you might look at the amount of water your using..

If it's lockout rather than a nutrient deficiency, whatever the plants needs most of at that moment in it's development, is what is going to show up as a nutrient deficiency. In late vegging to early flowering, the plant needs more magnesium and phosphorus. Low temperatures can also lockout magnesium.

you mean magnesium toxicity or magnesium deficiency?
thanks for the valuable information, great to know those things.
sry for my noobish questions. im in my third-ever grow and still learning. growing weed is a whole science. but sooo much fun in the same time!

yeah, i definitly overwatered the plants earlier. but since i started to use less amount of water the plants are looking much better. not perfect yet tho..

I'm glad Tanzanian jumped first. I was sitting in the middle of N/Mg. Typically if your N is toxic either as ammonium or nitrate, the curling is infinitely worse. The explanation I've read on this is that the tissue is growing faster than the veins. Thus it looks like a bulbous burn victim lol. In your case, I saw that curling but it's nowhere near bad enough.

Look into calcium chloride or calcium sulphate. The calcium sulphate is immediately available- not sure about the chloride. And as your plants are recovering use any remedy in smaller amounts to begin with so as not to choke the whole thing if we're wrong.

A foliar Ca like Albion, Baicor etc. would help a lot. I wouldn't apply calcium chloride on the soil. Foliar calcium chloride works well too!

If you spray Mg foliarly, it will help the plant shed some of that N.

No problem at all, I'm still learning too after 14 grows and will for the next 14 too.

They're not getting enough magnesium. So whether they just need more, or whether nurients are locked out because of low temperatures or overwatering will determine that.

Just to add, the photos don't show it clearly, however if the pots are on the ground, that would likely be too cold for the roots, especially this time of year. This could lock out the magnesium and all that would be required would be to put the pots on a bench or even a folded crate. Just so there is some space between the pots and the floor.

When nutrients are locked out, they just stay in the medium, which can lead to toxic buildups when they do become available again.

I've read many books, however two books I've absorbed over the years, are:

The Marijuana Garden Saver, by Ed Rosenthal.

Just to memorize and re-read all the plant nutrient deficiencies and insect attack and fungal outbreaks.

True Living Organics, by The Rev

For all the descriptions of natural products, their applications and where to find nutrients in organic materials. He basically works with a version of Supersoil, and adds reservoirs and mulch layers, which I'm expanding upon in my own grows. There is a second edition out.

i have started foliar feeding cal-mag and also adding it to the water. the plants have responded really well to it!

thanks for the reply tanza! the pots do stand on the floor. but it is an insulated wooden floor so its pritty warm, not like a cold concrete floor. i will definitly have a look on the books.

OK ladies and gentlemen ! now that i got your attention
its time to mix up a soil to use on the next grow. this is the ingredients i have at hand.

i will insert images so you can se exactly whats in the stuff.
top soil

cow manure

worm castings

chicken manure

[ganjamann1]

bone meal

blood meal

fine ground lime (powdery)

large ground lime (almost like pellets)

[ganjamann1]

This is the stuff i got in hand, i also have bat guanu, perlite and epsom salt. but forgot to take any pics. anybody got a good recepie on how i should mix this? what ratios, in gallons or Liters. doesnt matters. lets say i want to mix a total of 100 liters (25 gallons)

my last mix did not turn out the way i wanted. too hot. thats why i turn to you experts, i know we got some real skilled growers around here.
