Hello. I am a total newb in growing anything really. Setup: 2 14 gallon tubs, one a reservoir 2 small oscillating fans Advanced nutrients for veg state. oxygenated water with 10 air stones. 5 in flower bin, 5 in reservoir 1 rotating water head pump in flowering bin CO2 dosing via a filtered 3-way 3 gallon water system with yeast/sugar in first two, final filter stage through pure water. Doses a few big bubbles every 5 seconds 220 CFM 6" air outtake Air intake from outside filtered 2x125Watt CFL 1 500WATT LED Water heater set to 72 Constant tent temp 77 degrees Humidity around 33 pH at 6.0 water ppm 55 Bought the clones in rock wool? two weeks ago and have them in 6" net pots. water is just below the media. I reset the plants a few days ago and the roots were popping out everywhere! So that's good I guess. My question is why the odd coloring? They were green as green could be when I got them. Now they look a little sad, purple and yellowish and slightly wilting.
I think you have nutrient lockout. This happens your plant(s) can not access specific, or all nutrients in the growing medium, this is due to a chemical reaction within the medium/solution which prevents nutrients from being absorbed by the roots. Aged nutrients can precipitate in the bottle, causing some of the ingredients to become solids or even evaporate, the same problem may also occur in the growing medium. Lockout will display the same symptoms as nutrient deficiency; to help control this problem dispose of old liquid feed containers as you would old medicine and use fresh nutrients from a bottle that has been recently opened. The following points can also be responsible for nutrient lockout. PH is incorrect or fluctuates. Single pack hydroponic solutions. Salt build up. A chemical reaction between 2 or more nutrient solutions that are mixed together. For acute deficiency symptoms caused by toxicity and nutrient lockout a first Aid program should be immediately administered. Step 1) Leach the plants roots and growing medium using a professional leaching agent to thoroughly leach away metals, calcium, sodium, chlorides, sulphates and many other compounds, which can build up in the growing media. Step 2) Feed with 1/4 strength high quality complete plant food mix along with a high quality vitamin B-1 product such as Superthrive (1 drop per gallon). Step 3) Spray a professional stay green formula on the leaves. After 24hrs, spray the leaves with a quality vitamin B-1 product. Feed at 25% of recommended fertilizer dosage until first signs of growth. keylime
It seems I was deficient in mag-calc. I added the proper dose and even a couple hours later I can see the leaves beginning to firm up and fan out again. We'll see if the color comes back.
