Hey guys, first indoor grow, 4 1/2 weeks in to flower, feminized blueberry, 3 are flowering snowy white and 1is dull white or yellowish, and the flowers are smaller in size but the quantity are good and all 4 look health. Is it a different strain or something else? (Back left and 2nd top view)



I would raise ph going in to 6.5 to 6.8. But iwould be happy if were my plants
Did a flush this morning with water pH at 6.8. Runoff pH was 6.05,
PPM was 610. Hopefully I’m on the right track
Good to hear. Let's see how they do this upcoming week
Looks a lot like symptoms of nitrogen toxicity. Are you in soil or coco coir? Do you know the pH and PPM of the runoff?
Soil, FFOF, 575/1340. the others are in the same range for both pH and PPM.
Is that supposed to be 5.75 pH and 1340 PPM?
Yes
your ph is out of range imo specially since you are in flower . i also see signs of nitrogen toxicity
They are due for a watering today . time to flush??
You mention one plant has smaller buds, although, that can be normal since they are different cultivars. If they have stunted in growth I'd say yes flush. 1340 PPM isn't extremely high though; that's normal for weeks 4 and beyond in flowering. If you don't end up flushing, you can certainly just give the plant plain water only for several weeks until the leaves lighten in color. Hopefully the bud structure won't be impacted. Honestly having nitrogen toxicity in flowering is one of the worse times to have it 😕
What is the best way to raise the pH?
Thanks guys, I appreciate all the help
also another way to raise PH if the watering has no effect is to top dress with dolomitic lime . this also provides you with cal/mag . as for the quantity i use 15-20g for a 15lt pot . try mixing it in the top soil and water after.
