Nute burn or light burn?

[GenieMan]

I been giving my plant 1 and a half teaspoon on Tiger Bloom once a week in a 1.3 gallon Vivosun watering base. To much? I was going to give only 1 teaspoon this upcoming week. I also keep the base topped off with water. Unfortunately I can't move my light higher I can lower the intensity but my lower bud loose alot of light so not sure what to? The leaves that have those brown spots are father down too which leaves me to believe nute burn? Idk. Figured someone would of had a similar problem. My also tested my ph of the base and it was 5.6. Humidity around 50 and temps around mid 70's.

It looks like you are experiencing a little bit of everything, plant senescence, the plant is drawing on energy in the leaves, minor nute tip burn, and light stress.. or led light burn ..i have not tried it but i have heard that introducing Co2 helps the plant deal with all these stresses for the last 4 weeks.

Thanks for the reply. I took the plant off the older base and switched it with a whole new one with straight water. I guess I'll push straight water for a 2 days or so then put in 1 teaspoon of the tiger bloom. Not sure about the led though cause half way down the main cola I'm getting DLI of around 40 which is max for non c02. Id hate to lower the intensity for just the top half. ( choices lol ) and the natural yellowing is nothing I can do anything about obviously ah well.
