Bottom leaves turning yellow, with brown spots. And the tips of the top leaves are yellow aswell.
BLAZEDstarted grow question 4y ago
De onderste bladeren van mijn plantje hadden in het begin witte vlekjes en nu zijn ze helemaal geel.
De bladeren daar boven worden nu ook geel, en er komen bruine vlekjes op.
En de puntjes van de bovenste bladeren zijn ook geel.
Wat kan de oorzaak zijn?

From what I'm seeing in all of your photos in your diary, the bottom leaves are acting quite naturally and dying off. This is completely normal and certainly not a magnesium deficiency (that doesn't start on lower leaves!)... but I'm also going to say that at her age it's past time to be giving her some decent grow nutes - not just the silica. Don't shock her by giving a full dose the first time you feed - go a little slowly and give her 1/2 strength for the first feed - you can increase it next week ... I think you'll see she really appreciates it!
As for those bottom leaves, you can cut them off and let the plant put all its energy into the top leaves and bud sites. She's a very pretty plant and is going to do you proud! Just give her some food!
Good luck!

This plant needs a growing nutrition that is rich on Nitrogen (N). You can use a organic growing nutrition. Than use it till you see the first white pistils. After that it is time to switch to a Blooming nutrition. The blooming nutritions are rich on Phosphorus (P) and Potassium (K). You can use any brand you want and you can always do some research at the nutrition section from this website. When you want a organic nutrition I can advice Biobizz.

It looks like a some kind of Magnesium issue since it got brown spots on the older leafs.
I read that your water is at 08 EC to start of with, and that's really high. It probably already got lots of magnesium and calcium in it so its mostly due to a lock out.
what is the PH of your tap water?
I would reccomend doing a small flush with some RO water or distilled water and a small dose of nutrient to see how the plants react.
Also get a home water test to check the quality of your water to see what you are dealing with.
Depending on the outcome you might need an RO filter or to adapt your nutrient accordingly.
Good luck

Burning Edges/Yellowing and Drooping?The yellowing has gotten worse and I'm noticing slightly burnt tips/edges and some droop. Could this be burn/deficiency or over/underwatering? A combination? Is there anything I can do to fix this early or is it just a matter of giving them some time and less nutrients? Thanks!

Lower leaves yellowing and wilting quicklySoooo Just went to water this beautiful lady and as you can see from the pictures 2 days ago and she was healthy.
So this evening i found that the lower large fan leaves and the smaller fan leaves on bud sites are drooping and yellowing. This looks like its nitrogen or lockout?

Yellow leavesHi guys, unfortunately because of an emergency I had to leave my 2 babys with some friends for three weeks. At the bottom some yellow leaves and like burning signs. I don't think it's because of over nutrition. They didn't get any for three weeks. Might be not enough nutrient?
