I think you should give @Highlaing the credit for this one... I didn't even think of it.. But when he said it and I saw the fan it was so obvious.

Should I flush? (Overfeeding)I think I have overfed my 2 dwarfs. Theyre showing signs like very stringy skinny new growth and yellow leaf tips. Theyre still growing and I dont want to stunt their growth, so all I want to know is if it is necessary to flush. Please tell me how to flush if so, thank you.5 years ago

Unknown rust on 7th flowering weekThis started as what I thought was a cal/mag deficiency, bought some, gave it for a week at a good dose and 6.3ph, and this intensified and switched from just lower leaves to the upper and a few sugar leaves on one plant. Any ideas? May calmag takes awhile? Or wrong diagnosis?Leaves. Color - Dark-brown

Leaves turning yellow from the bottom upMy older plants leaves are turning yellow from the bottom up. Its probably a nitrogen deficiency I think, I read that its common for plants in late flower but this one just shot its first pistils. What would be the smartest thing to do to combat this? Thx
