we need more info. Nutes? Feeding/Watering schedule? PH? these things will help determine the problem

Yeah i checked it there and its PH 7.
7 is a little high, would be best if you can get it down to 6.3-6.5. You might be experiencing nute lockout.

Whats up Old Toby. For every gallon of dirt you flush with 3 gallons of water. So if your plants are in a 3 gallon pot you flush with 9 gallons of water.

IMO, if you are watering daily you may be over watering... by watering in the evenings the soil is always damp over night and you are subjecting yourself to a root fungus... IMHO... I just had that problem and it looked EXACTLY like that, started primarily on the lower leaves and worked it's way up the plant as the fungus grew below the soil, by the time it breaks the surface it's too late..

Not to mention... the planters in the photo appear to be quiet small...what size are they?...remember, the larger the planter the larger the plant, you may, and/or may not, want to transplant into larger containers (Just an observation)...

I'll co-sign Advocates statment. Overwatering is the #1 mistake. It is better to underwater than over water. Mine may droop I water and perk right back up. but over watering is much harder to fix.
Also what helps "promote" this fungus is the fact that the Roots were depleted of oxygen due to the constant moisture. This causes root rot. Classic symptoms are what you have here.
MJ does like a dry spell helps promote the roots to spread out and search out water. More roots = healthier plant IMO. (In dirt of course)

Watering rule of thumb. If you stick you finger two-three inches in the surface and its dry. time for water. I also can't preach enough about "proper drainage". You have to have holes in the bottom to drain excess water. I've had pots not drain good. It was dry at the top and a mud/sludge pit of yukkie stuff at the bottom. I only water about every 2-3 days. (depending on age/size of plant, flowering period sucks it up for about a week or two when its going throught its stretch).

Yeah 2 of my plants are about 4ft tall while my 2 others are a bit shorter than that by a few inches, they are growing well with healthy leaves from the 3rd node up, GOOD TIMES, its just the bottom leaves that are crusty lumps of misery, BAD TIMES. Dya think if i left them alone and changed my watering to morning times they will be ok?
I never thought it would be this hard work with growing weed.....

It isn't too hard.. just make sure the soil is dry over the top few inches and you'll be fine!
