Worried she's not getting food/water because of the root bound, fungus gnat problem?, or a pH issue? Before and after -

Thanks for the response I posted some pics. Your incite is greatly appreciated =)

Looks like you are running out of gas. A little bit of P and amino acids might help.

I question your watering though. A lot of those older leaves are drooping.

How are you watering? How much and how often?

Watering a cup at a time at this point to make sure it's getting in there - top is very hydrophobic. Built a slow dripper today to make this easier. Was watering 2-3 times a week when hot and sunny, about a gallon per plant.. think that's not enough?

Depends on your evaporation rates.

Think of it as a glass of water. You want the glass to be more or less half full when you irrigate the second time after filling the glass, and then only small quantities over the whole surface of the pot.

You never want the cap to dry out. After you have irrigated two, three or even 4 time that way, heavy water again until the water comes out the bottom. You may or many not need to water again the next day....

Always water in the morning or mid day. DO NOT PUT your plants to bed sitting in freshly applied water nor water in the evening.....

You may be able to pick up a pot and check the weight to give you an idea. Bigger plants need more water. If you are under plastic, that augments temps, more water.

Quality of water is a whole other issue.

Thanks so much for the help! Built a slow drip system for them, upped there flower nutrients and added "mammoth" and guano to the mix as well. They seem to be happier today.

Hey guys, got some problems with my crop.

Strain: 24k Gold aka Kosher Tangie (DNA Genetics)
Soil: Bio Bizz All Mix
Pots: 6,4 L Teco
Nutrients: Bio Bizz Top Max, Bio Grow, Bio Bloom, Fish Mix, ActiVera
Light: 250W HPS Cooltube
Distance between Light and Plants: 8 cm
Temperature: 20-26 °C constant
Humidity: 40 %

I repotted the plants about 2 1/2 weeks ago from 4L in 6,4 L Pots so that they have more Soil to leech nutrients from it.

About 1 Week ago the plants startet to get yellow on top, but not all..only about a half of them. They also start to get some Nutrient Deficiency at the bottom, so i fertilized them after the Bio Bizz nutrient schedule the last 2 waterings in a row.

I really cannot believe that they got already to little nutrients because i repotted them earlier. I also don´t think of overfertilization because i have only fed them 4 times till now.

Here are some pictures:



As you can see they are yellow on top, getting a nutrient defiency on bottom but are nice feeded and dark green in the middle, one week ago they looked this dark green all over the plant.

They also stopped strechting after 10 days and really did not grow much since then.

Please help me guys, its my first time growing Bio.

looks like overfeeding...sounds like light might be too close. 8cm? that's like 1 inch or so right? i suggest you add like 4-6 more inches.

Thanks for your answer! Some guys told me that you barely cannot overfeed with organic fertilizers and i only feeded 3 times till now.
But i will give them only water the next few waterings and see what happens.

Do you really think 3.1 inches with 250W Cooltube are too close?
