Foxfarm says it helps with salt buildup. I don't know if it does. Might be a good investment if you have a salt buildup issue. Looks like it could also help with other issues also.

Nutrient deficiency? If yes, what's the best course of action to salvage the situation?
First time grower of 3 autos, at week 8, lower leaves started turning yellow, top leaves started to get smaller/develop brown spots 2 weeks ago. Is this a nutrient deficiency problem? Soil should have been fertilized for 3 months, but I'm thinking they burned through it.

Low PH runoff, dealing with deficiency due to low soil PH. Added lime and PH went from 5.4 to 5.0 after watering. How to raise it safely and quickly?
I have been dealing with a nutrient deficiency so added nutrients.It looked ok but then got a bit worse and I took some runoff readings which were 5.4 and then 5.0 the next week after adding lime to raise soil PH. How can I best raise the soil Ph being that I added lime already.

Yellowing of plant
The plant on the right side is starting to turn really light green. (Not yellow yet.) It seems very uniform, started from the top. Does this look like a sulfur deficiency? Or more like a calmag problem? The last picture it looks really yellow but this is just the lighting

PH measuring for Organic Growers
If I’m growing organically, do I measure my PH still? I heard that the PH up & down liquid isn’t organic & that organic growers should throw away there PH meter because the soil will adjust to what ever PH level I water them with. Is this true? I’m having a cal/mag deficiency.

Yellow tint on new growth
I've spotted some yellowing on new growth. I'm just in the end of Week 3 and am thinking it's caused by nutrient deficiencies? I've been sticking to 0.25ml/L and am planning to go to 1ml/L starting Week 4. Does anyone have any other ideas?

pH very low (5.0) but plants seem to appreciate it!!
The pH of the reservoir is lower than the perfect range (5.0) during flowering stage for almost 2 weeks but plants don't seem to suffer. They are growing very fast. Should I change it or leave it if they seem good?

Nitrogen Defficiency?
I’m growing with super soil and amendments for this grow. Looking for the Autumn Color Effect. I understand that you need a nitrogen deficiency to get this, and if timed right it shouldn’t affect my yield. I’m on the 5th week and one of my phenos is pretty yellow. Is this okay?

Leaves yellowing
These leaves are stressing me out. I’m not sure if I’m having a lockout or if I’m not feeding enough phosphorous. Either way, I’ve been using 3 ml/gal of tiger bloom, 3 ml/gal formulex, 3 ml/gal big bud & 1tbsp of molasses for feeding. What do I do ?
