problem with 3 of my babies.

howdy.

i looked through a few threads and see 3 possibilities for my nute problem. i'm growing matanuska tundra and stonehedge. i had one plant whose leaves look like this in veg and flower (maybe a third of the fan leaves). i'm 4 weeks into flower.



now i noticed another matanuskas leaves are doing the same thing. this one was fine up until a few days ago.


and a couple of the leaves look like this!



phosphorus deficiency? calcium? i'm stumped. help please!!

i also have one plant whose leaves are cupped under and always look a bit droopy. this too has been going on since veg.




here are my matanuska tundra and stonehedge fems. long colas everywhere!







I use dutch masters gold according to their feeding chart. i will be starting using AN's big bud next feeding. i'm watering about every 3rd day and feeding them every other watering.

i used to use many additional nutes (i mostly used to use a lot of AN products and botanicare) but i wanted to simplifiy things this time around. apparently it's too simple. time to buy some more molasses!

i'm using fox farms ocean forest and perlight and i used light warrior for seedlings/clones. i repotted about 2 weeks into flower once i found the males. so they got a fresh shot of the nutes in the ocean forest at that time. i went from 1 gallon bags to 3 gall.


i've gone from a 1000 watt (400 watt MH for veg) down to a 600 watt with a 250 watt for veg. they are in a growlab 145 tent. 18 plants, 3 gall growbags. both genetics are from sag. i've grown out the stonehedge before and i love them. they and my super silver haze were my biggest yeilders but the matanuskas are quite a bit bigger than the stonehedges. nice!

i remember a thread from few years ago that had around 100 different pics of leaves/plants and the probable problem. i can't find it anymore. must have been from overgrow.

thank you for any help you can offer!

I bet its all revolving around a Ph problem. Check out this thread, tons of great info.

The plant with the cupped leaves looks like too much water or too many nutrients. FFOF is packed with nutes and it is easy to over fertilize. When I was using FFOF I liked to mix it 50/50 with either light warrior or happy frog. Really helps loosen up the soil as well. FFOF can get so dense and water logged.

howdy wingnut.

thanks for trying but i check PH every time. it's 6.5 to 6.9 when i water.

the cupped leaves plant is just plain odd. it's been like this since veg. i have 18 fems and they all get watered and fed the same. i only used ferts on them the last couple weeks of an 8 week veg period so it's not overferting. they were doing well with just the fox farm soil. i do a 2/3rds fox farm soil to 1/3rd perlight mix. it's annoying when only one plant shows a problem. i'll have to toss out her clones! EFF them if they don't like what i provide!
