Nutrient burn/flush

[turksteelman]

Plants in 3 gallon pots. I nutrient burned them pretty bad about a 12 days ago. When I water, I make sure water comes out the bottom of the pot. Would I have by now washed out the excess nutrients or should I flush? I also plan on repotting them into 5 gallon pails also.

Well how are they looking?

This is a great thread to check out.

Good luck.

If you're getting clear runoff at the bottom of the pot, I'd go ahead and transplant into the larger containers. Adding a dilute feeding of a complete fertilizer (with micro nutrients) isn't a bad idea after a long flush, just make sure to keep it a very low strength. Also, a drop of Superthrive per gallon of water probably wouldn't hurt when you move them into the larger pots.

Here are the pics from the nut burn. Some of the burn is from the side T5 lights that I had to try to increase the light. The 4' 8 bulb T5 just isn't cutting it alone. Any thoughts?

If this isn't a nutrient burn please let me know. Sometimes I find it hard to make the call.

Can anyone confirm that I have a nutrient problem by looking at the pics in the above post? I must have over fertilized them about 14 days ago. I have also decided to keep them in the 3 gal pots they are currently in due to HO-T5 light issues and the fact they wouldn't fit under the 4'x2' light fixture if they were in 5 gallons.

Can you help give me an experienced look. My plants seemed to have received too much nutrients about 14 days ago. I want to keep them in 3 gallon containers. Do you see any additional problems I need to be aware of.
Thanks,

Looks to me like the leaves tword the bottom were sprayed with strong nutes, or possibly got splashed on while watering, and got burned as a result.
Kinda looks like overwatering a bit, too. Have you been watering a bit extra to help remove the nute build-up? Constantly wet soil can cause root rot. Let 'em dry out a bit between waterings.
If it was too strong of a nute mix, every time you water the plant with plain water, it effectively cuts the ratio of the nutes you had added. By now, they are possibly starving for fresh (weak, at first) nutes and micro's. Any idea whaty your ph is?
As for the lighting, I had been using a 4' x 4 bulb fluorescent shop light for veg for years, but have only ever used HPS's for flower.

Its very dry here so I almost have to water every 2 days, especially due to the 3 gal container and the size of the plant. Perhaps I will try to push it to 3 days. I use a moisture meter and only water when the probe inserted into the soil about 3 inches reads dry. However, you may be right about the overwatering. I will check tomorrow and see what the soil measures about 10" down. I also most likely washed out the nutrients. I will start with a weak solution tomorrow. Thanks for the inputs.

Good luck, and keep us posted. :thumbsup:
