answered grow question 6y ago
if you're going the organic way yes dolomite lime should do the trick, but I would suggest using GHE Ph Up, that way you water the plant until the runoff comes out between 6.0-6.5, this will give you faster results.

Do these look healthy? Thoughts? I'm new to hydro/growing
I have autos growing in a dwc system being fed half the regular amount of hydroguard, calmag, and grow/bloom. 1 plant is a week younger. The dark green plant looks like its leaves are clawing and has big brown spots on the leaves. The other has some brown dots and little yellow.

Leaf damage/discolouration
The Skunk has been getting a lot of leaf issues. I have been trying to stay on top of picking them off as they appear in case it's rust or similar and can spread. It almost looks like cal mag deficiency, but I'm feeding cal mag each feed. This is the only one effected out of four

Browning spots after H202 rinse.
Hey guys! My first dwc and I’m having an issue. So after about a week my water was cloudy. I rinsed and washed the bucket, fixed the area where light was getting in. Then I rinsed my cube and plant with H202 3%, 1/3 to 2/3 water. Changed out nutes but now look like this. ?

Too much light or other deficiency
Too much light or some other deficiency? I’ve been having some issues with yellowing leaves and some other issues with browning and wilting/curling which I thought was initially nutrient lock but what I noticed is all four plants were not stunted and continued to grow normally.

Could someone help me to identify the issue my plant has?
This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.

Leaves keep turning brown and yellow
It all begann with what I thought was light burn. I then considered it CalMag deficiency. Giving it CalMag did not stop it. My current guess is too low pH due to strip inaccuracies, so I gave it around 8 today instead. What do you recon, why could it keep getting worse?
