I never heard of a semi-auto before.What brand is your nutrients and does it contain any micro nutes like sulfur,iron etc?

 

[strakey]

Promix and yes it has chelated properties....i think it is a semi autoflower or autoflower. Nit sure. 15 freebies came in a baggie with no label on it.

Here is the best description i could find.

Semi-Auto Plant:
This refers to a plant that has some autoflowering traits or tendencies but does not always flower at a certain chronological age. The major difference between a true autoflowering plant and a semi-auto plant is that a semi-auto plant will be able to revert to a vegetative growth pattern under a 24h light regimen and even be grown into a mother and cloned, while a fully auto plant will not be able to achieve or sustain a vegetative growth pattern for any significant length of time. A semi-auto plant will usually start flowering with a reduction in day length, or when the roots get bound or when the food is changed to a flowering formula.

Your plant looks pretty good except for a few yellowing leaves but being that old she could be just wearing out so I wouldn't worry to much and just leave her alone and hopefully she will be done before frost comes around.I would stick with full autos that get done much sooner like sixty to eighty days.

Well the problem was that when i made a purchase of dragons from rcmc years ago i got these 15 freebies from various breeders...still growing out those seeds..not sure if they are photos( not these 2), semi autos or autos, male or female....i got lucky...the ph was a little high so i made sure to lower it a bit on the next feed....thanks for the help namvet

Thanks!!

Strakey-- for a plant in bloom, that feed is all wrong, bad ratios of NPK,...waaay to much N (showing in the buds poor formation), and 10-18-18 is pretty heavy for PK,...Are you diluting? Feed frequency?... I think you have some K toxicity, and/or nute burn causing the margin yellowing,... in-pot pH will be critical info to have for next step of treatment! likely, it's too acidic in there with all the K+,...
... semi-auto, unknown strain, unknown F generation, but I'm betting it's F1,... theoretically they shouldn't auto, but are still needing light reductions to initiate bloom,.. often bloom speed is faster than parent photo',... between the N (fucks with flowering) and the 14 hours of light, she's caught confused in the middle here I think,... that food needs to change for sure, since there's nothing to be done for the light hours,....

Hey Waira, thanks for hopping in here. I was feeding once a week for all my soil plants with that feed. Its hard to find a bloom feed with lesser ratio of n to pk. The ph was over seven so i was using rainwater with the feed and it was coming down to 6. If thats a p or k lockout it looks like ph to me but im not the expert. The plant is heavy with bud but not the main cola.....what do you recommend??
