First question. There is none ph range that you can put your finger on it and say there it is. 5.5-6.4. Best advice i can give is try to hit 5.8 when in vege. And rise the ph when they are starting to fatten the buds to a 6.2 or more it depends.I recently switched from soil to royal gold tupur coco so I wanted to reach out to the community to see if I can get a little help/guidance in this transition into using coco coir . I have three different strains(gelato mints, Biscotti, garanimals).
I use botanicare pure blend pro line, terpinator and fishsh!t. Feeding are based off the botanicare feed chart. Below I wanted to give as much info as possible to help get a better view. I received the strains as clones. So I followed the same step and process as I have done with soil in the past outside of adjust my ph from 6.4-6.5 to 5.9-6.0. I start at week 2 on the feeding chart for clones, now in week 5 the plants show signs of growth problems.
at week 5 of veg:
Room temp: 77-78F
Tested run off :
picture 1-2: Biscotte
picture 3-4: Garanimals
picture 5-7: gelato mints
Picture 8: Nutrients
What is the correct Ph range for coco?
How often should you water coco?
When testing run off, should I see a drop or increase in ppm and ph?
When using coco is run off a must?
Second. All the time it like hydro. To let the coco dry is a nono, because you can get ph fluctuations inside the coco. The coco fibers trap air, so the roots cant drown.
#3. Yes is a good ide to check the run off all the time. I use a notebook to write all about the growth. I put all i do in to notebook. Like the PH i put in and the PH on the run off to see how much nutrition they need and if there is fluctuations in anything. My setup is very cheap. I have two plates one smaller and one bigger. The smaller one i made holes in and put it upside down on the bigger plate. So this setup dont like PH fluctuations and i have gone through them all. If you are a fan of biology and what to put shit in the coco. I'm mean bat guano and and other shit. The plant reacts by building a big barrier of roots that can also fool you to think, that all is ok with the PH. So you have to also check how fast the nutrition solution goes through the coco. So what happend to me was that, when i poke the barrier with a long stick, my run off dropped to a 4.5. So i had a big salt build up on the roots. That i did not notice until a bit late.
