Calcium deficiency?

[TripleCchronic]

My plant is a Barneys Pink Kush that broke the surface of the medium 13 days ago. I had what I believe was a magnesium or iron deficiency so I added 10 tsp of Dutch Nutrient Cal Mend and 18 ml of Advanced nutrients B-52. Unrelated I also added NPK RAW microbes. All this to a 5 gallon dwc reservoir. Iv been keepong my ph between 5.7 and 6.4. My rh is 60%. Temp 23.5. Ppm 1000. Feeding GH flora trio. Last reservoir change I put 1 tsp of each nutrient plus the additives I listed above. Im co sidering doing a folial feed once my lights turn off.

Careful. Young plants don't need much at first. Looking good. I don't see a need for anything extra at this point.

What about the brown spots in the second last picture? Am I being over cautious by being worried?

That could be the beginning of a Magnesium deficiency but try not to do any knee jerk reactions. Take it slow. You already made some changes to your res so for now just sit back for a couple days and see how she responds.

I made the changes a week ago. Is it to soon to increase the cal mend? I added it at 1/2 the reccomend strength.

Oh I see. Well if it was a week ago you could offer her another 1/2 strength dose of Cal/Mag but be patient for change. Takes a couple days to really see the response.

Yea it took a few days for sure. The first few pics were from when I first noticed the magnesium issue and the last few you can see the yellowing getting better. I will try cal mend at full strength on my next reservoir change on the 14th. Or do you think waiting till the resevoir change is to long?

That's only a couple days away. She will be just fine until then.
