Forbidden runtz excess or deficiency problems autoflower
BAD WEEK! need some help here guys.. Brown / rust spots started to appear on the tips and slowly started yellowing leaves. Im following the master advanced nutrients chart and watering 2 times a week. Last week feed was 20 litres R/O water 80ml bloom A 80ml bloom B 40ml of every additive on the chart 20ml cal meg 30ml phup PH adjusted 6.50 After i started noticing the brown spots / leaves curlin up and stunted growth i skipped a feed and flushed with plain R/O water used 30 litres for 4 auto plants. Yesterday i watered again but cut the nutes in half. 20 litres R/O water 40ml bloom A 40ml bloom B 20ml of every additive on the chart 20ml cal meg 20ml phup PH adjusted 6.50 I still don't know what the problem is, if it is a excess of something or a deficiency..Looks like a cal meg deficiency but ive beed using cal meg since the beginning. Maybe i have excess nutes in the soil and resulted in nutrients lockout of cal meg or something else? since i water twice weekly should i water with nutes always ? The master advanced nutrients chart still sometimes confuses me. Please any help will be appreciated

Too Much Light?
This plant got a light upgrade. And then this happened. I think the light was too intense. So I raised it up and turned the dimmer down to 75%. Asking to avoid this issue in the future.

Leaves tips look burned
Any suggestion of how could make her look healthier? Tips look burnt and leave color is not great. Also my plant is very short, 25cm. I didn't feed her any nutrients so far, only water pH6.5. The soil (atami kilomix) was heavy fertilized with bat guano. Is she needing something?

I found out my tap water was 9.8. I'm about to water tomorrow with PH adjusted water, I just didn't know whether or not that could be the issue with the tips turning yellow? Bigger plant now too,just not as bad Basically will the soil adjust since it's a premix in between 6.3-6.8
