Magnesium deficiency?
Eagersstarted grow question 4 years ago
Can somebody help me identify this issue please? Is it a magnesium deficiency? I believe I had a mag def a week back and since have fed 0.8EC of calmag before i add nutrients. Growth is healthy but yellowing slowly creeps in to newer leaves and curl. Runoff ec/ph seem fine.

Hey Eagers, dont be to eager to add anything until you know what is going on. Check your runoff ph and ec levels to see where you at with a tester. If your in soil only add the cal/mg once every 2 weeks or you will overdose them. Hope this helps. Cheers friend

Could be a mag issue. Could also be heat stress. Seems like you've identified and fixed the most likely cause, if it doesn't get worse, you're fine. Good luck mate!

Baking Soda for Acidic SoilHow much baking soda should I add to my water to correct acidic soil? Ph meter reads between 5 and 6. I cant afford prepared solutions (but am not opposed to chemicals) so any other DIY remedies would be welcome too

Roots getting brownMy Ph probe didn't work, PH was at least more than 0.30 (maybe 0.60) than displayed. As a result they had multiple chlorosis, now septoria leaf spots and possible Pythium since the roots are getting brown. What would you do to save the crop ? Adding mycorrhizae? Thx!

我的女孩怎麼了，這個是生病了嗎？還是太多的餵食？在他長出第二對葉子的時候這樣的現象就出現了，但是只有一邊有葉子，我查了相關資料顯示這是菸草鑲嵌病毒（Tobacco mosaic virus；TMV）
我覺得挺像的。但是不是很確定，我該繼續等幾天嗎？還是把葉子切掉。
誰可以告訴我解決方法，希望他可以度過生長期，因為他是自動開花，每一天都很重要。

Help. White widow Auto day 7I am curious about this white widow auto seedling. This is day 7. Seems to be losing a little color, but is still growing faster than the other 2 seedlings I dropped. Any suggestions on this? I have only been watering with distilled water. I have not fed any nutrients yet

intervenal discoloration, organic growGave her enzimes last week, maybe they were too much or some nutrient lock out due to a somewhat excessive fertilization (too much vermicompost)
Think I will go on with plain water to the end I think maybe the problem will sort out itself or wont degenerate too much. Any advice?3 years ago

Discolouration progressingThe first pic is from 2 days ago, now the yellow has turned to brown spots and is beginning to spread to others. I'm hoping it's an easily corrected nutrient imbalance, please help

Is this a Magnesium Deficiency?Hi all,
Day 98. Northern Lights.
1 of my 3 NL girls looks to have a bit of a Mg deficiency. I'm close to harvest so not too worried however it would be nice to have a confirmation for future grows/learning as I'm very much a noob still.
Can anyone confirm/correct me please

Yellowing between veins on 3 of 4 plants, and curled tips - 27-29C in tent - Just heat/light stress or something more?Only on 3 out of 4 of my girls, see 1 pic of sad girl and 1 pic of happy girl. Does it look like heat/light stress to you or something more?
I was running my LED 45 cm below the lights dimmed to provide 20-30k lux at plant level. Just now raised to 65cm, lux 20k.
