Possible light stress?
Mrgreengrinchstarted grow question 3 years ago
Any help would be much appreciated, so the leaves are looking with a yellow tinge , my thoughts were light stress as had lights on 24/7 on to high and to close I have since then back off on the power of the lights and move them further away from the plants and changed to 20/4.

Hi there, I think you have Magnesium lock out due to imbalance pH.You mention that your pH is 6.1 and you are using dripping system.What is your run off pH and ppm.Let the water to be run off about 10~15% and check.Happy growing... ✌️

I agree with your light stress guess, I had a similar issue when I switched to LEDs and kept underestimating their power. Are the leaves brittle / crispy / crunchy? Brittle leaves that break when bent is also a sign of light stress.

Your ph needs to be in the range of 5.5 to 6.0 max for veg. 6.0 to 6.5 max for flower. Cheers

Does that look like an early deficiency?Hi everyone, what ya thinkin'
What kind of deficiency could that be?
My bet - potassium.
last portion of water was ~6.2 pH
I wasn't feeding her nutes for ten days by now.
Because previous runoff was ~2000 ppm. I thought would be a good idea to do just water for a while.

Interveinal chlorosis and dead spots on leaves, deficiency?This started appearing about a week ago, after I watered until runoff with plain water. It's on a couple of leaves higher up both plants and seems to be progressing. I am feeding advanced nutrients Grow Micro and Bloom but have been using very low doses, like 1ml/L.

Blue Dream Autos with Downturned Leaf Tips23 days old. One started showing downturned leaf tips on new growth; others followed. Looks off-color, at least one is in early bloom. They’re in coco, 3-gal pots, 480W QB at 50cm, 2.2 EC daily, no pH check. Problems started after adjusting watering for larger plants. Any tips?

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Slight Leaf Discoloration. Early zinc deficiency?Girl showing slight discoloration on newer leaves. Mostly interveinal + little on the tips. Guessing it's an early zinc def. but would like another opinion. Watering sparingly at ph 6.3 - 6.5. No runoff yet, so ph may be higher in soil. Lower ph and watering til runoff next time?

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flowerThe odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.

Is this an Iron deficiency? The tops and new growth look too yellow and the veins are yellowing with a darker green in betweenHaven't fed much with nutes, when I did it's been low doses. I'm trying not to burn one for once. Not sure if its a deficiency or other problem or if I'm just worrying too much, looks off to me though. My problem with overwatering might be contributing.

Is it time to feed nutrients now or can I wait?I have not given any nutrients yet but I'm wondering if I should.
1. Are these really signs of nutrient deficiencies?
2. Which nutrients are missing?
2.1. My guess is P, N and/or Mag, Cal. Is that a good guess?
3. Is BioGrow a good choice to address these deficiencies now?

Upper leaves are yellow and not smoothI noticed leaves on top are closing and today are yellowish. Older plant aren’t stretching more, I thought it’s too much light or too hot but it’s kinda weird because light are at 40cm from longer plant and 50 from smaller, temperature are max 26C. So, it’s normal?
