Biocanna bioterra plus correct Ph, nutrient defeciency

[freedom420]

Hello everyone, i am using this soil for my first grow and i am having serious yellowing of the leaves alongside with brown spots and dried up leaves. The plant is 68 days old and 4 weeks into flowering. My problem is that i don't know at what Ph to water as the "soil" consist of coco, peat and bark. When i started feeding and watering at 5.8-6.0 Ph problems started becoming more serious, before i did so the plant was just a little light green and that was all, now it is almost dying.
I feed with biobizz grow and bloom, 4ml each and palm tree ash which i will stop as it might negatively affect the ph of the soil. I also have top dressed with bat guano and cal/mag pellets.
Any help will be much appreciated , thx

Welcome to AFN
Well they look like they're too wet.
And need to dry out a bit.
Real pale and droopy.

Honestly, they were worse and i tried to water more often hoping to fix the issue but it didn't work. Any tips on feeding and Ph? I am looking up allover the internet in order to find the correct Ph for my soil but cannot find any info.
The plant looks like that with the soil bone dry atm.
Current situation after heavy defoliation of burned leaves.

cal mag pellets? hmmmm


palm tree ash has a ph over 10 so you may have a lockout.. otherwise it just looks sad and hungry. ide do a plain watering to 25% runoff & check ppm & ph of runoff asap. report back..
Youre kinda doing a coco grow with that mix youre using, so not sure you should be letting your medium dry out.. but Im a organic soil guy so I am not totally sure about that... hopefully someone with more experience with this style will chime in.

Thx, last time i checked runoff was 7.1 Ph. The mix i am feeding though is Ph-ed down to 5.8-6.2.

thats odd... are you feeding every watering generally?

 

[freedom420]

no i was feeding weekly and watering every fourth day or so when the medium got dry. the problem is either the Ph or the palm tree ash. Fot half the grow i didn't manage the Ph and the plant was healthy. After i started doing so the plant got sick. I will not feed any more ash as it is not needed but i have to decide at what Ph i should be watering, cos i have one more bag of this soil and one more plant already growing in it.

I think you need to feed every watering with this product... maybe at a lower dose like half of what youre using, but every watering. PLants might just be hungry.. According to this biobiz guy you dont need to ph. Make sure you water them really well when you do. Does this mix drain very well?

 

[freedom420]

nice, i didn;t know that. But at what Ph should i water?

This guy has other videos and says not to ph... So Im guessing the bottles are buffered? Check my previous comment I added to it
Ide feed at 1/2 -3/4th strength right away.
