6 weeks, yellowing leaves, PLEASE HELP!!! PICS

[Crackanin]

Got 6 females in 5 gallon buckets under a 400 watt hps. They are 6 weeks into veg. In the past two weeks the bottom leaves on all the plants have started to turn from very healthy green to yellow and yellowish/green from the bottom leaves up. They are in organic soil, have been giving them organic nutes 2-0.5-1.5. One TSP per gallon. After the leaves started turning yellow I flushed, then watered using plain water for a week. They seemed to perk up but then got worse, I thought it might be a nitrogen deficiency so I started giving nutes again this time about 2-3 TSP per gallon. No good or bad responses.

So here are the pics, taken today. Wanting to start 12-12 light cycle soon, but not in the shape they are in, please lend me your expert advice.

you said you were feeding them every watering?

I started feeding them at about 3-4 weeks, one TSP of 2-0.5-1.5 per gallon every watering, then they started getting yellowish/green, so I flushed, then did not feed, just watered for the next 2-3 waterings over a week. They then got way way worse, as you can see in the pictures.

why dont you wait another week.

i believe its a cal-mag or iron def. ready to get worse

I dont think anyone here is not guilty of ever having yellow leaves. Plus it looks like the yellowing is only affecting your fan leaves.

The bottom fan leaves on my outdoor plants turned yellow once my plant reached 2.5 feet so I just removed them and they are doing fine. From what I've read when you see a unhealthy looking leaf you remove it.

Anyone know if it is possible to have nutrient lockout in soil? If it is then maybe you should adjust the PH of your water.

Good luck

What should I try to do in this case?

 

[Ready2Inhale]

nutrient lockout can occur in any medium i believe

I had the same problem in the 4th week, but it was due to overwatering. I was doing it every other day. I waited 3 days, with no water, then it came they came right back within a day. I didn't have to start pruning for a 3 more weeks. How much are you watering?

if money isnt an issue then get some Botanicare Cal-Mag(about $20) but worth every penny from first hand experience...on a budget just get some form of dolomite lime...bene-fungi plays a big part too...

Watering every 3-4 days, once soil about 3 inches down is dry..

I looked at iron deficiency/mag deficiency pictures and it doesn't look like the plants in mine, mine the bottom leaves are like banana yellow.

thats why i said a cal-mag def. ready to get worse...but if all else fails the only problem i can think of is a nitrogen def. add some solid N to tha pot...get some Fox farms tomato & veg. feed in granular form(natural & organic) and put a couple teaspoons on the top of each plants medium & water(worked for me)

Is there anything that you would suggest I try, besides buying more nutes? I am broke, is there a cheap solution?

 

[Ready2Inhale]

i apologize...i realize no one has a money-tree growing in their yard(is weed considered a money-tree?lol)...peas are an excellent cheap & natural nitrogen adder...so go & load up on a few canned goods

I would bet it is a N deficency and way overwatering. If you got those tiny plants in 5 gallon buckets, you should not have to water for 1-2 weeks. Not 1 - 3 times a week. That is way too much. Let the roots get some air once in a while instead of constantly soaking them. Your yellow leaves might not recover but watch the new growth. Let it dry out and then water with your regular nute formula but don't water again till it completely dries out. You want to soak the soil with a good amount of nute water, then you want to let it dry right out before watering again. Hope this helps.

I split a gallon of water between 6 plants that are 15-18 inches tall every 3-4 days, that's still too much water?

 

[Ready2Inhale]

in my experience with 5 gal buckets...if you have gooddrainage holes then 2 quarts per plant is optimum every 4 days

i think that if you had a way to test teh concentration of buildup in the soil that'd be ideal, but for the time being why not do a 1/2 the normal dosage, keep strict watering schedule and 18-6 lighting. let them veg for a while and get them back up to standard. Also, when you flush, you flush to get rid of salts but then add a mild nutrient dose to replenish the total loss of everything. this is more from the medical cannabis bible by jorge cervantas than from me
