Did you look at the leaf problem identifier on the main GWE site? More info helps - strains, soil, nutes, pH, etc.

Can these plants be saved? I've done a number of grows and have never had issues like this. I'm growing Barney's Acapulco Gold in Fox Farm Ocean. Transplanted them into the fabric 5 gallon pots 5 weeks ago. They initially were doing okay the first two weeks but never got lush and growth has been stunted. The light schedule has been 18/6. Temp 78 with lights on and 68-70 with lights off. Using Mars-Hydro 600 watt LED with both growth and bloom on which is what I have always done. Using a humidifier keeping humidity at 35-50%. I've only given them a very small amount of nutes twice. I was using distilled water but had to switch to spring water a week ago as no one has distilled in stock in my area. I'm adjusting the water PH to 6.4 to 6.5. You can see the leaves are pale, yellowish and there are brown spots and a few leaves are dying. Any ideas? Thanks a lot!

Looking for help with 9ne of my girls. Not sure if it's a mutation, pests or virus? Any info would help.. deformed leaves, some curled, and yellow discoloration. She is growing at the same rate as my others, but looks quite different.

I will suggest some "Voodoo Juice" it is not a nute, it helps root growth, check it out. I use it on seedlings, when transplanting, and when going into flower.

I have ordered some, will probably come tomorrow Leaves on the big colas are yellow but everything else seems okey
I fed her yesterday with nutes and calmag.

IF you can get them into more soil without disturbing the roots. However IF the roots are damaged its bad, real bad in flower.
Are they in cloth or what? A bud here drops the cloth pot in the larger pot (or the ground) and grows on, absolutely no damage that way. It also takes some time for the roots to grow through them, and "Smart Pots" (brand) the roots should not grow through (its their cloth). Some cut the pot or just cut holes in it, carefully as to not damage the roots.
I myself would hit them with a 7.0 flush (you may want to feed after) and get that PH up to 6.5-6.8 range. (in and out)

I have replanted it now, the pot I had was plastic and maybe 4 liters 🤦 transplanted it to a cloth pot and filled it up with canna Terra soil, gave it some water with 6,8 Ph. The roots were bound of course, but really not that bad.

I have learned a lot during this time and have done so many errors
. I have 2 00 KUSH in veg now with top teir environment, medium and nutrients.

If she survives, great. Otherwise I have learned a lot and these next two will be fire 😊 thank you for helping

Looks like a PH/root zone issue so whats the PH?

I'm afraid you might be right, the pot is too small. Any point in relocating to a bigger one at this stage?


Runoff is still a little low, around 5-5,5

I'll upload better pics, I fed her about an hour ago and added 0.6 ml of calmag along with flower nutrients.

I get insecure but i really think calcium deficiency is one promlem. The dark spots on the leaves appears over night

I really appreciate the help.

I don't know your camera settings but she looks hungry to me, a lighter green color. Did you help dry out the pot out and feed her yet? What do you think, per GWE's leaf problem identifier?

[Deriksson]

She's getting more yellow leaves. No more spots I think but something else, is it because the flush?

[Rwise]

I would say 5 weeks maybe more depends, yes feed her flower food.

[Puglover1]

A fan directed toward the top of the pot might help the soil dry out faster. At pH of 6.5-6.8 cal-mag would uptake better, it's worth a try, I don't know much about your nutes. If you flushed 'crappy soil' you probably want to feed her on next watering, you may be in flower longer than three more weeks. GL!

[Deriksson]

Raise the PH to 6.5-6.8 range (go for 6.8)
The spots will not go away so watch the new growth, they may look bad but they are still feeding the plant so dont remove them yet.
Cal/mag may help as well.

I flushed it with 6.8, should I continue with nutrients next feed? Has about 3 weeks left of flower. Feels like its gonna take a week to dry out now ( as I said, crappy soil with low drainage)

Ok I'll let leaves be.
