30 days into flowering...Lots of problems [Pics]

here you go buddy... youre gonna send me a bud now right?

Yellowing - Lower/Middle Leaves - Yellowing of the lower leaves/older growth is a sign of a possible Nitrogen (N) deficiency. Nitrogen is a transferable element (this means the plant can move it around as needed). If a plant is not receiving enough Nitrogen from the roots then it will rob Nitrogen from the older growth. Plants that are Nitrogen deficient will exhibit a lack of vigor and grow slowly resulting in a weak and stunted plant that is significantly reduced in quality and yield. In a Hydroponic system, usually the pH is too high and has locked out the available Nitrogen. In soil a yellowing of the lower leaves could also be an indication of a root bound plant (see Root Bound below).
Solution - First, check the pH, and adjust if necessary. The correct pH for marijuana is 6.3 - 6.8 in soil and 5.5 - 6.1 in a hydroponic system. Second, make sure you are giving the correct amount/type of fertilizer/nutrients. For the vegetative stage of growth marijuana needs a fertilizer/nutrient with a high Nitrogen (N) content like 2-1-1 (or 20-10-10).



Leaf Curling Up - Leaf curling up can be a sign of a Magnesium (Mg) deficiency caused by too low of a pH level. Magnesium deficiency will show as a yellowing (which may turn brown and crispy) and interveinal (in between the veins) yellowing beginning in the older leaves. Interveinal chlorosis (yellowing) will start at the leaf tip and progressing inward between the veins. It could also be a sign of excess heat and humidity in the grow room.
Solution - Check and adjust the pH level as necessary. When the pH is not at the proper level marijuana will lose its ability to absorb some of the essential elements required for healthy growth. If you're growing in soil Magnesium will begin to be locked out at a pH of 6.5 and lower, in hydro it starts at 5.8 and below. If the pH is correct, then add 1 teaspoon of Epsom salts per each gallon to your water. Or, to foliar feed them, add a ½ teaspoon per quart to a spray bottle. **Note- If your tap water is over 200 ppm Magnesium will be locked out due to the calcium in the water. Magnesium can get locked out by too much Calcium (Ca), Chlorine (Cl) or Ammonium Nitrogen (NH4+). If this is your problem we suggest using bottled or RO (reverse osmosis) water.

 

Nice camera, sweet pics you got there. Everything is developing nicely looks like and in flowering, I have read that the plant uses lots o' Nitrogen and will eventually suck the life out of all the fan leaves (see link below figure 10).

What are you ferting with, how often, what is your tap water ph, do you adjsut it and what is your soil pH? lol Lots o' questions but it will help to know.

Too high or low soil/water pH can create nutrient lockup and keep the plant from absorbing nutrients (ferts). If you haven't used some sort of lime in your soil mix chances are pH will drop. It's good to flush them out with pH 7.0 (neutral) water. The ferts and schedule you have are fine, I would try and flush them before anything else, check your pH.

you should have flushed them first, them waited a few days, then transplanted............when flused the water that comes out the bottom will be yeallow, like urine...........i think you have a rootbound plant that has ph lockup, and that's why it's showing signs of N and MG deff............your adding the ferts but the plants refusing them, due to the roots being at a bad ph level...........you'll need to flush all the salts that have buit up...........even though it's in a new home, it will still need flushed............if you lose too many of those leaves, ie the plants solar panels, then the yield will be greatly effected..................sorry if i sound like i'm preaching, but you need to do it soon, as you've not got a lot of time for the plant to fully recover, if it's allready been flowering for 4 weeks...............as for HPS.....how far from the tops of the plants is it?.............Peace out..........Sid

ps..........the closet needs to be completely dark.........no light leaks at all..........sometimes they can take a small dull source, like the moon, but that's outside.......try for darkness.........
