what's up guys, currently on my 2nd grow, 3 weeks into flower. strains are sour d and kong. growing under a 400w hps, using all of the house and gardens nute line except the amino extract(picked it up late and didn't want to introduce it to late into the grow), growing in roots organic soil. it started about a week and a half ago with one or two leaves having little deadspots on them. i washed my watering pots and everything to make sure that nothing was transfering from the side of the pot when i water onto the leaves. did some reading up and thought that it might be that my ph was to low. i was running it at 6.2-6.3 because that's what house and gardens recomends to get the max out of the nutes. in the last few w.aterings i up'd the ph to 6.5-6.6. and have not seen much signs of improvement so far.if anyone can please help me identify what the hell is going on so i can get it corrected asap. thank you very much!!!!!!!!!IMAG0091.jpgIMAG0092.jpgIMAG0094.jpgIMAG0095.jpg

If my plants are lacking phosphorous and I'm running the Lucas formula (8ml micro/ 16ml bloom) in an aeroponics tub under 1000w HPS, what can I add?

I came across this neat little list that can probably help a lot of people out. If you like it check my post in the General area...I need some help! Quick Deficiency Guide Nitrogen: Entire plant is light green in color; lower leaves are yellow; growth is stunted.... Phosphorous: Entire plant is bluish-green, often developing a red or purpleish cast; lower leaves may be yellow, drying to a greenish-brown to black color; growth may be stunted... Potassium: Leaves have a papery appearance; dead areas along the edges of leaves; growth is stunted... Magnesium: Lower leaves turn yellow along the tips and margin and between the veins; the lower leaves wilt... Calcium: Young stems and new leaves die... Zinc: Leaf tissue between the veins is lighter in color; yellowed; papery in appearance... Iron: Leaf tissue appears yellow, while the veins remain green... Copper: Leaf edges appear dark green or blue; leaf edges curl upward; young leaves permanently wilt... Sulfur: Young leaves turn pale green, while the older leaves remain green; plant is stunted and spindly... Mananese: Growth is stunted; lower leaves have a checkered pattern of yellow and green... Molybdenum: Leaves are stunted, pale green, and malformed... Boron: Young leaves are scorched at tips and margins...

no don't give them any thing. if u do give them like 1/8 of wat u should. keeping the tep an humd in rang is the most important thing. the really don't need much an the shouldn't loss color as long as every thing is in rang.

it real do matter if ur plants root bound to much. u will just need to water an feed a lot more. I grew sum big 6 ft plants in 2gal pots an it grew nice. I just had to water every other day an large feeding twice a week. I think ur plants yellowed an died cuz the starved to death. I could be wrong but I no u can grow big plants wit root bound roots wit no problems.

I have had the same reoccurring deficiency for the past several grows during both veg and flower phases.
After reviewing several posts including the Guide to Nutrient Deficiency and Toxicity thread I believe it to be both a potassium and magnesium deficiency.
I was hoping to hear from some growers who have more experienced then it when it comes to this aspect.
I will measure runoff ph and ppm as soon as I get a chance.

Specs:
-indoor
-Strain: DJ Short's BlueBerry (first 4 pics) and a True OG (final 5th pic)
-pro-mix hp (premix 10gals of promix w/ 2 tblsp of dolomite lime and ironite from Home Depot)
-feed using RO water
-pictures are of 4 week old plants vegging
-soil drenched once every third or fourth day depending on each plants water uptake
-nutrients every other watering at half strength using Pure blend Pro grow, silica blast, & liquid karma

Hello all! Im looking for a little help...Im a little confused as to the problem/s below. Ive been growing for awhile and have recently ran into some problems. I have been an organic (amended supersoil & compost tea) guy now switching to Jack Duo. Just got them today. Anyway, have been having trouble cloning lately in my DIY aero cloner, slime on stalk, dying before they can root, used to be 100% last pull was 50%. So i've went back to heat dome. These last clones rooted and have only got Act teas. Also i have RO water (30 ppm, 7.5ph) I will include some pic below. My fear is a fungus or blight, tho they could just be hungry for some food and be deficient. I will be hitting the with Jacks Classic 20-20-20 but any of you thoughts would be helpful. hope the pics project what im seeing. small black dots. and issues on the edge on the fan leaves.

just a quick question... my lower older leaves still seem to be healthy, but are somewhat drooping as if i was over/underwatering. would this be related to magnesium defficiency as mentioned in the guide above? its only the fatter lower leaves, not any else. this is my first post btw :)
