First grow "Blueberry"... mmmmm

[MadSativa]

how are you testing the PH of the run-off? you really need a meter to test run-off accuratly... if you are using regular liquid indicator the test will be inccurate because your run-off water won;t be clear and will skew the results. It'll be tinted from the soil, nutes, etc.

assuming your test was accurate... puttnig in ph 7.2 water and getting 5.6 run-off would mean that your actual soil PH would probably be a high 4.x number which would be very acidic and would kill your plant for sure, so I think its safe to say that something is up with your test results

So the run off should be at a ph of or close to what you put in. is What you are sayin? Correct? and if it is not then when measured with a digital ph tester it is time to flush I asume. I dont grow but will be asking those that I do know what their measurements are in the runoff or waste.
I would think their would be a small differance in the feed water and the waste water

Soil= ProMix Nutes= foxfarm water at 6.5 ph 600 watt hps fun fun. The big ones are unidentified random seeds from a friend. Look like anything you may have seen?? They are 3.5 weeks old The little ones are DP Blueberry at 2 weeks. Have some strange brown on one of the berries, cant see in bad light, but it is in the first leaves and not the new growth...so.... the closeup is of Rating: 5

mad, the runoff pH reading will kinda give you an idea of what's going on in your pot. i can't even pretend to begin to tell you how. that's for the someone like rusty.

maybe he'll stop in. or start a new post calling for his help. he is a soil guru.

the plants are looking fine perp! be careful trying to diagnose deficiencies. this can really get you in a bind. with a pH of 6.5 you shouldn't have a magnesium or calcium deficiency. (unless maybe you have a salt build up or something).

maybe if your pH is really 5.6 then you might start to have a problem.

a transplant and the fresh soil will help if you do have a pH issue with your (hopeful) ladies.

keep up the good work!

Thanx for all the help. One of the big plants seems to have a serious magnesium deficiency, i think i might have over fertilized her so i flushed her with some 6.5 water to get any salt buildup out of the soil. I fed her nutes 2 times in a row and have learned that fox farm has bad salt buildup and you are supposed to nute every other feeding. ugh.

Thoughts?

i have just started the using the FF line up so i can't comment from personal experience. but i have read around here that people prefer to feed them 1/2 strength nutes twice a week (so still a full dosage) because they run a little "hot".

i've also been advised to flush them on about a once a month basis.

keep up the good work!

I have been giving them half strength like you said, is good advice. Still got this problem on the leaves though... still trying to figure out what it is. I flushed them with plain water to stop whats happening (hopefully). was going to put them into flower this week but looks like i cant till i straighten this issue out.

hey perp, i read on one of these logs, although i can't find it at the moment, that one of the different breeders blueberry strains is kinda a pain in the ass. i'll keep trying to find it to see if it was the DP version.

did you post in the plant problems section? and fill out the troubleshooting form (in my sig).

someone with more knowledge/experience than i will surely stop in and give the appropriate advice.

Promising read He didint have the problems i'm having with the nutes.. my thumb is brown i guess. He did an awesome job.:jointsmile:

will update with pics , i think i have the problem under control. flushed with water.. i guess i over fed them nutes.
first pic is my lil cloning machine with the bag seed clones and some clones from a g13 cross i got from secondary
2nd pic is the g13 i will keep as a mom for now,
3 pic is one of my blueberries stem.. fan blows on them all day every day.
next pic is field of blueberries
i over ferted the bb's a lil.... curling leaf tips and very slight nute burn. makes no sense cause i'm using half strength nutes! damn these brown thumbs!!!
