Click here for more images: http://imgur.com/a/ruF0s#KDM8b Just wondering if any of you fellow growers can help me out with a quick diagnosis? She's at week 3 and was flushed through a week and a half ago (just to clear any salt buildup). Only had 1 feeding since flower at very low concentration with a pH of 6.4 - 6.7. It seems to affect the middle/top of the plant. It started going like this a few days after it was watered with just RO water. It began off as a whiteish colour making me think it was too close to the light - I had a 600 about 8-9 inches away, so I moved it higher. Temps & RH are good and stable. They were transplanted from coco into compost & perlite, and are in 17L pots/ 4.5 gallons Problems getting worse but im not sure whether its pH problem, deficiency or what! Any other information you need to help diagnose? Lemme know!
What type of medium; soil or hydro? Soil What brand and type of soil? Levington Multi-purpose Compost Indoors or outdoors? Indoor What strain? Reserva OG Kush How old are the plants? 17 Weeks, 3 weeks into flower What type of lights and how many watts? 600w HPS How far from the lights? 14-16 inches What is your watering frequency and source of water? every 4-5 days R.O Water What, how much and when was it fed? NPK? Last fed Dutch Pro Bloom A+B(A: 4-0-4 + B:2-2-4) & explode What is the medium/runoff pH and PPM if in hydro? What are the temps and humidity in the room? 70-80f 50-60% What size pots? 17L/4.5 Gallon Any bugs? Look real close. Bug-free (thank fuck) Any other pertinent info? Has been in the 17L pots for 2 months roughly, got much bigger plants in them too and theyre still super healthy, but theyre other strains. Was super healthy in veg, health has just declined since beginning of flower really.
I think it could be over feeding or needs to be fed what is your feeding schedule and what are you using
