I would agree you are probley right with your narrowed down thoughts on what it could be. As you said you are a first time grower and you trans planted root bound plants and was it after you transplanted them they got worse? Also i try to only have to transplant each plant only once, yet i think your proble is a slight nutrient deficiency. I also skipped using a PH Tester for years until we had a devastated veg and i couldnt figure it out? With total organics i had unkowingly been using clorinated water! Big Oops! I would alos use epsom salt but would also recomend a ph tester as there are kits that are pretty good and cheap. As you are only using a 250 i would bet a sllight nute deficiency and a bit of stress for double trans and root bound second trans. I dont believe your problem will get worse make sure your water is pure h20 and if need be give a quick flush and then start the nutes back up i didnt see you used miracle grow potting soil and that leads me to believe as first time grower you probley take pretty good care and sometimes can over do it as it does seem they may have been over hit with nutes even though scaled back never grow with miracle grow and miracle grow is not organic so be careful and next time go with something easier for a beginer and use roots or foxfarm as a base for flowering and keep your nutriens simple. Although i will also say that your plants have a strong root system and will continue to grow and the fresh growth is your sign to tell if the problemss getting beter or worse. Pull the remaining and most infected fan leaves to give more direct light to the botom branches. Just a few ideas to help then wont stress plant anymore by it trying to rebuild the health of unneccessary leaves. None of my recomendations are a must and i agree you may wanna add cal/mag lighltly but dont over do it they seem like they will pull threw just perfectly! Well done for a beginer! If you have any questions PM me any time. Also as stated try to keep on a consistant feeding schedual and as said check soils moisture befor watering at any time. I think you will be fine its a nice coctail and i would go light on some and go with the cal/mag and pk asMiraclegrow takes along time to be nute deficient so over nuting can happen easily Keep an eye on things and just Keep it Simple. Peace, SENSI/ SORRY I CAN RAMBLE SOMETIMES!

Hi Sensi,

Thanks for dropin by, I only transplanted after they got lime and droopy/burnt tips. Thought it was from root bound, but now im just thinking they were hungry.

I think its a deficiency of several nutrients. I too am running into the same problems, however my symptoms range from lower leaves yellowing, leaf edges browning, leaf tips browning and curling upward. I run a hydro NFT system, so adjusting nutrients is quite easy for me. At first I thought it was nute burn (leaf tips burnt and leaf edges turning brown), but my PPM was topping out at 800. Cannabis can handle a PPM of up to 1600! So I ruled out nute burn. I have some fungus gnats living in my root zone. The pupa (larvae) live on the roots and chow down to their hearts content. This will certainly effect growth and cause a myriad of problems. But i ruled this one out too because not all of my plants are displaying the same symptoms. So...after much research I'm coming to the conclusion that's its a deficiency. My nutrients are full on bloom nutes, lacking much N (nitrogen). My plants, now in week 5 of flowering are still looking for N. It's sucking what they can from the lower fans leaves, in turn, yellowing them which eventually die and drop off. The burnt leaf tips are likely a K (potassium) deficiency. I always thought this was nute burn, but this symptom is very similar to K def. A key note is that the leaf edges we're curling upward. I don't believe this is a characteristic of a deficiency. So in conclusion, I recommend you do a healthy flush with PH'd water (6.3 - 6.8) is ideal. Then mix your nutrients (half veg, half bloom) and give the plants a healthy watering. I bet you'll see improvement in a couple of days. Then use half strength bloom nutes on the next watering, slowing increasing to full strength. You're well into flowering so, you should be backing off nutes anyhow. One last note, watch your Ph. This is likely the cause of your problems. The wrong Ph causes nutrient lock out. I've learned that cannabis does well between 6.5 - 6.8, and N uptake is ideal in that range. Good luck. Let me know how things go.

How is the superthrive working? I've read not to use it during flower as it promotes root growth and not and bud growth.

I've never used it personally but many people like Subcool "super soil" mix, there's a thread on here on how to make it (look through Sibcool's profile if you're interested.)

Stay here I'm on the same boat. 4th week light greenish. PH pen wasn't calibrated and nothing but rain so I can't feed her. What was the problem...? I'm pretty sure mine are hungry

Hi Exception, +Rep for the answer! they are 30 days in flowering and I am planing on another 30 unless my girls tell me other wise.

Yes I do know that, but this is my 1st grow and am still unsure if this is "The Perfect Burn" where the plant is drawing the reserves from the leaves OR if a problem is starting. That is why I am here asking your help.

I had pretty much narrowed it down to:
1. Nute Defeciancy or Excess
2. Root Bound from 1.5 gal pots (have since transplanted to 5 gals)
3. Hungar, from 1/2 strengh nutes
4. Everythings fine and the plants are just completing their life cycle.

Thanks for the response and confidance that my girls are fine. But is that what you really think? that they are doing fine and this is nothing serious?

Thanks for helping to calm a 1st time growers nerves.
