what strength nutes should i used to foliar feed? using DM penetrator as well i tried it at 700 ppm (1lt from the nute tank premixed and 1lt plain water) with the recommended dose of DM penetrator (20ml per litre) did this and repeated 2 days after. a few days later i noticed discolouration around the top canopy (particular new growth) of a kind i have never seen before i have foliar fed at 700 ppm before withough DM penetrator with no problems like this should u use a lower dose nute mix with DM penetrator (or is the DM penetrator a shit product and should i just not use it!) thanks

Hi people, I was checking in on my clones for my next grow and noticed that they are getting less light now and has put them on the edge of flowering. . I started taking them into the flowering room with the 400w HPS. I then take them ouside for a feed and set them up to sun till the sunset then up to the room indoors under the light. . Nitrogen is the most mobile element. Plants suffering from this deficiency are distinct in their pattern of yellowing. Yellowing - it's purpleish colour. Or is it purple before yellowing ? Yellowing starts on the older leaves and progresses upward, leavin…

Problem solving time…. Two different plants not sure if it is the same problem or not; I am thinking iron deficiency (probably wrong). If not iron, my second guess is a mag deficiency. I am not sure how to fix either problem… The is no necrosis, no purpling, all lower leaves are dark green. Coco/perlite, hand watering using Advanced Nutrients Sensi grow 2part. PH is between 5.5 – 6.5 (usually closer to 6) TIA~

Hey guys. I have this one plant which is VERY yellow. and only on the canopy. Below the top leaves she is nice and green. I also have another 2 plants which are all identical (from the same mother) and they are fine and green, no problems at all. They are in soil So basically I have 3 plants, all the same, all being fed and watered the same, yet one is massively yellow on the canopy. She is also the closest to the light but I moved the light further away, temps are fine (23 degrees at the top leaves) and its been like 2 weeks and still no improvement.... Thats about a week ago, since then she has got a bit worse, when I get the digicam back i'll take some more pics…

Does anyone know what might be causing the leaves from one of my plant to look like this? At first i thought it could be over-nitrification, but now im thinking it could be a deficiency of some sort...possibly a magnesium deficiency? It's slowy working it's way up my plant, and affecting the older leaves first. I also thought it could just be from a lack of sunshine, but now its happening to leaves in direct sunlight. I know it's not from over watering because i've been letting them dry out in between watering. Can anyone think of what might be causing this? Any help will be much appreciated.
