I fed them some Roots Organic Buddha Bloom yesterday (more than I typically do) to try to increase the phosphorus.

I also used a little SLF-100 enzymatic treatment at the suggestion of a friend to try to help the roots.

I added a heater at night to increase the night time temps.

I'll see how they do over the next week.

I've got some Optic foliar spray on order and some Hydroguard as well.

Not giving up on them yet.

The AN phosphoric is very strong. Out the bottle EC is 7-8 and EC is what burns, not pH. If you are using AN don’t spray below 0.5 pH

I have sprayed AN phosphoric acid on recently rooted clones at 0.5%. No problem. Maybe you had a problem with your water.

I will add that I have never applied more than this on cannabis. One grower contacted me and said he used 1% and added fulvic acid and it burned. Always test new things carefully folks!

RO water. I ain’t saying it don’t work...it does. I am just saying be careful. Exact numbers depend on a lot of factors. Under a pH of 0.5 I burned leaf on one grow but not another.

Total balance is what counts. And it is all over the map

At 0.5% AN phosphoric acid, the pH was 2.5 or so.

If you went to a pH of 0.5 you went way past 0.5% AN phosphoric acid. Any idea of how much you used to get to that pH?

So what I am saying is ANs quality control sucks. One gal ec is 6, next one is 8. Concept is good...damn few ways to spray P. Just saying AN sucks period. Protect yo self

Edit...and no I did not. The problem is their quality control, not mine. We did multiple repitisions

Night Time temp up to 63 last night with heater vs 58 without. Forgot to mention that I gave them a bit of CalMag as well.

Now I'll let them dry out over the week. Fingers crossed.

I'll try some of the Optic foliar spray on a few leaves once it arrives.

Also, as mentioned above, I did use a bit of SLF-100 enzymatic treatment yesterday for the roots.

What do you guys think of using Hydroguard to try to help the roots out as well - that should arrive in a few days?

Big question is - for next watering (likely near end of week) give just water or feed more Buddha Bloom as well.

Why not send in a soil sample and do this right?

The Buddha bloom has the correct proportions if you aren't drowning in potassium which I think you are. But without an analysis, we are all guessing.

Thanks for the suggestion but where do I send a soil sample for analysis?

I've noticed that the water drainage in my pots has worsened recently. My soil feels rock hard and 3 out of 4 of my plants take much longer than they should to dry out. I'm in FFOF with about 30% perilite. So I decided to "loosen things up" - I basically banged on the sides of the fabric pots with my hands quite vigorously - I feel like I was able to really loosen up the soil.

Man, the root balls on my plants are huge! - can they get rootbound in fabric pots? I'm in 3 gallon pots. Would it be completely lunatic to transplant to larger pots at this stage? (just starting wk 4 of flower).
