AsNoriuanswered grow question 3 years ago Your plant is super healthy !!! Lanky, but healthy !!!
Forget all nonsense that you know or heard, just grow plant, use less nutes, it always works better than more !!!
Flushing is last resort and usually bad, plant stops drinking and people drawn him even more ... Highway to all problems.
If you think you overfed or see light symptoms - just slow down, give two three pure water waterings and all will be good.
Less is more ! Golden rule !!!
All the Best !
