Spotty/dying leaves towards bottom of plant.

day 20 or so of flower.

400w HPS. 69-75f temps, 40-55% humidity. 12/12 photo

FFOF soil with tbsp of dolomite lime added per gallon (5 gallon buckets).

Feed cycle is water, water, feed. Just fed it this morning. Roughly 900ppms with 1 gallon of distilled water.

The buds are looking fantastic and plant seems overall to be very healthy.

I'm worried though, because after I fed her this morning I posted some pics on my journal and someone suggested it could be nute burn. Can anyone else chime in on this? If it is indeed nute burn, is a flushing immediately in order or can I just wait and see?

Thank you for all your advice.

bump for justice

Flush always when in doubt.

what's the ph? Check the ppms of the runoff. If its low, you're not burning them. Are you using calmag? See any bugs?

Yeah I'm using calmag. Nah I don't see bugs. There is dolomite lime in the soil, but I can check runoff next time.

Is calmag and dolomite lime together too much? There is probably a little less than 1 tsp each gallon of soil (5 gallons). The amount of calmag I've been feeding it is very small, like half a tsp every third watering (its feeding time).

All these small leaves are falling off right at the base of the stem, where it connects to the main stalk. what could that be evidence of?

thanks guys

new pics

This is another shot of the bottom of the big girl. A lot of the leaves are exhibiting these symptoms on the lower part of the plant.

The top of the same plant. Obviously, she looks very good from this angle. Somehow she has 5 or something tops, don't ask me how. I must of fim'd somehow

The bottom of my other girl in there. She isn't as bad as the other girl, but she is exhibiting similar symptoms at the base of the plant.

A wide view angle of the plant above. Looks very healthy from this view.


I really need some expert opinion here. Keep in mind, I fed the first girl today with about 900ppm mixed into 1 gallon of distilled water. I want to stress her as least as possible, can I get away without flushing and just watering her without nutes for next week or two?

Thank you guys

It may not be getting enough light which is perfectly normal for the bottom of the plant may not be a problem. If there is a nutrient deficiency look into the mobile elements because if the bottom leaves are showing deficiency its because the plant is stealing the nutrients from the older leaves to give to the new growth.

This is what I was theorizing, but someone was suggesting burn.

In any case, I think I'm going to continue watering/feeding as normal. Until I see yellowing or something on a leaf closer to an actual bud site I don't think I will worry too much about it..

If anyone else has anything to add I would love to hear it. Thanks guys

NOTE! I was having this exact problem until tonight. We went out and bought bigger containers, flushed the girls, and transplanted them. They got happier within hours. Those leaves were caused, WE FOUND OUT, by not nutrient burn, but ROOT ROT and CONSTRICTION.

So in conclusion: TRANSPLANT.

You sir are a genius

This explains everything. I snapped off the tip of a dried out root that sprung up at the base of the stalk for crying out loud.

I don't really have more space. This girl will have to deal with it I guess?

The top growth looks fantastical, and no yellowing at all. I did, however, notice some slight yellowing at the tip of one of the leaves closer towards the middle of the plant, so I guess it is definitely moving from the roots up.

I have a feeling this plant has too much root mass though. Could this also explain my issues? From what I've deduced, I have two options.

One: flush her out nice and good, potential stress?

Two: Leave it be, accept that leaves are going to get a little yellow/crispy/die at the bottom when so much flowering is going on at the top. Potentially allowing the problem to continue?

I don't want to transplant, I don't want her to get bigger and I've read enough to figure that a transplant isn't necessary at this stage of flowering.

I think what I want to do is option two and just flush immediately if I notice yellowing towards any bud sites. Do you guys think this is reasonable? I should also note that there is definite bud growth still occurring.

Thank you for reading

I am having the exact same problem in veg.. crispy ass leaves dying all over the bottoms of my clones. I lost all my ladies in the last cloning because of this shit too. I thought it was lockouts caused by ph fluctuations, so I would flush flush, then that didn't work so I thought it was fungus gnats, so my gnatrol didn't work either obviously.. never figured it out before they died, and now I have the same shit going on! Lol. Nice ladies though dude, they look good other than those leaves nukka

thats phosphorus (P) deficiency holmes.
