What is happening? (First Grow)
From_ChE_Farms
started grow question 5y ago
Is what I'm currently seeing nutrient burn due to low pH? If so, what can I do to fix a consistently low runoff pH (7.1 in 5.6 out)?

Your ph is out of line and your fighting lock out. Run ideal ph water through till ph is right then re add nutrition.

I think I have nut issues?
OK here's today's update, 3/9/22. They are all doing great, they're all standing proud now! I think they needed to dry out a little, more light and needed the extra nuts. What do any of you guys think could've caused these symptoms that my girls are/have shown?

Triple question: -Why are bottom leaves yellowing this early? -Explain 'What is this!?' picture -Is it normal that when they transition to flowering stage leaves' stems curl down like in Day 56, Rebel (II)?

What are these on my leaves?
I was told perfect leaves are impossible to get, but this has to be something right? I had some nutrient burn from one week that was quickly stopped at least as far as the tips of leaves. Is this nutrient burn? a nutrient lockout of is it normal for flower? Im hoping this is norm

Fast-growers starting to show issues.
Got some issues on these fast growers. I've been treating it as a cal-mag deficiency, however I've been feeding calmag for two weeks and its only getting worse it seems. Any thoughts? PH is 6.0-6.3, PPM 444 feed, RH 47-50%, Temp 77-81f.

Yellow Leaves Autoflower
Novice grower, Outdoor. Started in a 70/30 coco-coir to perlite mix. Forgot Worm Castings until 22nd June, implemented with top dressing of Gaia Green Power Bloom and All Purpose. Overwatered at stem for a week or so. I suspect it's either an N, P ,or K deficiency (nuteburn?)

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same. I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Hi 8th week of flower. Bottom leaves have turned yellow and died and yellowing is rapidly moving upwards. I think it's nitrogen deficiency so I've added more Biobizz Grow. Would be good to get an expert opinion! Thanks

Is this nitrogen deficiency? Should I change the soil?
Is this nitrogen deficiency? I've been feeding them and using pH Down but nothing changes (pH 7.2). Should I replace the soil? They're in CannaTerra mixed with Promix. I've got some FoxFarm Ocean I could move them to.

Leaves full of brown spots
My friend doesn’t have a grow diary but he uses advanced nutrients and feeds when almost dry. He has this problem on his leaves and he can’t seem to stop it. I suggested calmag but he feed it 2ml per litre on sunday and the problem is still increasing. What else can he do ?

Leaves fading and dying, started from bottom but spreading
I’m starting to be at a loss with this. Calmag issues earlier in veg, seemed to improve for a while but now bottom leaves started to die - I thought this was just due to beginning of flower but it’s getting worse and spreading even to healthier new growth. PH (should be) fine.

What should I do from here?
I had some problems about a week ago. I investigated, and corrected at my best, but I am not sure what to do from here? Do they seem to get better? Should I do something different or just keep going as I am? - More pics and info in my diary

Hello! These spots appeared on a leaf of a GG#4 from Zamnesia in its fifth week of vegetative growth. It's not something I'm worried about, as the plant looks healthy and is growing vigorously. But I've never seen this type of spot before and I'd like to know the possible reasons for it.

Yellow spots on leaves in veg stage

What's going on with my clones? Do not have much information to add. VPD is not terribly off, DLI around 25.
What's going on with these clones? Not sure what it could be. They could possibly be rootbound. They should have been transplanted a few weeks ago but I did not have the space.
