Hey guys, week 8 of flower, 5 gal bags ffof soil, floranova bloom down to about .5 tsp/gal, watered every 3 days, what are these leaves doing? Is this fade? Or some type of nute burn from lowering my nutes and it using up the residual in the soil? Ph of soil is 6.5, hlg 320w light is 18 inches away, im not sure what this leaf condition is! Leaves turning this color are pretty brittle

Also do these things look close to done?

Any advice is greatly appreciated guys!!!10067B86-D0DB-47BB-B8F9-85EDFBDA4861.jpeg505C1200-C9F9-49AB-8E69-26411A9A2246.jpeg

No, not fade...it's a K deficiency, BUT...you're too far along to worry about it, so don't. You'll have a nice harvest; not to worry. Take notes on what you've fed and so forth, for your next go round. Good luck.

what makes you think it K def?
if the spots are orange, in my experience, that is calcium def.
if the spots are golden yellow, that is magnesium def.
or at least, that's the way I understand it.

You've got numerous toxicities, deficiencies and heat stress after only a cursory look. When I see so much happening at once, I immediately suspect either the nutrient solution, the roots or both.

That is most definitely not normal "fading" at end of plant life.

What EC/PPM of nutrient solution had/have you been giving the plants? I see you're using a "Bloom" nutrient bottle, where's the "Grow"? Using only bloom nutrients is but a tiny fraction of what your plants need. Adding only some, but not all nutrients during a grow can cause all manner of problems. You're essentially missing all or most of your Nitrogen and micronutrients. If you are skipping providing the liquid in the grow bottle, this very well could be the source of all your problems.

They've got a couple of weeks yet by the looks of it, so take the time to try to dial this in before they're done, just for the experience if anything else.

After noticing dark green foliage, and slightly burnt tips but overall healthy plants, i lowered amount of nutrient solution from 1.5tsp to .75tsp per gallon. Now leaves are turning this color. Also, only stems that are doing this are offshoots that have a smaller diameter stem compared to main stem colas, is there a correlation? So continue to feed til end?

Again, have you/are you using "Grow" nutrients along with "Bloom", or just Bloom?

Do you have an EC/PPM meter? What's the pH of the mixed nutrient solution that you're giving the plants?

Only Bloom, do not have ppm meter, nutrient solution ph 5.5, soil 6.5.

I take back what I said about needing Grow. After a quick look, it appears as though Bloom may be stand alone. Don't quote me on that though, you'll have to investigate further if you desire.

About your pH... it appears you're in soil and your liquid pH is too low, you need to look into this as well. 6.0-7.0 for soil. You'll have to verify whether you're using actual soil or if it's a mix of peat and coco. pH matters tremendously, and it's different for various mediums.

The chattered leaf margins generally suggest a K issue, but I'm just one man with an opinion. I do agree with what you're saying in terms of the Ca, and while he looks short on it to a point, I think he / she has bigger issues.

Floranova bloom is fine, ffof is kinda iffy. Your plants are over fed at the moment. I wouldn't feed them any more since they are almost done. Even low doses of Floranova will build up in the soil after a while.

FFOF shouldn't require much more feeding. I'm not sure how long you've been feeding, but it's obviously been a while now because you have low pH damage, dark green leaves indicating too much nitrogen, and leaf curl. the curling might be a mix of pH and air temp that's a little too warm. it almost looks like some heat damage with brown areas in the middle of the leaves. This is strange because the orange spotting might be cal def but you've given it so much fert that low calcium seems unlikely. so close to harvest, I would just flush it once, then give nothing but water from here and let it die. harvest. could be worse I guess.

Ppm and ph. That’s all you should be worried about. Any major brand should give you lovely plants if fed at the right ppm and pH.

I have also had an issue with the leaf colour last week or so. I think they’re ready to go now but I’m scratching my head why trichomes not booming, , buds not bigger and there not really sticky. Been using Nutrients and booster recently. Gunna be like 12 weeks now if not longer so they must be ready but bud size is poor considering time and not had burst in size last few weeks like my last.
Any ideas? It must be ready to cull now. Read up to check when trichomes are 50% brown it ready but they look different in daylight to bulb light so my head is mashed and it’s in cellar so not much daylight to check properly. I’ve took pics in both lights to show.
Gonna flush with just water for a week now anyway (usually water every 2-3 days) but ya think it’s ready for the chop? Just mashed as to why it’s not busting massive buds and sticky as f**k !
Also can’t get humidity down even with good set up. Saying it’s 70% in dark 50% when lights on, even with a dehumidifier.
