too much thrive alive?

[budman678]

i transplanted 5 week vegged 2 gal plants into 5 gallons about 45days ago. i used thrive alive and cal/mag after i switched them to larger containers...ever since then, i have used thrive alive and cal/mag at full strength everytime i have feed/water since.

today:
they are at 24day of 12/12 and one of the three is getting some yellow/nectroic (small brown spots) on the lower fans leaves. i have been feeding with grow/bloom/hpk from roots organic ever since flipping the light in conjunction with the thrive and cal/mag.

is it possible i have too much cal/mag or thive and its making my girls sick?

i can't post pics for security reasons. but can answer any questions asked.

***i know this ia not ideal and pics are king but please help me knowing that i am unable to post pocs***

thrive alive isn't really meant as a base nutrient, its possible they're exhibiting deficiencies of micros/macros not included in great enough numbers.

Are you feeding anything else?

**edit**
technaflora doesn't recommend it as a standalone nutrient, http://www.technaflora.com/indexProduct.php?ID=107 it does have a small NPK rating, but they likely don't have a full pack of micros in there.

this is my feeding regiment:

Roots Organic grow
RO Bloom
Roots HPK
Earth Juice Catalyst
Cal/mag
Thrive alive

last feeding was around 650 ppm with ph water of 6.4

runoff has been btw 6.3 and 6.5

 

[RubeGoldberg]

sorry, i didnt read closely enough on the first post to see the other nutes you were running.

how much of that 650ppm is from the calmg?

 

[budman678]

cal/mag that is a very good question. i would say not a signicant amount i am following the feeding schedule to a "T" from their website. obvs i am backing off if its too much.

i am just curious if i should drop the cal/mag (maybe too much is hurting them) or cut the thrive? im just not sure where to go...its early on but i know it will get worse if i cant address it. i am going to let the soil dry really good and the next feeding will be everything but drop the thrive and cal/mag

 

[RubeGoldberg]

I don't think either are the issue, however it won't hurt to cut them back for the time being.

What are you using to measure the PH outta curiosity?

You're not really feeding at a super high rate, your nutrients should have everything the plants are wanting and they should be available at the range they're going in, especially if the runoff what you say it is. So it doesn't seem to be overfeeding or some kind of lockout unless the meter is fucked.

What are room temps looking like? Anything crawling in the soil?

 

[budman678]

the occasional gnat...occasional as in i might see one once every two weeks. not an issue..

which brings me to temps....
75-83f

not ideal but there is plenty of air movement it has just been particularly hot. in a 3x3 tent with a 200cfm pulling through a 4x12 phresh and a 400hps ballast. one 6inch air king shooting at the space between canopy and light. and an oscillating floor fan for under the canopoy... plenty of air flow...higher than i would like temps....hoping it cools down soon

 

[RubeGoldberg]

aside from the temps being a little high it doesn't seem like you have too much that could be going wrong in there.

Again, never rule out the meter, never hurts to have litmus paper bouncing around so that you can test your tapwater against the meter as an extra level of redundancy every so often.


Also you mention PPMs, In organics I'm not the biggest fan of that because the organic material in the nutes can play around with that.

based on their feeding schedule, are your amounts of nutes per gallon pretty close to their recommendations?

 

[budman678]

i am going to recalibrate the meter this afternoon. it is a nice ecotest digital meter.

i am following the feeding schedule to a T....except that i dont ever just water. i have ALWAYS been feeding nutes. every single time.

[RubeGoldberg]

What kind of soil are they in?

I'm not an organics expert so hopefully someone chimes in, typically nute buildup with synthetics will show up as a huge PH difference on the runoff.
However not sure if this rule applies with organics. But since you've been feeding with every watering it may be something to consider.

i am using FFHappy Frog and 20% perilite. they have been doing great until now...

is it out of the question for a few leaves to yellow (only on one plant right now) at day 25 of flowering. keep in mind they are really packing on weight right now...the stretch has slowed down or stopped

Naw, not outta the question at all. The plant will decide to get rid of some leaves from time to time. Not uncommon at the peak of flowering.
But it depends on the type of yellowing and how bad, how many leaves etc.


Did you start feeding the happy frog straight from the get go? or did the young plants have some time to use up the amendments in there?

 

[budman678]

when i transplanted i just watered with ph...and but after that i have fed non stop?

i am thinking maybe that i am not feeding enough?! is that a possibility

 

[budman678]

i wish i could post a pic but i cant.

maybe i can find one off google images!!!!stay tuned

 

[RubeGoldberg]

I think you're maybe feeding too much and causing a lockout. I'd have at least one ph adjusted watering per week without food and a bit of runoff. Don't think they're currently being under fed.

pics in the morning...thanks for all your help

 

[budman678]

this is a crappy cell pic but i think it will give you a pretty good idea of whats going on with one of my ladies..this was right before the hps turned on
