All you had to do was dim it or raise it higher. If not dimmable then distance to reduce intensity is only way to solve it.

Really doesn’t look like light burn to me. Especially running blurples. They are not especially intense. I think you have some feeding / pH issue possibly - if anything.

Is this heat light burn? HPS 600w at 20cm
Is this light heat burn?? These are all buds at the top of the canopy and they are the ones nearer to the lights. I have 2x600w HPS, one with a cooltube and the other just with the wing. The possibly burnt buds are the ones under the wing (just 20 cm).

What is that?
Yesterday evening feed 0.5 litre EC 1400 pH 5.9. Runoff was EC 900 pH5.6 Increased light intensity to PPFD 600. This morning larger upper leaves are in "praying" position, one leaf closer to bottom looks sick. If it's a light burn, why not on upper leaves?

Light stress?? Wilting leaves, shrivelled and burnt edges. See pics in last week.
Any idea what’s going on? Leaves are shriveled and wilting, as well as some burning at the edges? I’m guessing this is from light burn/stress as I’ve only watered and used very very little nuts so far. Lights were at 22 but now at 30. Temp is 24 w lights on, 55 humidity. C pics.

Suggestions as to why this plant is a mess!
First grow - Blueberry Auto outdoor. Pathetic thing is on day 36 from direct sow. White splotches since week 2. Subjected to excessive heat, an oversized garden bed, lack of sunlight and overcompensating with supplemental grow lights. CoM organic nute/soil. Any solid diagnoses?

Help! Why are my leaves turning yellow?
Not sure why some of her leaves are yellowing on the edges. Is this due to environment? - 78.3°F | 64.8%RH Or a watering issue? - Currently she's drinking 8-9 cups a day through a sub-irrigated planter (EarthBox). Or maybe a deficiency? - See Logs for complete details.

My leaves are getting brown/yellow, I saw online that it's a bad sign but I don't understand if it's under watering, overfeeding, underfeeding, light burn ecc? Thank you so much for the help first time grower.
