Corrección de Ph?
Horseluisweedstarted grow question 5y ago
I’ve covered it with coco and watered with about 80ml mixed with coffee grounds, it’s an experiment just like the grow, the substrate is a mix of equal parts coco (6ph), hummus (7ph), and vermiculite (8ph), assuming a pH of 7, we’re trying to lower the pH with this maneuver.

If you want to lower the pH, you can let the water sit for a few hours, it usually works really well :)

Coffee grounds are good for cannabis but even better when you compost it first thru a compost or vermicompost

By the way, it's day 13 since the sprout, should I remove the coffee grounds from the substrate? I don't want mold to grow, but I read that it's a good home remedy to slightly lower the pH (put a layer of coffee grounds and water).

Yellow leaves on nearing end auto.So we are nearing the end. Now there seems to be a lot of conflicting information out there on yellowing of leaves at this time. Some say it’s fine some say it could be hungry or lock. The bud still seem to be growing so not to sure what to do. I stopped feeding about 5 days ago.

Help with lockout of deficiencies. Don’t know what to do from here I already flushed em but doesn’t seem they uptake anymoreNeut lockout/Deficiency? I was watering less more frequently in fabric pots. I believe it created a lockout in the 3 taller plants by not allowing more run off of water. Correct me if I’m wrong there but what do I do now? They are not looking well and now the leaves are curling

Leaf burnt edgesOne leaf has burnt edges and is a little different looking, than the other leaves. Is this some kind of nutrient burn? I am using a light mix soil, and have not fed the plant with additional nutrients, except for a little root stimulant (half of recommenced dosage).

Should I flush? (Overfeeding)I think I have overfed my 2 dwarfs. Theyre showing signs like very stringy skinny new growth and yellow leaf tips. Theyre still growing and I dont want to stunt their growth, so all I want to know is if it is necessary to flush. Please tell me how to flush if so, thank you.

Hungry? N deficiency?So this sort of just happened overnight. Plants were very thirsty this morning and noticed a handful of leaves that are fading.
I fed them 1tbs of dr earths flower girl and 4ml of calmag in a gallon split between the 2. Should I add some of their 4-4-4 as well?

Recurring Cal Mag issuesI’m already at the maximum recommended cal mag dose of 1ml/litre (with nutes at 1000ppm or E.C. 2.0) and I’m still facing issues.
It went away for a few days, but it’s now back.
Should increase the cal mag dose and cut back on the macro nutes to maintain 1000ppm?
