Week 4 closet grow... WTF??? HELP PLEASE!!!

Tips, Tricks

1. if you rub the brown leaves and a rust comes off on your fingers it's fungus. if not it's ph causing lockout
2. your doing too much
3. That is a fungus problem your humitey is too high
4. Its rust fungus bro!
5. brown spots on leaves yeah bro ph let soil dry out bone dry then water with 6.2 water 
6. What are you Ph your water/nutrients at? It looks a little like Ph trouble, to high or to low! I Ph my mine at 6.2 to 6.3. Peace
7. How often are you watering? Looks like it could be an overwatering issue. Let em dry out. Also only do a complete flush as a last resort. flushing is not a good thing. Let her dry out then straight ph water and you will be fine.
8. you never fix a burn with more chemicals.. 
9. dude below said to use more K, NO! Do not try to fix a burn with more chemicals EVER. Clip off bad leaves and follow directions below.. good luck to ya and happy growing
10. Raise your light 4-6 inches, no direct fans.. Flush with distilled water (and Kleen Flush) let dry 3 days. Flush again with distilled water (No kleen this time) and wait 3 more days. Try to allow the plants to dry between watering. Then water/feeding with 1 drop super thrive per gallon. No more cal mag this grow. Wait 10 days to use the fox farms at 1/4 strength. Never use nutes over 50%, it's just a waste. 
11. Yo do u have an Xbox 360 account? But look like nutrients burn of some what to me. When plants are little use quarter strength mix ok and check out growweedeasy . Com and check your problem their but take sick plants away from good plantz cause u don't want them sick to bro
12. Use a tsp. per gal of water. Stop your fertilizer for about a week. Always let the top of soil show signs of drying between watering to avoid root rot..Sick leaves will not recover but new growth will look healthy again. PS avoid watering during dark period as a rule. It will recover :-)
13. You could even have a combo of nutrient issues.First of all Ruderalis strains are known to be easily burned by nutrients. I never use them the first couple of weeks to begin with ,then I start low dosage.And you dont need to use them in soil but every 2 or 3 waterings. I would use water or a flushing solution and put enough until water comes out bottom of pot. Also I agree with everyone that said it looks like Magnesium def. Go to any drug store and buy some Epsom salt.It is pure Mag.
14. could be
15. flush and feed ph'd water fo the next time you are suppose to feed, then just 1/4 nute ...use some soil bacteria to help with nute pick up by the roots you will see a cazy difference 
16. Nute burn: fix by usin ph'd water only. u dont have to gro weed with all these fancy nutes. just feed ph'd water with 1/4 strenth for your whole grow nd ur plant will grow. its weed! Nute def: fix by using ph water. most problems start bcuz your water is not ph'd. but remember dont flood ur plant. pour water in your pot till you c it leakin out the bottom then stop.you want the top 1inch of soil to be dry be4 u water again .just dont babysit the plants theyll gro.. chk for watering, def & bugs!
