Newbie101started grow question 4y ago
My plants always had dark complexion. Feeding less N didn’t change anything. Last waterchange I didn’t add(extra) calmag. beside the calsium and magnesium that was in the GH flora tripart (hydroponics). Is this a calmag deficiency? Notice twisted/mutilated leafs on some top growt

P.S. - Try and keep your grow space clean and tidy, all those fallen leaves are a prime place for pathogens to breed!

No, it is burning and not a calcium or magnesium deficiency, which will show up as polka dots on the leaves.
Feeding less nitrogen will not show on the older leaves and will take 2-3 weeks to have any noticeable effect on the new growth.
There should be more than adequate amounts of cal/mag in the GH nutrients, cal/mag is really only an issue when growing in coco coir.
A few funny leaves is quite normal, no plant will ever have 100% perfect leaves, 100% of the time.
Your plant is very dark green, going to half strength nutrients for a week or two might be adviseable and will not cause any problems.

Is this nutrient burn?I'm pretty sure this is nutrient burn. Using hot soil with a bit of extra worm castings on the top layer. The pH was also too high (approximately 8) but has since been corrected (now 6). Next layer on top came in nice and healthy. Can someone confirm there's nothing to do here?

Started Flush - Rust color on edge of sugar leavesSo these are starting week 8 of flower - I just started flushing these- they’re in coco. Within the last day or so they’re developing these rust colored orange areas on the edge of sugar leaves. Is this just natural during flush with coco? Or what’s going possibly goin on?
Thanks

Please take a look at the last photo of week 10, the close up of a cola. Does this appear to be the start of a K deficiency? There is tip burn on some of the plant as well. Refer to my notes with watering issues for past 2 weeks. All nutes listed ph ppm are correct. Thanks!!Week 10

The leaves are wierd shaped, but growing fastHi everyone! Please tell me, is it a consequence of leaf scorch with light, or incorrect watering, or I was very in vain in the beginning added root booster? The big question is, is it worth waiting for a potential recovery?There's nothing like it at google
