Yellow/Brown spots
willie72started grow question 3 years ago
My week old RQS Haze has developed yellow spots on its leaves. The info for nutes is in my grow diary. They started to become visible yesterday & were more pronounced this morning, this afternoon they appeared more developed.
PH dropped to 4.8 2 days ago but sorted quickly to 5.8

Thanks fella, the bucket is getting changed tomorrow. I'm currently running an air stone in the water I'm going to use to dechlorinate it.
The bucket was set up on 24th of May so due a change.

I also use GH nutes and DWC buckets. For me, this looks like you haven't done a full res change since you started. You need to change the res completely at least every 2 weeks (although 10 days is probably better).
Other possibilities include not using any calmag. This is 100% necessary if using RO/distilled water. You can't get around it. CALiMAGic from GH works very well!
I also use Diamond Nectar for the entire grow and strongly recommend Floralicious Plus for flower.
DM me if you have issues, as I have experienced and solved a whole slew of problems with your setup.

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?

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?

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

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?

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.
