Soft hanging yellow leaves, some with brown spots in the middle. Deficiency, Nutrient Burn or what could cause this ?
Hey guys, I got a problem with two of my 4 plants. They started to develop yellow droopy and soft leaves that start to fall off on their own. I’m not sure if it’s a nutrient deficiency or blockout from ph or something else. I watered them only with water ph 6.5.

Does yellow leaves with red tips mean my plants need more nutrients or less? Jacks 3 2 1 on Auto
Week 8 (flower) top leaf tips are reddish and the leaves are more yellow than green. Does this mean that my plants need more nutrition? I am using Jacks 3 2 1 for two autos and using it at 65% strength (650PPM / 1.2EC). Should I goto 100% at 990PPM / 1.9EC or 50% to 550PPM/1EC

Northern lights with yellowing leaves
Hey Guys, my NL is starting to have some issues. I started off with the leaves just laying low, i've eliminated lack and excess water, and it's not temperature related. I did a small flush 3 days ago and things got worse. What do you guys think?

I'm not experience in growing and this is my first plant. I'm still worried by the yellows of young shoots. Can someone help me recognize the problem ? 🙏 All suggestions will be valuable. 👍

I have about 3 weeks left of flower, haven’t started flushing and had some deficiency in the beginning. The yellowing is starting to creep up to the smaller, upper leaves. I’m thinking a cal mag issue since I have not supplemented with that at all. Is it too late to give ?

Is this magnesium deficiency?
After some googling, it seems to match? But the yellowing on mine seems to be very concentrated just on the tips.

Purpling, contorting, drying, yellowing.
Leaves are going all nuts, i think it was from a bad feeding, i've been too busy, no time for notes, they started going purple after feeding so i used plain water for the next 3 waterings with +water, tops started showing calcium lack, anyone can confirm? Give bloom+cal right?thx

Yellowing leaves
Hey fam, Just ended 3 weeks of flower for this Banana Purple Punch Auto. A heap of yellow leaves basically appeared over night. I fed on the 13th with flower fert (has some N in it) and again on the 18th. This is the only plant that’s going yellow. What do you think?

We've had some really warm weather the past few days. This morning, just before the lights switched off, i saw it was 31.1 degrees C in the grow tent. Are the yellowing leaves a concern? The yellowest leaves are really brittle. I don't believe they're under-waterd.

Do I have a deficiency problem or am I ok? 3 lower leaves on both plants started with the tips browning but now the leaves are going yellow. None of the newer growth has been affected but the 3 leaves seem to be getting worse. See pics in week 4!

Defoliate lack-of-water damaged leaves?
Should I defoliate the remaining primarily yellow-brown, water stress damaged leaves on the hulkberry, or are they functioning and contributing to the growth of the plant and not harming it?

Nutrient deficiency?
What type of deficiency is this? I think is from lack of nutrients in the soil. This auto been in the 3 gallon pot mixed with Gia green 4-4-4 for a month with just watered. I fed her ff tiger bloom 1 day ago to get her some food. What should I do?

What can be the cause of this? deficiency or toxicity?
Hello! I'm on week 8-9 on my auto from Atlas Seeds, I have a grow journal of her, a few days back some yellowish on the outer parts of the leaves started to appear, I got a picture today that may give some insight into it.
