Help please! Problems always start at 2 weeks with FFHF!

ilovereggae said:

For what its worth I think there was something wrong with the last bag of HF i got. Clones didnt burn they were just majorly stunted. I literally just pulled them last night and when looking at rootballs it was like roots had only grown on the outside of the pot. I had a few others that I just used OF for and those are doing fine. I am pretty sure I bought that bag off Amazon so figured maybe it was sitting in a warehouse for a long time or something and went bad?

I considered this, but I'm working out of two bags from two different sources.. so unless there's a problem at the Fox Farm source, it's probably my doing for this grow!

I personally pH my water just for the peace of mind and because it only takes a minute to do. I don't know how much perlite or castings actually affect the pH. What I was getting at was that adding all that increases your overall volume and that will cut back the ratio of the soil amendments (ph buffers) that help the soil stay within a certain pH range.

Well I can certainly do that, too. And that makes sense! At this point, I'm moving my PH with Ro water rather than any PH up or down solution (although I do have it at my disposal).

I'd try the RO water with some calmag added for now and see what happens. Water around the outside of the pot to force the roots to come get it!

About how much Cal Mag would you suggest?

5 ml per gallon

I have, yes. Here are the details: (I also have RO water at my disposal that I can cut it with to bring the mineral content and PH down, so that's an option if these numbers are too out of wack.

ph 7
hardness 332
tds 250
calcium 84
magnesium 30
potassium 5
sulfate 53
sodium 7
chloride 19
copper .01
manganese .17
Zinc .01
iron .28
electrical conductivity .49

That's good well water, use that.. forget the RO.

Feed em, get some Jack's classic 20-20-20 and feed em @ half strength.. give em a good soak and forget about em for a week.

Seems like a LOT of iron to me, but IDK if that could hurt anything...

Well that's good to hear. What would you thoughts be on still cutting it with about 50% RO water to bring the PH down. When I test it on my own, it's about 7.5. Also, I have purchased Nature's Living Auto Flower blend nutrients and plan on using them. So, I'm assuming just to go ahead with them once their ready for another drink? Thanks so much for your help!

We have a lot of iron and manganese. We had to get a whole house filter and water softener to save our appliances! It was pretty rough when we first put the well in. Obviously, I'm watering straight from the well.. no softened or filtered water for them.

My city tap water here in Chicago is 7.5.. never had any issues with growing in it. No need for the RO. You're overthinking this, just feed them and soak that pot good.. when it's dries out, soak em with tap water .. just alternate every time..

Do that til you harvest.

If it was supposed to be good for three weeks why did you add worm castings?
The soil was balanced to do something and changing it only messed it up. IMO. I use FFOF sometimes and it’s plain tap water no ph for about 4 weeks. Lower Ph tap water killed my seedlings one after another when I first started. Plain tap worked for me. Ph was about 8 or 9 I think

That’s not true at all. Earth Worm Castings won’t effect the PH, they even recommend adding EWC on the bag of Happy Frog.

Sounds like a plan. I suppose I figured that the plants would be fine until they were bigger without the feed. I'm still confused by the brown leaf tips, but I go ahead and get them fed this next time! Thanks!

That's good to know. I've read so many good things about worm castings... I couldn't imagine them causing problems!

I think your brown tips are just necrosis. The plant is pulling all the N out of the leaves starting at the tip. Once there is no more nutrients in the tips it starts to die.

This is of course after the yellowing has taken place for a few days or week. If the brown tips started first than I have no idea. I would feed it with a water soluble immediate nutrient. When I see problems like this I'll use neptunes harvest instead of a dry ammendment to get it fixed faster.

EWC or vermicompost kick ass. I like to add some pumice or lava rock in with it to add some aeration. I also like to mix other dry amendments with it depending on what I think the plants want. I can't believe people in the Organics section are dissing EWC, lol.
