Yes my bad, i wrote down the RH from light level, i just put a hygrometer ag canopy level and it reads 67%. Im using a dehu to get it down so i could stil raise it a bit. Thank you ---

Would these things lower thr PH ? ---

Worm castings are entirely the problem IF nothing else is present. Top-dressing dolomitic lime is probably the best thing besides transplanting into cannabis-optimized soil. There are people that grow successfully in Miracle Gro too but a new grower should NEVER use MG. Same for soil; donā€™t build anything that you canā€™t get commercially already (like FFOF or Roots Organics etc). Iā€™m an experienced grower and I would never commit to growing cannabis in that mix. Itā€™s just asking for trouble. ---

I dont think i mentioned that before but i also ad mycorhizae with every transplant and i use the full line from Remo nutrients. So just leave the wormcastings out for the next transplant? Maybe 70%coco and 30%perlite ? I like coco because its really hard to over water. Thanks ---

After one day the coco is still really wet, can i still water? Thanks ---

> [@Spiney\_norman](#): > > then watch Gilligans Island Mary Ann, Ginger or OH NO Lovey? Old habits are hard to break. Iā€™ll still check runoff. Probably more often than I need to. Jackā€™s & coco - pH is 5.8 - 5.9. ppm is more interesting. Usually in 1400 - 1600 range. Will spike to 2000 occasionally. ---

Yes: coco/perlite is _soilless_ and you have to provide all supplements. Coco does need to remain damp to wet. I have gone a couple of days between waterings when the plant is too small to uptake all of the water in the pot daily. If growing photoperiod Iā€™d recommend potting up a couple of times to avoid overwatering anyway. Autos, not so much. ---

I donā€™t really know what your definition of really wet is, but yes I feed daily without checking how wet my pots are in coco. I would say itā€™s noticeably dryer after 24 hours though. Are you feeding around the time lights come on? ---

Its more moist not really wet, no matter how much i water it never gets as soaking wet as soil. I try to water when the lights turn on but its not always possible. (Due to working shifts) ---

work outside the home is a great reason NOT to use a highly interactive grow medium such as Coir. Itā€™s a great way to grow as others mention above for maximum control but to maintain that control demands consistent daily attention. ---

You definitely donā€™t want to allow it to dry out completely. Coco will become hydrophobic if you do. The easiest way for most to deal with is have lights come on at a time you are typically around. I usually have mine come on 9-10pm specifically for this reason. ---

> [@MH47](#): > > demands consistent daily attention There are any number of automatic watering systems out there for not much $$. Blumat is one IIRC. ---

Is there any runoff with these systems ? People usually tell me to water with runoff in coco. ---

I didnā€™t water to runoff the last few grows: autopots. Thereā€™s another way to make things easy and thereā€™s any number of growers with journals on them. I can go 5 days without touching anything for 3 plants with the reservoir supplied. If you use Jackā€™s and either top-feed on a timer (blumat) or bottom-feed like with autopots, the need to water to runoff goes away. Do some research: search this forum and read some journals. ---

Good point. If you have the budget auto watering could be a solution. Given the experience level of the grower, not checking the plants for days at a time might not be conducive to catching a potential issue early. A more experienced grower could probably relax with auto watering and treat them like a houseplant. ---

> [@Myfriendis410](#): > > If growing photoperiod Iā€™d recommend potting up a couple of times I do this by setting the 1 gallon fabric pot into a 5 gallon fabric pot. The roots grow right through the felt and you donā€™t have to mess with removing the root ball from the smaller pot. You can see the original was set about 2 inches into the larger container which I removed for the photo. Massive roots grew right through the first pot and the plant thrived. ![20210622_125336](https://global.discourse-cdn.com/growingmarijuana/original/4X/3/8/5/3852638a937a01cc9dc37c512d2892aaeb150d22.jpeg) [Previous page](https://ilgmforum.com/t/ph-to-high-in-my-coco-runoff/77494.md?page=1) [Next page](https://ilgmforum.com/t/ph-to-high-in-my-coco-runoff/77494.md?page=3)
