wouldnt be in a rush to go hydro if you get a hydro grow wrong you can lose the lot very quickly press on with the soil you will learn so much with a little persiverance.

Im sure this has been covered but you need to mix your soil with vermiculite and pearlite to losen the soil, provide air and hold moisture. Oh and 6.5 PH is a little high I prefer 6.0 - 6.2 for ganja.

-------False------If The soil run-off is 6.7 and he's input water pH is 6.6 then he would still be under 7 not over. As far as the ideal pH for soil and marijuana that allows all major and minor plus micros to be available and assimilated in a non-chelated form----it's a 6.575 pH.

Wrong. To lower the acidity of something by .1 you need a pH difference of at LEAST 1, or greater, in a 1:1 molar solute. That means the soil HAS TO BE MORE BASIC, and NOT in such a narrow range of acidity, to make runoff that acidity.
That means if his water is 6.6 and his runoff is 6.7 his soil's likely around 7.5+ and that's what has been causing his problems all along. BAD PH.

You are correct about the movement of PH and the required balance of basic/acidic correction for a 1:1 molar solution, But incorrect as to his soil being over 7---There are too many variables in the soil and in the application of balancing solution along with time and saturation to say that his soil is over 7 because he started with 6.6 and his run-off said 6.7. I would put my money were my mouth is and even go on to say that if he added a 7ph solution to the soil then run-off would read at or below 7PH---The reason he is showing micro nute deficiencies is that those nutrients become locked-out above 6.6----As you already know--you don't have to be above a 7 PH to experience micro defs. Not trying to be rude or a know-it-all but I work with soil day in and day out along with testing run-offs and direct soil testing.

not so good a few days ago i transplanted some of my plants in coco coir i heeded your advice and fed them 6.3ph water, to some of the bigger plants i gave a 1/4strenght nute solution to see how that goes and i got 3 afghani's from sensi that i planted in some new soil so far theyr ok but im waiting to see what happens in 10 days thats the critical period

these are the afghani from sensi 7 days old planted in the new soil
heres the link of the soil www.agriferma.ro/pdf/substrat/substrate_tc1.pdf

The DP looks like it is struggling a little but the white russion looks good----your seedlings look good as well. You may have to to just wait the DP out a couple days---sometime's they take a little time to rebound after stress.

How long between transplants?

I agree that the first issues were lack of oxygen and soil too compact. I know some growers have had good grows with slightly above 6.2 PH but you should try and drop that down to 6 or 5.9 and you could get better results? Just what I have read. I had similiar issue as you and making the ph 5.8 fixed it right up the same day as the watering and I am in 100% miracle grow soil
( Planted them before I read up ) but both plants are thriving as I think the other issue was how much you were watering them at once. Over watering is hard to do with adult plants but seedlings like yours maybe tuning down the amount and increasing the frequency, along with mixing up the top 1/2 inch of soil to aerate it better is good for 100% soil plants. Water fresh water every time and you will never have to aerate watering solution unless of course you have a permanent water feed system.
The coco-coir you have is same stuff I got. The water drainage is 100% improved from what those guys were in before and it is HARD to over water plants in a hydro medium. You really have to be drowning them. Most hydro mediums have zero nutes. be careful not to have your coco coir not mixed and compacted, this can also cause some soil-like compact conditions. Try mixing anything that is stable and not readily water soluable like perlite and mix that with your coir, will work wonders! I am going to try 2 different sets myself, I have aquarium safe rocks that I will be trying as a mix with coir and also perlite, to see which does better. Would like to hear from your results as well!
Also I think I read someone said to not be nuteing soil plants at seedling stage, this is generally a great idea unless you want some unecessary worrying and some burn as the light and the nutes in the soil will feed that sucker for a good few with just normal ph adjusted, dechlorinated tap water.
As for random plants going, it could be genetics. With a bad start like they had easily a plant can be weak enough genetically to only grow to a certain point and die or just die right away. Transplants are alot of stress too especially from soil to coir if you removed all of the soil from the plant before the transplant its like taking a person from a thriving market and putting them into poverty, they arent used to it! Deaths can and will occur!
