started grow question 5y ago
We are in the middle of week 6. I think there is a deficiency or a toxicity. I couldn't understand why. Could you please check?

If I had to guess a bit of nitrogen excess, perhaps slight calmag deficiency.

Do i have a deficiency or an excess? Burnt spots on leaves, rusty colors on the edges, purple petioles.
I am running through some issues with my plants right now. I switched them to flower two weeks ago, and early this week I started seeing some rusty colors appearing on the edges of my leaves, this rusty colors (bronce like). Where the bronce appeared, it's starting yo burn.

Hi Legend, Not sure about it. Magnesium, Calcium, Ph. Maybe uptake or loss. She is growing well, big healthy. Ready for a second round of clones. After, I will let her sign in a bigger airy pot. Thank you for any suggestions ๐

Nutes in flower
Anyone have any feedback on running high ppm in flower with RO water? Does SLF-100 help flush unresolved nutes? My first grow but I think I'm blowing it, please look and tell me what I'm doing wrong.

Flushed plant for 36 hours out of fear of Nutrient lock. Not sure what to do now. Love to hear from the experienced folks!
Plant has been slow to grow last 5 days. I thought I was over feeding (puffy dark green leaves, burnt tips) so the last 36 hours I have been feeding RO water and H2O2 to flush. Not sure what to do now as I am looking at her. Love and appreciation for any suggestions!

Should I remove foliage affected by deficiency, or just let it ride?
Autoflower started showing sign of deficiency at week 8. Assuming CalMag, as I filter my water and affected area is new growth at top of plant (see pic). 1) Can someone confirm CalMag deficiency or something else? 2) Should I remove affected leaves or leave them be? Thanks

Should I use a pH up -product?
After mixing nutrients with my tap water, the pH of the mix is around 5.5. Should I use a pH -up product? Plant is showing a slight nitrogen deficiency. My tap water base pH is almost 8.0, but the Biobizz nutrients bring it way down. I am using 50% of the recommended dosage.

More rusty spots
See this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing. Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.
