Phosphorous deficiency

More questions of course.

1. What would have built up in the soil to cause lockout? If I'm not using chem fertilizers then there should be no salt buildup, right?

2. If I flush, wont alot of the nutrients in the supersoil be flushed away leaving me with an even greater deficiency?

3. My other girls began to fade early. I guess that means I need to use more supersoil next time?

4. I still have 2-3 weeks left in flower. Would a small boost of chem ferts, like half strength, be detrimental? Will it kill thebmicroherd?

Thanks everyone for your help so far!
Post #13 Did you try it?
Yes you can add chem ferts,no harm.You maybe too far along to see much improvement.

1. Too much MG can cause imbalance.

2. A good drink of water may dilute any imbalance.

3. Coming into late flower fading of leaves shouldn't be a concern. It means the plant is taking nutrients from those leaves and using them.

4. I would use GH ripening formula. Bat Guano is always a go-to as well.

You can always try and fix these problems, sometimes it's best to just run with it. Get your crop out and get another one in. Sometimes things just happen and you can do more damage late in flower trying to fix things.

myke - I havent made it to the store yet, to look for those products (tomorrow!). I did give them a tea that I brewed with stuff that I had on hand, but I didnt notice any significant changes. I'm thinking of chopping her down tonight since the sugar leaves are now starting to go.

1. Ok, I could see that being possibility since my ro filters need a change.

2. I think I'm just going to chop her, she seems too far gone. I have two healthy clones of her anyway, for a second try.

3. I've never had plants fade so early. Then again, I always used chem nutrients, so I had control over that. These girls look like they should in week 8/9. I'll definitely be adding more base mix next time around and hopefully wont have this problem. I should mention that I vegged these girls a couple weeks longer than during the first attempt with NLS. I didnt have an early fade last time, so I presume that is part of the problem.

4. I'll be heading to the shop tomorrow and will look for both.

Everyone experiences fade with soil,you need to feed right around flip as the stretch uses lots of food.Fish hydrslate or similar can work quickly but Ive found dry amendments work in about 4-5 days.Feed the soil they say.

Well I'm not sure everyone. One of the reasons I went to "organic no-till" style was to avoid doing anything special for flower, other than cranking the lights up a bit and setting them to 12/12. I ensure they get all the water they can drink through the transition to flower and things come out okay.

I do agree however that an acute nutrient emergency in your cannabis grow is likely best solved by using chemical nutes. It takes awhile for organic sources of molecules to get mineralized by your soil life. In my no-till I'm generally thinking 1 cycle ahead. Anything I add in cycle #8 is really feeding cycle #9, and so on.
