Thanks. Just to be clear, I only watered them with plain water once after transplanting, and only because I thought they had nutrient burn and thus followed the advice of an article to flush with plain water. Obviously this was not the correct approach, so lesson learned there.
I have a bottle...
They seem to be doing much better, thanks. I haven’t had a chance to read the pH meter manual and get it calibrated (on the schedule for today) so I’ve still been using the GH indicator solution. I’ve added just a smidge more of the pH Down after mixing the nutrients into my water, so I’m...
Thanks for sharing your grow journal, those autos look great! I will definitely stick with coco until I can get it right (hopefully I can turn around this first grow). I have some Seedsman auto kush, so after this grow I'll give those a go.
Also, I ordered an Apera pH meter today, so I'm...
I appreciate this info, thank you. I read up on buffering and cation exchange and it makes perfect sense. I will get that pH lowered and continue to supplement with cal mag.
Hey man, if I had this figured out I wouldn’t be in Newbie Central looking for help. You seemed to imply that I was pulling the 6.5 pH for coco out of my ass so I provided where I found that info, that’s all. I’m here to learn from my mistakes, not argue about something I know very little about...
I will look into the calmag issues. FYI, 6.5 is just my high-end guesstimate since I'm using the color chart on a General Hydroponics indicator solution bottle, so it may be a bit lower but it's in the yellow range. Guess I need a pH pen.
Also, while cocoforcannabis recommends a max pH of 6.3...
Sure did, on this forum, the site you linked, and growweedeasy. The problem is that they all differ in the information they provide so it’s a bit of a guessing game and then ending up here seeking additional guidance.
I transplanted from solo cups to 1 gallon fabric pots on 12/22. I also moved the plants into their grow tent under a 315 CMH with a fan blowing over them. The next day I had some brown spots on the first set of leaves, which I attributed to nutrient burn since I think I gave them too much...
These girls are almost two weeks old from planting. They are in Jiffy pellets in coco medium. I made a lighting mistake early and they stretched. They’ve been growing slower than expected but they are growing. There were a couple roots growing out the bottoms of the cups but I air pruned them...
