Hi @Bimbadabang the discoloration between the veins of the leaves seems to me to be the beginning of a lack of calcium but it is also possible to be lack of magnesium. The burnt spot on the leaf seems to me to be slightly PH changes, it regulates the PH of all irrigation to PH 6. good luck mate 👍

Clones are degenerating, help!It started with yellowing between the veins and I thought it's Mag deficiency, already ordered Epsom Salt. Today many leaves started dying. Is it just Mag def. or something else? Shouldn't be over watering.

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.

Light spots on leaves I have some spotting starting on a few leaves. I had some slight tip burn last week I believe from letting the soil get too dry and getting a bit of nute burn. Two leaves showing these symptoms.

Blue Dream Autos with Downturned Leaf Tips 23 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?

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?

Strange discoloration The 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.

Upper leaves are yellow and not smooth I 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?

Is this an Iron deficiency? The tops and new growth look too yellow and the veins are yellowing with a darker green in between Haven'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?

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flower The 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.
