Several deficiencies not shure what to do

Hey guys,

I'm experiencing several problems with my first grow, as expected, and am not shure what to do now.

Details:
Currently entering the 4th week of flower with 6 white widow and 6 critical mass
Using Biobizz Grow, Bloom, Top Max at the recomended amounts.
Soil is biobizz All Mix
Ph is on check
Temps between 22/27celcius
Letting some run off every wattering
Been feeding nutes almost every wattering, since they are organic I dont think thats a problem?
Running 3 x 600w HPS on 4x8 Grow tent
Nice air flow with good intake/outake
Dont know what my EC is so far but I know that my tap water is hard on its own.
This week I started with some molasses and plain water and will probably try and had some epsom salt since lots of people are saying that with biobizz mag problems happen a lot. Will also start giving them some Fish-Mix from biobizz instead of Grow to see if it makes a diference since it has more nitrogen available.

Problems:

Mainly the white widows have started to develop some realy yellow leafes and some of them with brown spots.
Some white widows are turning lime green/yellowish all over the tops.
Getting a lot of red stems all over the grow.
One white widow and one critical mass top leafes are curling upwards and looking very rigid.

Pictures:



Any help is greatly apreciated since I'm a bit lost atm.

stop the salt and molasses.
stick with the fish.
try plain water once in awhile. allow soil to dry before watering.
save for a better org system. theres a grow box that rocks, google it

I just did the molasses once and haven't started with the Epsom at all. I always allow for the soil to dry well.

whats your measurement of feed to Liters? and whats the bottle recommend?

I'm feeding approximately the biobizz recommendation

Anyone?

Pots need a good water only-ing. Then after all the dark yellow runoff starts to run clearer. I would try half of the dose of nutes and definitely not add Epsom or molasses.

It looks like salt buildup. Iron is getting locked out now I think from the light top leaves. I use an organic nute (no additives just base grow nute in soil) and still have to wash out excess salts sometimes. I also never need anywhere near the max dose. The plants roots can only take so much. And it is likely acidifying the soil but the watering will re charge the lime or buffer and things should return to normal in time.

Is it possible that they're also root bond? They're in 3 gal pots and stoped going at 3' buy still have at least 4/5 weeks to go

all my plants are root bound, all the time, in their cups, then in their bags, then in their pails all the way to flower.

once in flower you best leave them be. If you want bigger plants next time try a five gallon pail.
my one gallon grow bag

That likely doesn't matter halfway through Flower. The plant is not trying to grow lots of roots then.

I flowers 4-6 oz plants in 2.4 gallon pots.

You probably have enough food in your pots, so work on your delivery mechanisms. You gotta run AACTs and myco fungi to really keep them healthy through flowering.

and at what point are they "root bound" in that container?

When the plant starts to exhibit weird deficiencies I guess. All my pots are more full of roots by the end of flower than I would let them get during growth.

I get your point though. I have had pretty large plants in tiny buckets and people flower ounces in solo cups.

I've kept moms in a 2 gallon pot till there was little to no dirt visible, all roots, for years and years and years, no issues except more frequent watering is all. Every vegetating container plant will get root bound eventually aye? I've put those same rootbound plants in flower with no issues too, same container and all.. my outdoor garbage can grows are root bound too at the end of flower, and sometimes even in veg.
all the fuss about root bound drives me crazy. smaller plant containers make smaller yields I know. marijuana is happiest in large containers.
when I put a rootbound plant into a 60 day flower in a five pail it is not root bound at the end, does not produce as if I grew it in a five pail from the get go either.

I believe amount of light and the dry cycle and genetics determine yield in an indoor container garden.

And proper nutrition.

You will get no argument from me. I just want a healthy well developed rootball.

Use coco you won't run into root lock
I can go two weeks max on clones in solo cups before they start to rootlock in dirt. But coco is a different story. Faster more healthy vigorous growth. And clones only get bigger in cups with coco. It's confusing to the dirt grower but I recommend anyone trying coco. The results are unbelievable

agreed, those three resources can determine health and yield. but...a plant only grows to its weakest resource. All the light in the world wont help a plant with poor nutrition, as the biggest pot, best food, great genetics wont thrive in 125 degree temps etc.

now, as far as genetics. and proper controls, given all resources are provided correctly,
veg time will determine yield, aside from any training etc. stick two in veg, one for 8 weeks, one for 16 weeks, the 16 weeker veg will always supersede the yield of the 8 weeker in my exp.

my little critical + gives up a couple ounces with only a 6 week veg. My yield is directly related to every month added to that veg time, with a 12 week veg returning several more ounces, works with all of the genetics I've played with. again, assume all resources provided, pot size remains the same, more veg = more buds. (in my exp.)

my clones increase height daily in cups of dirt. roots are hanging six inches from the bottom of the cups before they get transplanted. usually 12 inches tall or so, but if I allow them to stay they'll get three times that height in the same cup, roots trailing

Sure that's what ya say but in all reality we know that's not true. Your dirt rootlocks clones in cups in 2 weeks or less in solo cups. I'll show you an example the next time I take clones. But if course your dirt is better than coco lol ok you got me. Oh and I'm sure your 100% at everything too lol @ that
