PPM run off higher than Solution PPM (Soil)
MisterSixstarted grow question 4 years ago
Nutrient solution at 550 ppm - 6.2 PH, I water the plant and get 15% run off which read 1500 ppm - 5.9 PH.
My plant still look healthy no sign of deficiency or toxic problem.
It's the TDS in soil still remand or salt build up this case.
Should i flush her next turn.

As Harbinger already said: this dark green does not look healthy.. that's a very high dosage of nitrogen, and if you say the run-off is 1500 ppm (i believe you take the Hanna scale), it means an EC of 3.0 which is way too high for most plants.. especially at this size. I suggest reading this: https://www.mandalaseeds.com/Guides/Fertilizing-Smart-Guide
30.9 degrees is also too hot, so try to get the temperature down, and preferably the humidity up (60 to 70%)

Your plant looks nitrogen toxic to an extreme.

I Believe that with the pot size that big there should be nutrients on the soil still and you won't need to add that much at this point.
So it could be nutes from the soil coming out and some build up too

expert opinion asked ? Maturity in day 49 flower from 60-65 (according to breeder)Maturity in day 49 flower from 60-65 (according to breeder)
I'm not sure about the degree of ripeness.
I used Co2 for a few weeks (1000ppm), the grower says ~60-70 days of flowering, so I would be missing 10-20 days, but they look quite ripe ?
What should I do
Thank you

Feeding right after repotting (coco coir).After repotting an auto flowering plant I get runoff EC of 800, while feeding water has EC 1200.
I guess EC gets diluted (biggest part of coco coir is new).
Should I increase EC of the feeding water?
I see slower growth but it may as well be due to stress of repotting.Setup. Strain - Autoflowering

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.

Questions about wateringI created a 40 ml solution, the instructions say to transplant after the sprout has grown to the top of the plastic cover and the roots are visible through the plug. The question is, is 40 ml of liquid enough for this growth? I think not.

Beginning of Week 2 - Yellowing? Over/UnderFeeding?Are these first leaves showing some yellowing or is this a normal shade for leaves at this point. Just wondering if I might have overfed the plants, or even the opposite. If anyone was able to share what they think it would be extremely appreciated.
