about that that the gravel may be the problem but for me to get another medium here on the island is very difficult but the gravel I can use it again an again just wash it and it ready again and i having good results from my plant I just wanted to see if I will get better result if the PH was stable

What island? Can I come and hang out?

that doesnt look like normal gravel. it looks to be more mineral. be carefull.

My first grow was in pea stone gravel and had no problems, that stuff you have looks quite different, I agree with superstoner looks more mineral, could it be lime stone?

Giligans island? I'd bang ginger and mary
ann...say hi to the skipper for me

Looks like ground up lime stone, this would cause huge ph swings
