Seed: ILGM sour diesel auto
Soil: Fox Farms Ocean Forest
Pot: 2 gallon fabric
Light: Mars Hydro TS1000
Water: First four weeks was tap water and would use Ph down to get it to around 6.5. Subsequent weeks: bottled spring water
Nutes: None
I’m in week 6 for these plants. For the first few weeks, everything seemed to be going fine with the plant. They were growing at a good rate and the leaves looked healthy.
Around week 4, brown spots started appearing on some leaves. Also at the start of week 4, I realized the Ph of the water, after sitting for a day or two, was climbing back to around 8 after Phing it to around 6-6.5. So, there were likely several times when I gave the plant water that was way too high in Ph. Starting in week 4, I would get the water to an appropriate Ph (6.3-6.5) level and water the plant immediately.
But the brown spots on leaves continued, and some leaves started turning yellow and were dying. Some stems were purple/red.
At the start of week 5, I decided to switch to bottled spring water, thinking the tap water may have been part of the problem (chlorine, chloramine, etc.) The spring water happens to be at a good Ph, around 6.5.
But the issues persist. At first I was thinking it was a deficiency since I have not given them any nutes, but new growth has burnt leaf tips. So I’m a little confused how this could be nute burn, and if it is, why there was no signs of it during the first few weeks.
Throughout the grow, I’ve occasionally checked the runoff after watering, and it’s around a Ph of 6.
