Deficiency or not?
born_it_allstarted grow question 3 years ago
Hello, Im on 3rd week of growing (autoflower) and I saw some brown points on one of old leaves. Before i only gave root juice from biobizz and now I gave just one watering with 0,5ml/l of bio grow and 0,5ml/l calmag because I saw that brown points.It's some deficiency or not? Tks

Hard to tell by the photo, it’s blurred. That could be Ca deficiency, I’ve had something similar. Spots appeared on old leaves as well. CalMag helped.

Canna flushThank you so much for the information. I have been using Plagron nutrients for a long time and have never had any major problems. OG is my first to be very sensitive. She went to sleep in the vegetation. It's not working now. Can I do a flush with Canna flush? How I use this? ThxWeek 3

General feedbackAny feedback would be greatly appreciated, to me the plant looks healthy, however it is a bit small considering it’s age, right? I’m thinking it may be because of the cheap ‘300W’ light I was using at the beginning of the grow. What do you guys think? (Video end of week 6)5 years ago

Rusty spots on fan leaves overnight, what is it? ️Last night I used some old but clean looking wire to bring branches in to the main stems.
This morning there's now little orange rusty spots everywhere. Is a soil grow, 6.3 pH used and same run off with Cal Mag every other feed. Taken the wire of at 6am in anger, was it that? 😡5 years ago

Is this definitely CalMag deficiency? Check diary for video.Before I go to over the top with the CalMag in a stupid attempt to nurse my plants back to health I just want to know for certain what it is.
The leaves are clawing, bronze spots everywhere but the smallest of the 3 doesn't seem to be suffering as much.. what is it?!Week 8

Why is this deficiency or toxicity spreading so fast!?Had a light case of what was believed to be calcium deficiency. Ph, EC and ppm all seemed normal for run off and I've halved my nutes but kept a higher dose of CalMag going. Didn't water them last night now it looks even worse, what should I do and will the end product be ruined?Week 9

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!Feeding. Deficiences

Deficiency?Hey everybody,
I’ve never really dealt with deficiencies in autos as most of my experience is with growing photos outdoors.
Does this look like a magnesium deficiency? These just appeared over night on just two of my larger growing white widow autos.
Please let me know, thanks!Leaves. Edges burnt

Nutrient Help possibly neededFor my first grow I have kept things fairly simple. I had issues with my soil PH which stopped nutrient uptake but seems to have now resolved that for the most part. Are there any other nutes that are recommended to help bud production or am I ok with what I have now? ThanksWeek 8

Recurring Cal Mag issuesI’m already at the maximum recommended cal mag dose of 1ml/litre (with nutes at 1000ppm or E.C. 2.0) and I’m still facing issues.
It went away for a few days, but it’s now back.
Should increase the cal mag dose and cut back on the macro nutes to maintain 1000ppm?5 years ago

What am I doing wrong?I’m a new grower my leaves started to shrivel up at the tips and get brown. My friend told my it’s cause over watering so I water less but the problem keeps getting worse. It’s a month old and I use 2ml calmag 2.5 of micro and grow and 1 ml micro. I only water three times a week.Leaves. Tips - Die
