I'm currently growing two strains outdoors: Jackflash #5 from Sensi and BlueBerry from DutchPassion (I'm a newbie...It's my second year of growing...only outdoors).
The soil is a mix of Compo Sana Universal potting soil (60%), Vermicompost (30%) and additional perlite (10%). The vases have great drainage due to the lower layer of pebbles I've added, protected by a fine mesh.
For plant food, I've only used powdered guano (about 50% more of the recommended dosage)...let it break down in the soil for about 2 weeks before transplanting the babies. The ratio for this guano is:
- 11% N (2.5% Amonia, 8.5% organic)
- 6% P
- 3.5% K
- 3% Mg
- 2% S
and...52% of "general organic matter".
They're both about 9 weeks in vegging. Now, as you can see on the following pics, My Jackflash is showing a lot of crispy/yellow lower leaves, and it's getting worse. The whole plant looks a bit pale as well.
I'm going only organic, can you guys help me diagnose what's going on with my baby?
A few additional notes:
They're LST'd, and when this problem started happening about 3 weeks ago, I've added a little bit more of the powdered guano...to no effect.

yellow leaves are first an indicate for to less Nitrogen.this can happen due several reasons first cause u just gave 50 percent of dosage of your fertilizer or the worser u gave too much water so this spoiled out any nutrients including the nitrogen which is the first defieciency u see on plants cause in veg, when u not overdose the dossage as written on fertilizer package u cannot give them to much nitrogen cause they need so a lot
anyway I would recommend u to give ur plants some roots stimulator that they can better take up the nutrient and for case of overwatering that they hurts can recover
cause u said ure a newbie I recommend u to have a look at this guide here
