Long battle with deficiencies.
Flashback25started grow question 3 years ago
For a week i have been fighting deficiencies , the ph seems fine. Part of the problem was fixed by calmag but how it seems to be something else, maybe someone can help me identify.mid to top leaves affected. Also overall heat could be a problem (as temps outside rise)

Tend to agree with @DrCris here...looks like light issues...the "Praying" leaves would imply light is a bit too high for them and the fact you're seeing it in the upper levels would imply that. Don't forget too, damage done from any Ca/Mg issues where there are now yellow spots will not reverse, them cells are dead...Raise your light a bit and it should be grand.

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?

Yellowing on older fan leafHey guys, my photo sour d has some earlier growth showing some yellowing in the center of a few leaves. I fed this plant a foliar spray of cal mag plus way back in the 2nd or 3rd week and it got burned on the leaves but does this look more like a deficiency?

Day 4, after emerging. Is this coloration on the cotyledons okay?Humidity is 55 - 70, temp is around 20-24c, 50w full spec led
It's my first time, and i think i have been watering it too much
I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?

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 white

Help: potential over fertilisation or over waterningI used Biobizz bio grow, 2ml/L and sprayed them more than usual. The tip of the leaves is getting yellow. 2 plants have the leaves pointing down and seem more textured and tick. The other 2 (the biggest) seem better, but the yellowing of the leaves is more evident.
