Leaves turning brown/purple
tiasmaaastarted grow question 2 years ago
The leaves on one plant started to turn a little pale, and with brown/purple spots. And on the other plant it starts to turn more yellow, probably Nitrogen deficiency for this one.
What do you guys think ?

They look a little underfed and or the ph may be off a little. If they were overfed, alot of your pistols would have browned already.

Flush her with pH balanced clear water and return with slightly nutrients mix.
It’s could help.

Necrotic spotsThe last day or two I’ve had a bunch of necrotic spots pop up on the lower 3 sets of fan leaves. She is at node #5 now and starting to put out pistils. Is this phosphorus deficiency? I changed the res as it was close to a week anyways. Thanks all for the help. Happy Growing!4 years ago

Pale spots on leaves...Hi Everyone,
I've noticed a couple of pale slodges on my older leaves. Picture in gallery.
Is this nute burn? Or is it a sign I need to up my base nutes? Or maybe it's a Mag Cal Def 🤔
Hoping one of you grow wizards can help as this is my first grow ☺️Week 3

What could be causing this?I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far.
I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout.
Anything else it could be??4 years ago

Rusty/dry looking tipsThe tops of one of my plants is showing some signs of nutrient/light burn, I’m not sure which it is. It’s directly under the centre of my light, it’s at 18”. It’s the one plant only and each have been receiving the same amount nutes/water rotate plants around?Any help appreciated4 years ago

2 Yellowing Fan LeavesI have 2 large fan leaves from the main cola turning yellow and 1 almost looks crisp or burnt on the edges.
It is only 2 of the leaves and by my reckoning, they are 2 of the oldest leaves on the plant.
From research, it could be the bump in nutes or water issue.
Any ideas?4 years ago

Yellowing leaves.Accidentally resolved my original question instead of liking a suggestion and I cant change it 😅
Same issue still applies for now.
I have been testing the PH going in but not out so I will try this and pass on my results after the next water 👍

Are these done for?I'm honestly thinking about binning and starting over, plants just seem droopy.
I've checked PH and TDS runoff, PH is 6.5 and TDS is around 800.
Been waiting until the soil is dry before watering this last week, plants still budding but still looking sad.
Are they done for?4 years ago
