Coco problem
Reaperstarted grow question 5 years ago
The anubis (picture from day 9) u can see there was a litle calmag issue (brown dots) now, the new growth is a bit CURLY, is this because of the calmag issue? also the cheese is in the same coco/feed and has no issues at all, i use 6-9 formula + 0.5ml calmag/liter

I would have to go back and ask how you preped that coco.
That is the biggest source of issues in that medium, improperly prepared, not washed well enough, or not buffered correctly.
Coco does not technically need perlite but it sure makes thing work better, 20-40% is the range I prefer 25%.
Now yours seems that the coco was not buffered correctly. Could use some perlite but thats not your issue.
What happens is the coco begins pulling calcium away from the plant and that is a calcium issue you have friend.
Some strains will react to this situation worse than others, high need of calcium or magnesium.
Giving that plant more is about all you can do your PH is fine 5.8-6.0 are perfect.
And in coco you feed from the start of those true leaves. Gently but you feed.
Hope it works out 😀
Grey_Wolfanswered grow question 5 years ago
@TheReaper hi mate I believe you are correct in that being a calcium issue but its caused from an incorrect ph at the roots you will need to adjust the feeds ph to about 5.9 and the run off should be within a range of 5.8-6.2

plants of that size don't need calmag and if you have a good substrate they don't even need any growth fertilizer, just root stimulator. looking at the substrate, see if it has practically no perlite or vermiculite, it could be PH, but due to the age of your plants, I don’t think so, I think you’re giving a lot of water in each irrigation, the substrate is very wet, the roots don’t breathe and they do not develop soon the plant also stops developing and goes into stress. let the soil dry well, try to add some pearlite to your soil and give small amounts of water for each irrigation. good luck mate 👍

It looks like a ph issue to me. Have you checked the runoff pH?

Blue Dream Autos with Downturned Leaf Tips23 days old. One started showing downturned leaf tips on new growth; others followed. Looks off-color, at least one is in early bloom. They’re in coco, 3-gal pots, 480W QB at 50cm, 2.2 EC daily, no pH check. Problems started after adjusting watering for larger plants. Any tips?

Nitrogen Toxicity? (Day 20, autoflower, Biobizz All Mix soil, only used CalMag and no other nutrients) My other plants look fine.Is this Nitrogen toxicity? My temps are 20-24°C, RH 60-70%, DLI ~20 and they are not overwatered. Brreder says this strain is also sensitive to Nitrogen. Is Biobizz Allmix soil just too hot for this plant. Anything I can do besides hoping it powers through until it is bigger?

help in Hydro RDWC/DWCHello, my plants are now about 4 weeks old. The leaves droop and curl. The spots on the leaves are increasing. Is the PPM value too high? It's 1000ppm tds
They grow in an RDWC system with top feed. The top feed is permanently switched on. Can that lead to problems?

End of Flower, Yellow and crusty leaves ok ?Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves.
Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?

Problem with plants in the 3rd week of vegetation.I'm posting again because I accidentally marked it as resolved.
I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.
