First Ever Grow.....Jack Herer Auto from ILGM in FFOF under HLG 600R light , average temp 75* with RH around 55% Everything has been pretty smooth until now . Feeding GoldLeaf fertilizer every other watering......if anyone can tell me what the heck I've done wrong.

PH @ watering is 6.4- 6.6 and run off is 6.8. Much appreciate any feedback

I just had the same pop up. Mine was in week 6 of flower on a photo period strain, not auto flower. I came up with manganese deficiency...... not sure if I am right or wrong but just decided to ride it out. Might of also been something to do with high humidity. My dehum crapped and had to be replaced so it got to 70% for a couple of days..... any input from others would be great?

what are your measurements in ml per gallon of food that your feeding?
during flowering the plants needs are constantly changing, so deficiencies are either calcium or magnesium that are usually getting lockout.
your light could be part of it too.

Yeah, looks like a combination of heat stress and overfeeding. Not significant, but enough to be locking something out.

Those are getting burnt by the light. I'm new to LEDs and I'm seeing a bit of burned leaf teeth.

Some strains are less susceptible, but on the same plant you should see the buds closest to the light with the most damage, buds further away or partly shaded will look normal.

Thanks everyone for the replies I'm gonna raise the lights up and see how it goes

What’s your runoff ec? Looks like a nute toxicity

I had thought so also but wasn't sure. Unfortunately I don't have a meter to measure

Go out and buy a blue labs soil tester when you can. If the water going in is 6.4 and the run off is 6.8 your medium may be over 7.0. Which could run you into some lockout. I would say any where from 5.8 - 6.8 is a good range and I’ve only seen deficiencies when above or below that range. In my experience most deficiencies can be solved by correct medium and water ph.
