That’s fine imo when I’m in week 9 my PPMs are around 1300-1500 so you’re good. Just make sure to feed with pure water between feeding. I’m on a feed,feed,water schedule if that helps. Good luck my friend

Athosanswered grow question 4 years ago

The yellowing at this point is due the plant slowly reaching the end of its cycle, so it's normal. I assume that PPM you mention is of runoff? In soil there is very little point in meassuring runoff PPM; why would you use soil if you are going to flush all it's nutrient out if it? Anyway 3000 PPM Runoff is very little for soil, almost devoid of any nutrient.

Yes that's perfect! If it got that high, you could even go a little lower, say 750ppms.

Heya, During your point in flower I usually run 800-1000ppm in coco. Should be okay! It will let you know if it’s too much by burning the tips of the edges. Cheers

End of Flower, Yellow and crusty leaves ok ?Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves. Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?

Burning Edges/Yellowing and Drooping?The yellowing has gotten worse and I'm noticing slightly burnt tips/edges and some droop. Could this be burn/deficiency or over/underwatering? A combination? Is there anything I can do to fix this early or is it just a matter of giving them some time and less nutrients? Thanks!

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light Soil On my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?
