Burn or deficiency?
Jellystarted grow question 2 years ago
Organic living soil, top dressed once w guano and vermiculite at start of flower. Last week fed with molasses and now have some yellowing on the upper leaves, some brown spots on top leaves, and red stems on one. No bottled nutes. Burn or deficiency?

Deficiencies... calcium and potassium .. and I think phosphorus is headed your way as well... If you're not doing bottled nutes, look into bone meal and Langbeinite for your P and K ... I've used Langbeinite 0-0-22 before but it doesn't dissolve easily so I used one tablespoon as a top dress once a month throughout the grow...
Good luck!

it seems to me that you started having problems after the flora started, you can see that it's not an excess of nutrients because it was losing color until it started to burn, and you didn't exaggerate in anything from what I think, some very clear signs of lack of calcium are those "burned" balls, unfortunately I don't have much knowledge in organic, but you will need to do a better coverage when you get into the flora, guano alone will not guarantee a good coverage

Late flower issues- chop early?Week 8 of flower (haven't been best at keeping up with diary). Poor girl is deteriorating rapidly but I don't know why. Too late to fix, but too early for ideal harvest. Should I just let her ride or chop early and try to salvage what I can?a year ago

Should I harvest in 2-3 weeks ?Hey, do you think my plants might be ready in two weeks ? They're autos in 7th week of their life. I know that 9 weeks is ok for most, but these should take approx. 11 weeks. Do you think one more week of feeding, then flush would be appropriate ? Trichomes are mostly milky whiteBuds. Other

Calcium Deficiency???So this is a Calcium Deficiency right? Noticing on top leaves. Not bad yet but want to stop it before it starts as this grow has been my best so far.
