Mr_Weeds_Autosanswered grow question 3y ago

I would start by checking your pH this being off can cause so many issues, I would also make sure that your watering to runoff to make sure there is not a nutrient lockout due to salt buildup, also at this stage, I would actually lower the humidity a 70% is pretty high for plants that are on week 4.

Sphagnum moss can by highly acidic. Since you are using a large percentage of it in your grow medium, I would be checking the pH of the run off as the first step to solving this issue. It is not a RH or PPFD issue.

Can anyone help identify this tox/deficiency?Week 6 I noticed that all the new growth has burnt tips I assumed this was a bit of a nitrogen toxicity problem since the leaves were all a nice dark green, no pale leaves were popping up. Also held back on feeds for a few weeks. Other forums said it’s normal but want to be sure.

Please take a look at the last photo of week 10, the close up of a cola. Does this appear to be the start of a K deficiency? There is tip burn on some of the plant as well. Refer to my notes with watering issues for past 2 weeks. All nutes listed ph ppm are correct. Thanks!!

My leaves on plant getting yellow at week 4. Gave her a flush for a few days with a pH of 6.0 but the run off stayed at 4.8. continued flushing with a high pH of 8.0 then the run off went down to 5.8. I did add peat moss to my Coco/perlite. Could that cause the pH to be low?
