I seem to be having some ph issues with my first organic grow. Can anyone tell me how to raise my ph without killing off my microbes?

What is your water source? Typically I find that the gallon jugs of spring water or filtered water has a high ph of 8-9 - so you can try that method to raise your pH as a quick easy first step.

I'm using well water that typically is around 5.7-6.3

Just feed with pH 7 water until the pH gets to where you want it. If your runoff pH is less than 5, I recommend flushing with pH 7 water to bring it up quicker.

Hanging leaves (first couple)Das erste Blattpaar hängt leicht runter und sieht nicht fit aus. Liegt es an der Entfernung der Lampe? Gegossen habe ich 40ml jeden zweiten Tag nur als die Erde komplett trocken war bis 3cm tief. Luftfeuchtigkeit habe ich bei 65-80%. Bitte um Hilfe.:)Week 2

Plant starting to yellow too fastThe crystal meth has started going yellow very fast. The buds still have at least 2 weeks of growth needed to fatten out and pack the trichomes with thc.. I know it is normal to start dying but isn't this a bit early? Should I let her keep going as long as sugar leaves are alive?3 years ago

Too little calcium in early flower?I’m in the early weeks of flower and am seeing this happening. I thought it was due to an attempt at foliar feeding, but those initial problem leaves have been trimmed.
Is this a calcium deficiency, and if so, how can I address it?

What's going on with this leaf? Changed colors overnight?Woke up to find this leaf in the back of my tent. What's going on here? Day 46 flower. Recommended flowering of 60-70 days. Looking at my timeline, I figured I had maybe 1 or 2 more feedings left before I started giving just water till the end. Should I worry or is this normal?Leaves. Other

Dark spots on leaves formingSo this is two separate plants I've got brown spots forming at the top.
They're both about 4 weeks into flower. Watering every 3/4 days (4/5 litres each) with nutes. Humidity around 50% 26 degrees day time around 20 at night.
Any ideas?Leaves. Other

Seltsame Färbung einiger BlätterHallo zusammen!
Ich beobachte seit einiger Zeit eine recht eigenartige Färbung einiger weniger Blätter an meiner fetten Banane. Die Musterung beschränkt sich ausschließlich auf diese Bereiche, die Pflanze entwickelt sich sehr gut und zeigt keinerlei Mangelerscheinungen.Week 8
