Ok, Transplanted the ladies, they are looking much happier this morning!! Don't know why the f*#$ I didn't transplant them earlier!!! At least I know now what they look like when they express claustrophobia :wall:

Yes, it is a starter plug indeed. Started from seed a few weeks ago. I am planting them over into 30l pots this weekend. Do you really recon its because it's root bound, I know they can show some strange symptoms when they get root bound.

Hey guys. I have something happening to my new plant and can't seem to figure out what is the cause. I use biobizz grow 0.2ml/l as they are stil small. RO water. 0.4ml/l silicon plus, 1/4 teaspoon cal mag nitrate and pH to 5.8. Light is far enough away, so it's not light burn, and not heat...

Does anyone on this forum do DWC??

It is pushing the 5th Node. There is no visible nute burn on any of my plants, including the sick one, so it cannot be too high. All of them are thriving and look very happy, obviously except the sick one, which the new growth also looks healthy. I am going to pull it, as it seems to progress...

Did look healthy on new growth but now it has definitely gotten worse. Now showing up on top fan leaves.

The res is at 790ppm, and it is only on its 4th node, so don't think I should push it just yet. I don't really know if it is a deficiency. Looked up all deficiencies over the last couple of hours and nothing looks like this. Thinking it might either be root issues, genetic disorder or a parasite.

Low Temps on foilage? I have a geyapex 300W with a pretty potent cob in the middle, will add a pic of light spectrum. It is only a small 800mm x 800mm x 1.2m tent and should be enough. Root zone is at 25.3°C and tent at 23.4°C. It is winter here.. The other plant in same tent is thriving, same...

PH is fine, 5.8

790ppm

As mentioned, Cal/Mag Nitrate is being added to my res at 3tsp/30L Don't think it is a deficiency, I know deficiencies and this is something that I cannot find the answer to. Calcium deficiency also starts off with little brown spots

Hey guys. I am having some troubles with my new grow, hopefully someone can help me out. I am getting this blotches on my leaves and it seems to progress very quickly. See attached pics. First of all, Cannot be heat stress, my tent is at 23deg Celsius. Cannot be light burn as light is 1meter...

Than Thanks for your reply!! Good info! I will flush them tonight and lower the ph to 5.8 and keep what you said in mind. Will let you know how it goes.

I had a look again at this chart, and it looks like it might be ph problems. Boron, Copper, Molybdenum, Iron, Calcium and Phosphorus can't get taken up above 6.0ph She is at 6.2ph Maybe that is why she was happy at 5.8-5.9-6.0

But then the top of my cola's would've felt the burn first and they are fine, it is a bit lower on the cola where the light burn type of effect turn up. 400W DUAL ARC HPS

It is mostly the yellowing areas on the leaves with the browning edges and spots and the tiny leaves on the cola's starting that light burn like thing from the tip of the leave heading towards the head. The tiny white specs was the mites indeed.

:cry: That's no good news!! Thanks for the heads up though!

Yes, it is mostly on the uppermost part of the plant. I also thought it would be light burn on the top of the cola and did move the light up a bit. It is still continuing even though I have about 40cm between the top cola and the light. The airflow and wind in the tent has been the same since...

She has been happy with the amount of nutes I gave her after changing to 12/12, and after switching to flower nutes for the last 4 weeks.(No Nute burn) It is only in this last week I started noticing this happening.

Thanx for the reply. When I switched over to 12/12 I fed her the same nutes as in veg for about two weeks, then I changed over to flower nutes up until now
