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.

My dear fellow growers, I've just started growing with no experience and am experiencing some leaf issues. I'd like to ask for your help and sugg
The plants in the photo were planted on August 15th, and they haven't bloomed yet. I have very little knowledge about fertilizing, so I applied fertilizer every time I watered for the first month. I'm growing 9 plants in a 120x120cm tent and using two 240W full-spectrum lights.

Roots getting brown
My Ph probe didn't work, PH was at least more than 0.30 (maybe 0.60) than displayed. As a result they had multiple chlorosis, now septoria leaf spots and possible Pythium since the roots are getting brown. What would you do to save the crop ? Adding mycorrhizae? Thx!

deficiency symptoms
I'm a beginner and some plants are getting fallen leaves. They are being watered with the amount of approximately 10% of the volume of the pot and an average pH of 6.5. Runtz has Mag deficiency symptoms after I fertilized, is she also lacking N deficiency?

What can I do? Leafs starting to turn yellow. First grower
Yesterday, I noticed some leafs starting to turn yellow and also the tips of the top leafs to be a bit brown. So I watered (nutrition in the desc) and calmag 2 ml, because I thought it might be either lack of PK or cal mg. What else can I do? What about my watering schedule?

Is this sight yellowing normal or cause for light concern? No nutrients
Does it look like the new leaves on my 7 day pictures are slightly yellow? Or is that relatively normal with new growth? 20% perlite, 30% coco, 50% organic potting mix. Been really light handed on the water. waiting until soil is completely dry before watering more (1-2 days)

Los nuevos brotes de mi planta salen con un tono verde lima. En la zona que más luz hay parece empeorar, será un exeso de nutrientes/bloqueo o quema de luz? La lámpara está a unos 40 cm

Yellow leaves working out towards tips
Yellowing of lower leaves, from the stem working towards the tips. It’s been hot and they’ve been home alone for 5 days with just one water on the 3rd day. They had a small amount of bloom just before I left! During veg they were on fish mix, but not very much (1/2 dose).

Yellow leaf tips and edges
Hi I've got a problem that I've seen from the start of my grow and it's getting worse on older leaves now - zoom in edges and tips are turning yellow. I thought it was magnesium so I've dosed with Calmag but it's not improved - I'm Ph6.5 - any ideas?

High TDS and low ph runoff - Lockout? deficiency?
Struggling with some bad soil (beginners mistake). I water with dechlorinated tap water at around ph 7.4 and 400ppm (not feeding yet). But runoff ph is 6 and around 1000 ppm. Am I dealing with a N-lockout? why such a ph difference and high TDS value?
